By Function

Including optical receiver module, optical transmitter module, optical transceiver module and optical transponder modules.

Integrated optical transceiver module main function is to achieve optical / electro-optical conversion, including optical power control, modulation transmission, signal detection, IV conversion, and limiting amplifier decision regeneration, in addition to the security information inquiry, TX-disable features such as common There SFP, SFF, SFP+, GBIC, XFP, 1x9 and so on.

In addition to the optical transponder module having a photoelectric conversion function, it also integrates a number of signal processing functions, such as: MUX/DEMUX, CDR, function control, sexual energy acquisition and monitoring. Common optical transponder modules are: 200 / 300pin, XENPAK, and X2/XPAK like.

Optical transceiver module, referred to as the optical module or fiber-optic modules, optical fiber communication system is an important device.

Parametric classification

Pluggable: Hot-swap and non-hot plug

Package: SFP, GBIC, XFP, Xenpak, X2,1X9, SFF, 200 / 3000pin, XPAK

Transmission rate: transmission rate refers to the number of bits transmitted per second, the unit Mb/s or Gb/s. Optical modules covers the following main rate: low rates, Fast, Gigabit, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G and 40G.

By Package Category

1.XFP (10 Gigabit Small Form Factor Pluggable) is a hot-swappable, protocol-independent optical transceiver for 10G Ethernet, SONET/SDH optical fiber channel.

2. The small form factor pluggable optical transceiver module (SFP), currently the most promising.

3.GigacBiDi series single-fiber bidirectional optical module makes use of WDM technology to achieve a single fiber bidirectional transmission of information number (point to point transmission, especially lack of fiber resources, need a two-way optical fiber transmission signal). GigacBiDi including SFP Bidirectional (BiDi), GBIC Bidirectional (BiDi), SFP+ Bidirectional (BiDi), XFP Bidirectional (BiDi), SFF Bidirectional (BiDi) and so on.

4.RJ45 electrical port small form factor pluggable module, also known as electrical module or electrical interface modules.
