SFP optical modules are increasingly receiving high attention in communication work. SFP optical modules are one of the highly anticipated modules. Below, we summarize the basic knowledge of SFP optical modules from multiple levels, hoping to provide you with necessary help.

1. Definition of SFP optical modules

The packaging method for SFP optical modules is hot swappable small packaging, and now the maximum speed can reach 10G with many LC ports. The abbreviation of SFP is Small Form factor Pluggable, which can be simply understood as the promotion category of GBIC. The volume of SFP optical modules is reduced by half compared to GBIC optical modules, allowing for more than twice the total number of port numbers for weapons and equipment on the same control panel.

2. SFP optical module composition

The SFP optical module consists of a laser generator, PCB circuit board IC, and external components. The external components include a casing, opening parts, locks, base, pull rings, rubber plugs, PCBA, and the color of the pull rings can help you distinguish the main parameter types of the module.

3. Flipping the SFP optical module

The GBIC and SFF optical modules are gradually replaced by SFP optical modules, following the ingenious opening of the Internet. It is flipping towards miniaturization and hot swapping. The SFP optical module inherits the hot swappable characteristics of GBIC and also learns the advantages of SFF miniaturization. The adoption of LC head has greatly improved the relative density of the port number of computer equipment, used to the rapid development trend of the Internet, and obtained the most extensive application. Despite the emergence of many higher skilled talents and upgraded optical module products, SFP optical modules will continue to exist for a long time. In SFP, the flipping of optical modules is mainly towards higher speed transmission, and now it has shown 10G, 40G, 100G,200G,400G,800G and other optical modules.
