1. Definition
The packaging method of the SFP light module is that the hot insertion is unplugged, and the maximum rate can now reach 10g, and the LC interface is mostly. The abbreviation of SFP is Small Form-Factor Pluggable, which can be briefly understood as GBIC's promotion version. The size of the SFP light module is reduced by half than the GBIC light module, and the number of ports that can be more than doubled on the same panel can be equipped with the same panel.
2. Composition
The SFP optical module consists of laser, line board IC and external accessories. The external accessories contain cases, unlocking parts, buckle, base, pull ring, rubber plug, PCBA, and the color of the ring can help the parameter type of the different module.
3. Open the SFP light module
GBIC and SFF are gradually replaced by the SFP light module with the agility of the network in the optical module. It is opening in the direction of miniaturization and hot insertion. The SFP optical module inherits GBIC's hot insertion characteristics, and also learns the advantages of SFF miniaturization. The choice of LC heads has greatly increased the port density of network devices, used to the rapid opening trend of the network, and obtained the most wide range of use. Although many higher skills and updated optical modules have now been presented, the SFP light module will continue for a long time. After the SFP, the opening of the optical module is mainly opened towards a higher speed. Now 10G, 40G, 100G and other light modules have been presented.
