General information about Optical Transceivers

Picture of optical transceivers Optical transceivers or 'modular optics' are used in networks to transmit large amounts of data over glass fiber. They hold significant advantages over copper, such as low latency, longer distances and higher speeds. Modular optics are plugged into routers and switches, and offer a flexible and interchangeable solution.

To reduce costs of Research and Development, manufacturers like Cisco, HP, Finisar, and Juniper agreed to standard dimensions and specifications for these modules: 'form-factors'. The first form-factor for 1GE was the GBIC, (Gigabit Interface) the first form-factors for 10G were XENPAK. Both evolved to the same form-factor: SFP, (Small Form-factor Pluggable) which resulted in the same form-factor for the speeds 100Mbit, 1000Mbit and 10Gigabit. Although the dimensions are exactly the same, the 10G version is named SFP10G or SFP+ (Enhanced Small Form-factor Pluggable) The SFP provides a compact solution with the same functionality as the older form-factors.

Transceiver Form-Factors

There are various form-factors available above 10G, such as the QSFP (Quad Small Form-factor Pluggable) for 40G (and QSFP28 for 100G) and CFP.  The 'C Form-factor Pluggable' is seen in three different shapes, CFP, CFP2, CFP4. Over time the size of the CFP was reduced twice by a scale factor of two, which resulted in the CFP4.

Optical Transceivers have different specification for different needs. They can differ in speed from 100mbit to 100G. They can also differ in strength measured in dB power budget from 10dB to 41dB. Futhermore, they are also available in different light colors used in the multiplexing technique like CWDM and DWDM. There are 1000 and 1000 different versions of optical transceivers. Most Router and Switch hardware producers are focusing on just a fraction of what is available. Solid Optics can provide you all the different modular optics for all the various brands like Cisco, Juniper, HP, Dell, Brocade, Arista, Alcatel-Lucent and much more.
