RJ50
Ethernet cables (RJ50) are available in two versions - normal (terminated with connectors at both ends) and pigtail (connector on one end only) - and can be supplied in various lengths.
Normal
Cable assembly overview
For Ethernet cables with RJ50 connectors at both ends, the assembly consists of three parts:
Connector A: RJ50 plug, 10-pin male. Connects to the MRU.
Connector B: RJ50 plug, 10-pin male. Connects to the system output.
Cable (C): Round stranded Cat5e/6 cable or 10-conductor stranded round cable.
