Guide to SFP+ Transceivers

Since March 1999, the Ethernet industry has been working on Providing Solutions to These problems by Increasing the speed of Ethernet from 1 to 10 gigabits per second. For enterprise LAN applications, 10 Gigabit Ethernet enables network managers to scale Their Ethernet networks from 10 Mbps to 10,000 Mbps, while leveraging Their Investments in Ethernet as They Increase Their network performance. Meanwhile, the newest module standards, namely the enhanced small form-factor pluggable (SFP +) transceiver has been developed to meet the Increasing usage and demand for higher-performance servers, storage and interconnects in the 10 Gigabit Ethernet world.

What is the SFP +

The small form-factor pluggable plus (SFP +) Can Be Referred to as an enhanced version of the SFP That supports data rates up to 16 Gbit / s. The SFP + specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009. The SFP + supports 8Gbit / s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry formats supported by many network component vendors. The SFP + product family includes cages, connectors, and copper cable assemblies. The SFP + transceiver modules are Specified for 8Gbps / 10Gbps / 16Gbps Fibre Channel and 10 Gigabit Ethernet applications.

Advantages of SFP + Transceivers

SFP + transceiver Comes With various outstanding advantages. SFP + covers various data rates for different communication standards like Ethernet, SONET (OC-192), SDH (STM-64) or 10G Fiber Channel and any other interfaces with a data rate up to 16 Gbps. It is with more compact size and measurement forms than X2, XENPAK and XFP, SFP + Which enables Suitable for installation with higher port density. In addition, SFP + takes the advantage of lower power consumption for less than 1W, like 455883-B21 compatible 10GBASE-SR SFP + transceiver shown in The Following picture. SFP + transceivers are managed with Digital Optical Monitoring and superior high temperature performance. The Therefore, it is a Cost Effective way to connect a single network device to a wide variety of fiber cable distances and types using a SFP + transceiver module.


Applications of SFP + Transceivers

SFP + transceivers are Designed to use together with small form factor connectors and sacrifice high speed and physical compactness, Providing instant fiber connectivity for your networking gear. They are available for copper and for all common modes of fiber, wavelengths and data rates and allow network operators to connect different interface types to the Same Network Equipment, via an SFP + port. To take advantage of this flexibility and to save money, more and more are being Network Equipment Designed with SFP / SFP + ports. Several industrialists acknowledged standards for SFP + havebeen made ​​for 10Gpbs networks, including 10GBASE-SR Which defines the SFP + transceiver working with OM3 10G multimode fiber at 30 to 300 meter range, 10GBASE-LR Which defines the SFP-10G-LR Transceiver Working with single mode fiber at 10km range, and so on.

To conclude, the 10 Gigabit Ethernet has Become the technology of choice for enterprise, metropolitan, and wide area networks. In terms of physical media, the 10G SFP + transceiver can support distances to 300 meters on multimode fiber and 40 km or more on single mode fiber. Fiber Store is a leading supplier of SFP + transceivers. We have a large selection of SFP + transceivers in stock, Such us SFP + MM 300m, SFP + 10km SFP + 40km SFP + 80km, CWDM SFP + DWDM SFP +, bidi SFP +, etc. All of our SFP + transceivers are tested in-house prior to shipping to ENSURE That They will arrive in perfect physical and working condition.

How to Choose the 10G Transceivers

From the origin of 10G Ethernet, 10G optical transceivers have been developed along the way to meet the increasing demand for higher-performance servers, storage and interconnects. However, selecting the best type of 10G optical transceivers is not always easy. There are a variety of factors that must be considered. To be able to select a matching transceiver for a given application and hardware, all below stated parameters must be considered.

10G optical transceivers

Transceiver “form-factor” / MSA Type

The transceiver has to mechanically and electrically fit into a given switch, router etc. Transceiver MSAs define mechanical form factors including electric interface as well as power consumption and cable connector types. XENPAK is the first MSA for 10 Gigabit Ethernet. The XENPAK MSA defines a fiber optic or wired transceiver module which conforms to the 10 Gigabit Ethernet standard of the IEEE 802.3 working group. Then X2 followed with smaller size. XFP specification was launched after X2 with more contact size. SFP and SFP+ are the newest and the most common form factors which enable 10G Ethernet.

Transport Media

Choose the right 10G optical transceivers according to the transport media, namely the fiber type. There are a number of 10 Gb/s media systems, with a few of the most widely used systems specified in the standard described here:

  • 10GBASE-CX4
    10 Gb/s Ethernet over short-range copper cable assemblies (15 m maximum).
  • 10GBASE-T
    10 Gb/s Ethernet over unshielded and shielded twisted-pair cables. Category 6A or better twisted-pair cables are required to reach the maximum distance specified.
  • 10GBASE-SR
    10 Gb/s Ethernet over short-range multimode fiber optic cables.
  • 10GBASE-LR
    10 Gb/s Ethernet over long-range single-mode fiber optic cables.
Connector Type

Choose the right transceivers which are compliant with the proper connectors. The connectors widely-used mainly have following types: Duplex LC connector, MPO connector, and MTP connector (a high performance MPO connector). For instance, HP 455883-B21 10GBASE-SR SFP+ transceiver module provided by Fiberstore is compliant with the Duplex LC connector.

Transmission Distance

When we choose the ideal 10G optical transceivers, we must consider the transmission distance and the reach requirements we need in reality. The most common types of transceivers divided by its transmission distance can reach up to 100m, 150m, 300m, 400m, 1km, 2km, 10km, 40km, etc. For example, Cisco SFP-10G-SR compatible 10GBASE-SR SFP+ transceiver supports link lengths of 300m over multimode fiber cables. And Juniper XFP-10G-L-OC192-SR1 compatible 10GBASE-LR transceiver provides superior performance for SONET /SDH and Ethernet applications at up to 10km links.


The wavelength the transceivers operate with is an important factor in choosing the proper 10G optical transceivers. For instance, Fiberstore's 10G CWDM XFP is designed for single mode fiber and operates at a nominal wavelength of CWDM wavelength. There are fourteen center wavelengths available from 1350nm to 1610nm, with each step 20nm.

Fiberstore provides various types of 10G optical transceivers including single-mode and multi-mode with different channels and wavelengths. In order to achieve a fast and successful selection of the 10G optical transceivers, we should consider all the above-mentioned factors comprehensively.
