1. The power port module, the interface type is the RJ45 interface, transmitted 100 meters. Connecting super five types of network cables.

　　2. Light port module: The common interface type is the LC interface. That is a mini -type, small GBIC interface. Type SC port, optical fiber jump line or tail fiber connected to the LC head.

　　The LC interface is divided into single -port LC and double -port LC, which are used for single fiber and double fiber SFP light modules. The transmission distance is within 120 kilometers.

　　SFP light module identification method:

　　There is a small handle on the SFP. For GE's SFP light module:

　　Black: multi -mode MM SX module

　　Blue: single -mode SM LX module

　　Light yellow: single -mode SM LH OR ZX module

　　For the 2.5G SFP light module:

　　Gray: single -mode SM SR module

　　Green: single -mode SM LR module
