FacebookTwitterGoogle+LinkedInRedditTumblrShare

In the past few years, network speeds have increased dramatically as applications like video and technologies like virtualization need higher speed and performance. Therefore, 10 Gigabit Ethernet (10GbE) is widely deployed for inter-switch and server-to-switch links. Generally, there are two 10G switch solutions for the aforesaid 10GbE link: 10GBASE-T copper switch and 10G SFP+ switch. And since the 10GBASE-T copper switch is more favored by the market, this post will focus on 10GBASE-T copper switch recommendation.

10GBASE-T vs SFP+: Why Choose 10GBASE-T Copper Link?

Many people may wonder why 10GBASE-T copper link is more favored by the market. This part will discuss this topic in a brief way.

As we all know, 10GBASE-T copper switch uses copper cables to transmit 10Gbps data. This may help to save much money because copper cable infrastructure is far less expensive than the fiber optics of 10 SFP+ switch. In addition, 10GBASE-T network is easier to be employed and allows users to make the best of their existing Cat6a UTP structured cabling ecosystem. Despite all this, 10G SFP+ link also has such advantages as lower latency and lower power budget.

10GBASE-T Copper Switch Recommendation

Since 10GBASE-T network is favored by many IT managers, lots of RJ45 10GBASE-T copper switches has been supplied in the market. These switches are either 2/4/8/16 port copper switch for home networks or 20+ port 10GBASE-T switch for enterprise and data center networks. This part will introduce a high performance 48 port 10GBASE-T copper switch with 40Gbe QSFP+ UpLink – S5850-48T4Q – for your reference.
10GBASE-T Copper Switch

S5850-48T4Q is a 1U managed L2/L3 Ethernet switch. It is designed to meet next generation Metro, Data Center and Enterprise network requirements. Featuring 48 10GBASE-T RJ-45 ports and 4 40G QSFP+ ports, it can provide 1.28Tbps switching capacity. And it has a forwarding rate of 952.32Mpps. The following table compares the key parameters and prices of S5850-48T4Q and other similar switches:

48 port 10GBASE-T Copper Switches

Seen from the above table, you may find that the ports and performance of the three 10GBASE-T copper switches are nearly the same, but Cisco Nexus 3064-T and Brocade VDX 6740T switches are much more expensive than the S5850-48T4Q. This is because their prices include both the actual value of the switch and their specific brands which are always costly. And their after-sale services may be better than most small companies. However, this FS S5850-48T4Q switch is also guaranteed with free tech support and back up support.

S5850-48T4Q 10GBASE-T Copper Switch for Spine-Leaf Application

Unlike most 10GBASE-T copper switches, S5850-48T4Q can be used for Spine-Leaf network which is a popular architecture design for data center. To be specific, S5850-48T4Q is often used as the leaf switch in a 40G Spine-Leaf design. As shown below, the 4OG QSFP+ ports of S5850-48T4Q often used to connect to the spine switch (S8050-20Q4C).

For lower cost and ease of use, 10GBASE-T copper switch is popular among 10G network switches. If you plan to migrate to 10GbE network, 10GBASE-T copper network is a good choice. It will help to reduce the cost complexity and cabling issues around the migration to 10GbE in the data center.

10G Twinax vs Fiber: SFP+ Copper Cable or SFP+ SR Module?

Over the years, 10GbE has successfully stretch its reach from enterprise data centers to midmarket networks due to the increased bandwidth requirements and the growth of enterprise applications.   As the deployment of 10GbE is going boarder, it is important to understand how to effectively leverage the technology to better satisfy your network demand. Thus, all elements should be carefully reviewed to choose the appropriate cabling solution for your workloads. Many customers facing the problem to choose from 10G twinax vs fiber (SFP+ copper cable vs SFP+ SR) as both are viable options for short range. This is what we are about to figure out in this article.

