Configuration
The RJ-45 connectors support multiple insertions and removals with an estimated service life expectancy of 200
insertion/removal cycles. Connector components are exposed to torsion forces across any axis of the connector and tension
forces that are static from cable weight and cable dressing. Dynamic stresses are imposed on the connectors from transients in
assembled system transport to the plant site and operation in a high vibration power production environment. Connector
design anticipated static forces of three pounds force (89.9 Newton) per connection while complying with the other dynamic
operating load requirements.

†
Single Mode Fiber (SMF) requires the additional IR SFP single-mode transducer, GE part # 65G2100–008.
†
A port adapter is used if needing to interface an existing SC fiber termination to the LC fiber port.
GE part # 336A5026P01 SC to LC adapter is required for multi-mode fiber (most common).
GE part # 336A5026P02 SC to LC adapter is required for single-mode fiber.
