10GBASE-T Copper Switch Recommendation

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). And the 10GBASE-T copper ports are connect to servers and routers. Read more about Building Spine-Leaf Network with 10GBASE-T Switch

Conclusion

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.

Basics of Optic Switching

With improved efficiency and lower costs, optical swiching provides the key for carries to both manage the new capacity that dense wavelength division multiplexing (DWDM) provides and gain a competitive advantage in the recruitment and retention of new customers. However, with two types of optical swiches being offered, there is a dabate over which type of switch to deploy-intelligent, optical-electrical-optical (OEO) switches, or all-optical, optical-optical-optical (OOO) swiches. The real answer is that both switches offer distinct advantages and, by understanding where and when deployment makes sense, carriers can optimize their network and service offerings.

Carries have embraced DWDM as a mechanism to quickly respond to an increasing need for bandwidth, particularly in the long-haul core network. Many of these carries have also recognized that this wavelength-based infrastructure creates the foundation for the new-generation optic network. However, as DWDM delivers only raw capacity, carries now need to implement a solution to manage the bandwidth that DWDM provides. Optical switches advantage in the recruitment and retention of new customers. To secure improved efficiency, lower cost, and new revenue-generating services, carries have at least two choices of optical swiches to control their bandwidth and rising capital expenses (CAPEX), the OEO switch and the all-optical, photonic-based OOO switch, which will be discussed in complete detail in Section 10.1.3. A logical evolution path to the next-generation network must include the deployment of intelligent OEO switches to ensure that current needs are met and all-optical OOO swiches are added where and when they make sense. Therefore, there is no debate on whether carries need to deploy either OEO or OOO, but there is debate on how to optimize network and service offerings through the implementation of both switch types.

In addition, recent economic challenges have highlighted the fact that the network evolution must increase the efficiency and manageability of a network, resulting in lower equimpment and operation costs. A growing number of carriers have accepted the evoloutionary benefits of the optical switch. Carries must decide how best to implement the optical swich to gain a competitive advantage in the recruitment and retention of new customers. Promises of improved efficency, lower cost, and new revenue-generating services are being made by manufactures of two types of optical switches-the OEO switch and the all-optical, photonic-based OOO switch.

Now the following we recommend you two optical swiches from Fiberstore, they are Optical Bypass Switch, 1×2 fiber optic switch.