10G Twinax vs Fiber: SFP+ DAC Cables Is Simple and Cost-Effective

10G twinax vs fiber for short reach connection? Before we go any further, it’s better to take a glimpse of what  SFP+ direct attach cable (DAC)are and what role they play. A SFP+ DAC cable, also known as SFP+ twinax copper cable, is effectively viewed as a transparent cable to the switch. It is a cable invented with each end physically resembling an 10g SFP+ transceiver, but with none of the expensive electronic components. Although being even more pricy than fiber optic cables, SFP+ Copper Cables effectively eliminate the expensive optical transceiver required in the equipment they connected.

10g twinax vs fiber - 10g dac

SFP+ Copper Cables comes to two different flavors: passive and active. Passive SFP+ Copper Cables requires little to no direct power to operate, and are extremely affordable with the length ranging from 0.5m all the way up to 7m. Active SFP+ Copper Cables integrates signal processing circuitry into its built-in connectors and actively powering those circuits with DC power provided by the switch. The circuitry in active sfp+ cable thus brings up the overall cost. This partly explains why active sfp+ cable is usually more expensive than its passive counterparts.

10G Twinax vs Fiber: SFP+ SR Is Flexible and Future-Proofing

For 10G twinax vs fiber, we cannot make our decisions until we clear knows each function. SFP+ SR are similarly used for short runs, and that is exactly “SR” stands for – short reach. SR transceivers are almost always multimode, and optimized for high speeds over relatively short distances. It operates at 850 nm, and can reach up to 300 m with laser-optimized OM3 and 400 m with OM4. The 10G SFP+ SR transceiver module offer a flexible connectivity option for data centers, enterprise wiring closets, and service provider transport applications. The price is the major issue that some customers turn to SFP+ Copper twinax cable instead of SFP+ SR transceivers for short runs, especially for those who are under tight budget. Fortunately, third-party optics has narrowed down the price gap by providing decent performance transceiver modules with only a fraction of the cost at the original ones.

10G Twinax vs Fiber: Application Considerations

When choosing between 10G twinaxs vs fiber, the following factors have to be well considered.

10g twinax vs fiber - 10g direct attach cable dac vs 10g sfp+ sr module

Distance: Advocators of SFP+ twinax copper cable  insist that, if distance is not a problem, they tend to choose SFP+ cable  because of the lower power needs and lower latency it provides, and the power saving alone is significant. Not to mention that the cable itself is less fragile and more durable. As SFP+ twinax cable  only reach up to 10m, when distance happens to be a factor, SFP+ SR transceiver can get much longer reach and more compatibility anyway. Or if the switches are connected via patch panel, then your hand is forced to 10G SFP+ SR transceiver and fiber. To sum it up, SFP+ cables are used within the rack to connect servers and storage to ToR switches, it is an “intra-rack” thing, whereas SFP+ SR in for connection between racks – known as “inter-rack” cabling.

Cable management: in terms of managing cables, fibers are believed easier to work with – it has no limit of cable length as with SFP+ cables. As for bulky and thick SFP+ cables it is fine for same rack FEX extension or one or two servers, but load half a rack with a top of rack FEX/switch with twinax, you will have mass of inflexible copper at the back of the rack. And that can be a nightmare.

Cost: 10G optical transceivers are much expensive than 10G SFP+ copper cable – these might be the driven course for people using twinax over SR optics. However, the booming of third party optics well addressed the issue by providing full compatible and trustworthy transceiver modules, which on the other hand, significantly reduces the cost of optics. Since the price gap between SFP+ cables and SR SFP+ optics is reduced, it bestowed customers more chances to weight other affecting factors.

Uniformity: users prefer to use SFP+ SR indicates when working with different vendors, it’s less likely to run into issues if you use optical transceivers. Truly, SFP+ SR indeed makes multi-vendor environment cabling much easier: imagine that you have to connect two switches from different vendor, simply use two SR transceivers that compatible with each brand switch can well solve the problem. However, if cost really matters, you can equally choose this special made SFP+ twinax cable from FS – different brands can be made at each ends, which are compatible with the major vendor on the market.

