Optical modules are divided by package

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

2. Small pluggable transceiver module (SFP), currently the most widely used.

3.GigacBiDi series single-fiber bidirectional optical modules use WDM technology to realize bidirectional information signal transmission over a single fiber (point-to-point transmission. Especially when fiber resources are insufficient, one fiber is required to transmit bidirectional signals). GigacBiDi includes SFP single-fiber bidirectional (BiDi), GBIC single-fiber bidirectional (BiDi), SFP+ single-fiber bidirectional (BiDi), XFP single-fiber bidirectional (BiDi), SFF single-fiber bidirectional (BiDi) and so on.

4. RJ45 electrical port small pluggable module, also known as electrical module or electrical port module.

5.SFF is divided into 2x5, 2x10, etc. according to its pins

6. Gigabit Ethernet Interface Converter (GBIC) module

7. Passive optical network PON (A-PON, G-PON, GE-PON) optical module

8.40Gbs high-speed optical module.

9.SDH transmission module (OC3, OC12, OC48)

10. Storage modules, such as 4G, 8G, etc.
