10G SFP+ and 40G QSFP+ Transceivers Cabling Solutions

FacebookTwitterGoogle+LinkedInRedditTumblrShare

This article will discuss different connection methods between parallel Quad Small Form-factor Pluggable (QFSP+) transceivers and Small Form-factor Pluggable (SFP+) transceivers. As we know, a QFSP+ transceiver can be either an 8-fiber parallel link or a 2-fiber duplex link. In this document when QFSP is used we will be discussing an 8-fiber parallel link. A SFP+ transceiver is usually an 2-fiber duplex link. According to standard, since QSFP+ is 40G interface, SFP+ is 10G interface, therefore four SFP+ transceiver must be needed to connect to one QSFP+ transceivers to achieve 40G transmission.

Direct Connectivity Solutions
When directly connecting a QSFP port to the four corresponding SFP ports, an eight fiber MTP-LC harness cable is required. The harness will have four LC Duplex connectors and the fibers will be paired in a specific way, assuring the proper polarity is maintained. This type of direct connectivity is only suggested for short distances within a given row or in the same rack/cabinet.

Interconnect Solutions
The interconnect solution shown in figure below shows one link with a breakout of the QSFP with the use of an MTP-LC module to four SFP links. A Type-B non-pinned MTP to non-pinned MTP cable is used between MTP-LC modulethe MTP-LC module and QSFP transceiver. The connection to the SFP transceivers is accomplished with Uniboot LC duplexed jumpers. This is a solution that is only recommended for short distances, where the patching takes place within a given row of racks/cabinets. This solution does present some disadvantages which are that ports 5 & 6 of the module are not being used thus reducing the patch panel density. It may also create some confusion when patching occurs since these two ports are dark.

Unlike the patching approach in figure above, the solution shown in figure below has no dark fibers oLC-LC adapter panelr ports. The Type-B jumper is replaced with an eight-fiber harness. The modules are replaced with the LC-LC adapter panel. Using this approach allows full patch panel density that was lost in the previous example. Only two LC-LC adapter panels will be required for every three 8-fiber harnesses. All ports on the LC-LC adapter panels will be used and the connections to the 10GbE ports will be completed with an Uniboot LC duplexed jumper. This solution should also be deployed when there is a short distance between active components (within the same row). Note the LC panel does not support the LC Uniboot connector, only LC Duplex connectors with the triggers removed to avoid clearance issues with the panel cover.

Three Ways Fiber Optic Transceivers Promote Data Center

The data center is one of the most critical and dynamic operations in any business. As companies produce, collect, analyze and store more data, IT infrastructures need to grow as well to keep up with the demand. With all the data processing and transmission, it is only critical that every design aspect and component of your data center is properly optimized, including its fiber optic transceiver technology. The transceiver and other optical components need to meet the bandwidth requirement for storage, switch, and server applications. Now let’s see how will the optical transceivers promote data centers in the future.Fiber Optic TransceiversSmall Package Makes Sense
Optical transceivers are becoming smaller, but more powerful, which makes them an important piece in server technology. In fact, even though a transceiver is physically small, it can handle a network expansion or an entire install. This shrinking of transceivers allows for the improvement of servers. This reduces the overall footprint of servers and networks, which makes data centers smaller and streamlined. Optical transceivers also require lower power consumption, which means you get lower costs both in terms of design and electricity expenses.

Data Center Makes up Big Transceiver Market
Optical components are always being improved, which can only mean good things for data center managers. According to recent numbers, 2016 and beyond will be huge for the data center market and optical components as more companies require efficiency in their networks. Data centers make up 65% of the overall 10G/40G/100G optical transceiver market. Shipment of 10G transceivers continue to grow, but still has plenty of room to grow, especially as industry experts expect the Datacom optical transceiver market to reach $optical transceivers2.1bn by 2019.

40G and 100G Transceivers Pave the Way
Consumers and technology experts can expect optical transceivers to improve as data centers grow and the cloud industry expands. Manufacturers have introduced transceivers that can transmit data at 40Gbps and 100Gbps, while some startups are investing millions in developing technology that can achieve higher speeds. These and other improvements can only mean good things for businesses and consumers.

Significantly improving your company’s IT infrastructure is becoming an essential task, especially in this data-driven world. Optical transceivers and components are some of the little things that definitely can make a big difference in this effort. Fiberstore provide a variety of fiber optic transceivers with high quality and low price, from 1000Base SFP to 10G SFP+, 40G QSFP+ and 100G CFP. For more information, please visit www.fs.com.

Great Compatible Cisco SFP+ Transceiver Modules

transceiver moduleThe enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 16 Gbit/s. Since SFP+ is mostly used for 10G, we usually call it 10G SFP. It is a popular industry format supported by many network component vendors. In terms of the SFP+ transceivers, there are various major brands, such as Cisco, HP, Juniper etc. In the current market, the Cisco SFP+ transceivers are very popular with the customers, especially the Cisco SFP-10G-SR and SFP-10G-LR. However, these original transceiver modules are really expensive. To save cost, we usually use 3rd-party transceiver modules instead of the original brand. In this text, two kinds of compatible SFP+ modules that can severally replace the Cisco SFP-10G-SR and SFP-10G-LR will be introduced. These two kinds of compatible modules are all from the Fiberstore, the leading manufacturer and supplier of optical transceiver modules in China.

SFP+ is the Most Popular 10G Transceiver Module

Since there are many different 10GbE physical layer standards, many interfaces consist of a standard socket into which different PHY modules may be plugged. On the market, the common 10G transceiver modules are XENPAK, XPAK, X2, XFP and SFP+. XENPAK was the first MSA for 10GbE and had the largest form factor. X2 and XPAK were later competing standards with smaller form factors. XFP came after X2 and XPAK and it is also smaller. The newest module standard is SFP+. In comparison to earlier XENPAK or XFP modules, SFP+ modules leave more circuitry to be implemented on the host board instead of inside the module. Now SFP+ has become the most popular socket on 10GbE systems.

Common 10GbE Standards for SFP+

10 Gigabit Ethernet is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Some common 10GbE standards for SFP+ are shown in the table below:

CWDM SFP+ and DWDM SFP+ are all operate on 10 Gigabit Ethernet
Wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths of laser light. WDM is divided into different wavelength patterns, conventional/coarse wavelength-division multiplexing (CWDM) and dense wavelength-division multiplexing (DWDM). CWDM and DWDM SFP+ are transceiver modules which are combined the CWDM or DWDM technology. This kind of SFP+ can allow you to expand your networks capacity without the need for physical fibre optic cabling.