Conclusion

10G twinax vs fiber, from a network perspective, the SFP+ twinax cable is fine and a lot cheaper for very limited short runs – typically intra rack cabling, while for mass adoption, they become absolutely thick and unmanageable. So it’s worth the savings if your switch is in the same rack as the equipment you are connecting, and if it goes to another rack, SFP+ SR with fiber and a patch panel can be a sound option. With SR optics, you have much more flexibility in the placement of servers and how you lay out your racks. It is the obvious choice once the demand for bandwidth and length becomes more acute and cable management and future growth becomes critical.

One LC Switchable Uniboot Cable Removes All Your Problem

Suppose that you need some LC fiber patch cords to build a data center and now there are common LC patch cable and LC switchable unibboot cable. What kind of cable will you choose? Considering the cost, you may select common LC patch cords. But think about that for a while, you may make the different choice. Let’s see why you need LC switchable uniboot cable.

How to Switch Polarity Easily and Quickly?

Have you ever changed polarity when running fiber patch cords? How long did you spend on finishing that? Did you make any mistake? Polarity is quite a complicated thing. Engineers must be very careful to ensure that the transmit signal (Tx) at one side should match the corresponding receiver (Rx) at the other side. If polarities don’t match, signal transmission may get impacted. Then how to do polarity conversion in an easy and quick way?

LC Switchable Uniboot Cable Help You Do Easy Polarity Conversion

We all know that polarity conversion of traditional LC cables would require to re-terminate connector. It takes much time and leads mistakes. What’s more, you need special tool to finish that process. Unlike common LC patch cords, this switchable uniboot cable supports the polarity to be switched without connector re-termination. Polarity changes can be made in the field quickly, without the use of tools, to the correct fiber mapping polarity. No damage to fiber.

How to Reverse the Polarity of LC Switchable Uniboot Cable?

To reverse polarity, you just need three steps. First, open the connector top. Second, switch the polarity you need. At last, close the connector top. No tools are needed during the whole process. Isn’t the LC switchable uniboot cable a good choice?

lc-switchable-uniboot-polarity

LC Switchable Uniboot Cable Is Good for Saving Space and Cooling

Except the polarity issue, engineers may come across the problem of limited space and airflow when building infrastructure in high density data center. How to deal with that? Switchable uniboot cable is absolutely a good choice. The cable is designed as round style of 2mm jacked cables instead of zipcord duplex cables, reducing cable size and increasing 60% density. So switchable uniboot cable is beneficial for saving space and cooling.

lc-uniboot-vs-standard

What Should Notice When Buying LC Switchable Uniboot Cable?

LC switchable unibboot cable is helpful to simplify switching polarity, save space, which is an ideal solution for high density data center. In case that you need, here are some suggestions for you When buying LC switchable unibboot cable.

  • 1. Connector is an essential factor. If the connector has a poor quality, it can cause optical loss. You are suggested to choose Senko connector which is famous for its high quality.
  • 2. For patch cords, the other important factor is fiber. As we know bending sometimes inevitable. Corning fiber is outstanding for its bending insensitivity. For single mode fiber, the minimum bend radius is 10mm. For multimode fiber, the minimum bend radius is 7.5mm.
  • 3. Pay attention to insertion loss (IL) and return loss (RL) for single mode and multimode cable.
  • 4. Find if the cable meets various standards, for instance, CE, IEC, ROSH, EIA/TIA, Telecocordia GR-326-CORE standards.
  • 5. Price is of course another point you care much. So find several vendors to compare the price and choose the one you accept.

Cisco ACI: Software-Defined & Hardware-Enabled Solution

Cisco ACI (Application Centric Infrastructure) has already gained much early support from the its data center partners. By creating a new way to link networks and applications in a highly virtualized data center, Cisco ACI is considered as “a revolutionary re-thinking of how to provision and manage data center networks”. Which has the potential to completely shift the way that large, highly virtualized data center networks are configured and built. So what is Cisco ACI all about? How can ACI benefit our network? This article may explain it to you.

