When setting up your network, the SFP transceivers you use have great effect on the performance of your system. These SFP transceivers are compatible with multiple devices, but the compatibility of them depends on various factors. Two main factors that should be considered when selecting SFP modules are DDM functionality requirements and checking the ID code and lock out third party components. Here are some details about the factors you should know about SFP transceivers.

Does SFP Require DDM Function?

An SFP does not necessarily require the DDM functionality, but your application should be compatible with digital diagnostic functionality if it is present. Most designers forget to verify the compatibility before design then face...

The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for telecommunication and data communications. The form factor and electrical interface are specified by a multi-source agreement (MSA). It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. SFP transceivers can support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. SFP transceivers are upgraded from the traditional version with more flexibility but a smaller size.


Sometimes you may encounter the affairs like installing or removing fiber-optic SFP modules with cables attached. In fact, this is wrong. Because that way may cause damage...

In order to cut down the costs on the expensive SFP transceiver modules, many users are seeking for a compatible SFP to use. For example, if your network contains HP routers, firewalls, and switches, you might think that only HP SFP branded transceivers will ensure your equipment functions optimally. However, that seemingly reasonable assumption could cost your company thousands of dollars. Compared to the compatible SFP transceiver produced by third-party companies, HP SFP transceiver comes with dramatically inflated price tags while a third-party compatible one is roughly 80 percent less expensive than HP branded SFP transceiver. Although price isn't everything, it's important to know that you're getting your money's worth. That calls...

In the 10 Gigabit Ethernet world, fiber optical transceiver modules have been developed to meet the increasing demand for higher-performance servers, storage and interconnects. XENPAK was the first MSA for 10GE and had the largest form factor. X2 became the later competing standard with smaller form factor, among which there are X2-10GB-SR, X2-10GB-LR, X2-10GB-ER and X2-10GB-ZR series. XFP came after X2. Then smaller SFP (small form-factor pluggable) enabling greater port density followed the XFP. The newest module standard is SFP+ transceiver (the enhanced small form-factor pluggable transceiver) which has become the most popular socket on 10GE systems.
