What types of SFP transceivers are there?
Aug 16, 2018

FP transceivers come in a variety of different transmit and receive types, and users can select the appropriate transceiver for each link to provide "optical performance" based on the type of fiber available, such as multimode fiber or single mode fiber. Available optical SFP modules are generally classified into the following categories: MMF (SX) at 850 nm wavelength / 550 m distance, SMF (LX) at 1310 nm wavelength / 10 km distance, XD at 1550 nm wavelength / 40 km distance, 80 km distance ZX, EX or EZX at a distance of 120 km, and DWDM. The SFP transceiver also provides a copper interface so that host devices designed primarily for fiber optic communications can also communicate over UTP network cables. There are also wavelength division multiplexing (CWDM) and single fiber "two-way" (1310/1490 nm wavelength up/down) SFP.

Commercial SFP transceivers are capable of delivering rates up to 4.25 G bps. Several packages of 10 Gbps transceivers are available in XFP and a new variant "SFP+" that is basically identical to the SFP package.