Cisco ACI: An Optimized Solution for Data Center

Cisco ACI mainly consists of two components. The first is the Application Policy Infrastructure Controller (APIC), which can be seen as a virtual machine. The APIC holds a database of application configuration information, and works to turn this information into network configurations and push those configurations into devices. The second is a set of real and virtual network devices that are optimized for ACI. For example, devices like Cisco’s Nexus 9300 switches when run in Cisco ACI mode and with ACI-supported line cards.

Cisco ACI deployment

Generally speaking, Cisco ACI is Cisco’s attempt to solve the prominent and significant problem of integration between applications and networks. With ACI, there’s no “closedness” in how you access the system. Servers and top-of-rack switches can be changed without requiring associated re-definition of those models. The benefit is that organizations can rapidly provision and migrate resources based on application policy, reduce the cost of operations, shorten application deployment time and make “on the fly” changes. In a sense, Cisco ACI brings “just in time” provisioning of IT resources to the world of applications.

Cisco ACI for Data Center: More Than a Configuration Tool

Cisco ACI captures the “intent” of an application directly from the application owner, which allows for the application owner to control their network provisioning, creating a consistent and documented configuration in network elements. The data center network is thus presented as abstractions that make sense to the application owner. This simplifies scalability issues that tie up network managers, such as subnets, VLANs, virtual routers (VRF), and access control lists (ACL). Therefore, much less time will be spent on configuring, troubleshooting, and debugging data center configurations – which can be a pretty good thing for network managers. The advantages of Cisco ACI is listed as following.

Cisco ACI advantages

Cisco ACI builds the data center fabric on top of VXLAN, which allows any-to-any layer 2 connectivity – seems not a big deal in traditional server environments where each server stays connected to the same set of Ethernet ports all the time. But when data center moves to virtualization, a single physical server may have dozens of virtual servers, each with their own MAC address and their own layer 2 connectivity requirements. More importantly, as those virtual servers migrate between physical servers, there’s a requirement for the network to keep everything straight so that each virtual server is properly connected to its VLAN and subnet. In this case, the ACI-aware VXLAN fabric in Nexus 9300 makes a critical and valuable part of the system. The following picture shows Cisco ACI fabric topology with Nexus 9300 switches.

Cisco ACI fabric

Cisco ACI Moves Data Centers to the Cloud

Since the early goal of Cisco ACI is to offer customers alternative on how and where they run applications, it now supports multiple hypervisors, bare metal servers, and Linux containers on premise and has become the most open, flexible and widely deployed SDN in the industry. ACI presents an ideal choice to enhance operational efficiencies, deliver network automation, and improve security for their on-premises data centers and private clouds. And it has stretch the reach to public cloud domain. Consequently, ACI enables users more flexibility to run applications across their private clouds and public clouds, with the ability to maintain consistent network policies across their entire multimode domain.

Conclusion

Cisco ACI combines traditional switching technologies with advanced management and automation capabilities, allowing the customers to shorten application deployment time, streamline operations and reduce operating expenses. As a member of Cisco’s popular Nexus 9300 switch family, Nexus 9372PX is a ACI-supported switch using as a leaf nodes in Cisco ACI fabric. FS N5850-48S6Q switch has the same port configuration as ACI-enabled Nexus 9372PX: 48 fixed 10G SFP+ ports and 6 fixed 40G QSFP+ ports that delivers 1.44 Tbps of bandwidth, but with only a fraction of the cost. FS offers a wide range of solutions to help deploy N5850-48S6Q in your data center, visit www.fs.com for more tech support.

Can I Connect Optical Transceivers of Different Brand?

Data centers generally accommodates hundreds or even thousands of network switches, it happens when you have to connect switches from different vendors (i.e. switch X from Cisco and switch Y from HP). As the switches only fit their own brand-based optical transceivers, the main issues thus falls into this: is it possible to contact two different vendor’s optical transceivers and form a viable link? The answer is yes – but you still have to take some critical aspects into account.

connect optical transceivers from different brand

A Basic Case Study: Standard of Optical Transceivers is the Key

Sometimes people have to mix switches and optical transceivers, mainly because the following reasons:

  • They already have brand X and they need more switches and they shop on price. Hence different brands
  • They need to replace switches but do not have money for all and they buy brand X and plan on going to brand X completely but it takes time to get there.

There exist quite a lot standards and protocols concerning optical transceivers. Although many installers are very familiar with linking different vendor’s switch, the others are still worried that the incompatibilities of two transceivers may impede the link performance. They may come across the questions like “Can I order a 1000BASE-LX transceiver from any source and it will be compatible with all others 1000BASE-LX?” or “Would a link with a Juniper 1000Base-LX and a Cisco 1000BASE-LX transceiver work?”

1000base-lx optical transceivers

Ideally it should work. 1000BASE-LX is a standard the same way 1000BASE-T is, except that it uses fiber as the transmission medium. You’ve already known that any copper interfaces with 1000BASE-T is interoperable since they are defined by the same 1000BASE-T standards. So you can expect the same with fiber 1000BASE-LX interfaces –  which are all defined by 1000BASE-LX. While this is true on the fiber side of the system, and should be true on the thing with the transceiver socket. In fact, you can rest assure as SFP is multi-vendor standard that specified by a multi-source agreement (MSA). And it is a popular industry format jointly developed by many network component vendors.

Further Consideration of Optical Transceivers: Protocol, Transmission Wavelength and Cable Type

Connecting SFP optical transceivers from two different vendors still have some other restriction, since SFP transceivers differs from one another in protocol, interface type and transmission distance.

Ethernet Protocol: You have to pay attention that you use optical transceivers of the same protocol at each end, for example: both sides with SX, LX or whatever is currently in use. Otherwise, you have to undertake the risk of link failure.

Cable Type: The optical transceivers on each end must use the same fiber type. An SFP made for multimode fiber isn’t going to work well, if it does at all, with single-mode fiber. Same applies with other multimode fiber types: although mixing various 50 um fibers (OM2 and OM4) may work OK depending on data rate and distance. As long as each end is the same fiber type, you can mix vendors and even connector types, such as SC on one end and LC on the other end.

Wavelength: It is vital the wavelength of the optical transceivers (850nm, 1310nm) matches on each end, as a 1310nm transceiver will NOT talk to a 850 nm transceiver. MMF has a lot of loss, and the wrong wavelength may cause loss and degradation on the longer runs. As for SMF, you need to be even more careful about wavelengths though, especially for long distance. So, if you are on the working range, all the transceiver will work normally.

wavelength for optical transceiver

Conclusion

It is hence safe to say that when connecting two optical transceivers from different vendors, you can expect you fiber patch cable to lead a consistent link as long as you use modules of the same Ethernet protocol, cable type and working wavelength. FS provides fully compatible optical transceivers with affordable price and decent performance. For more information, please visit www.fs.com.

What About 10G Cabling – 10GBASE-T, DAC or SFP+?

Upgrading the existing 1G network to 10G can be simple. As 10G switches also support 10GBASE-T, you can use the same RJ45 network cable to connect the 10G switch with your servers, storage and some other switches. The only difference is to use Cat6a network cable instead of Cat5e and Cat6 cable, or choose SFP+ 10GBASE-T modules with 2.5W power consumption and a maximum distance of 30 m.

10g-copper-fiber

For 10G switches that support 10G SFP+, you should use these ports if you have devices that come with 10G SFP+ port, or you need a 10G connection to other switches over 100m away. SFP+ ports look just the same as SFP ports on your Gigabit switches, but they’re now running at 10 Gigabit. For servers or storage devices with 10G SFP+ port, the most cost efficient way to connect is to use 10G DAC (direct attach twinax cable). These are basically copper cables with SFP+ connector on both sides, and they come in various lengths.

10g-dac-cable

To connect switches over 100 m apart, a pair of SFP+ modules and the matching fiber cable are needed between them. Depending on the length required in home network, you can use 10G optics such as 10GBASE SR SFP module and multimode fiber to reach 300 meters. FS offers a wide range of 10G SFP+ modules and fiber patch cables for short and long distance transmission.
