Technical features: 51201557-150 supports the remote terminal function, which can terminate a single fiber cable using a second fiber coupler module at the remote I/O processing card file. In addition, it supports a full-duplex link configuration, allowing simultaneous sending and receiving.

Compatibility: This module allows mixing of standard and long distance I/O Link Extenders in A subsystem, but both ends of the “A” and “B” links must be of the same type.

Connectivity: 51201557-150 uses ST connectors for fiber optic cable connections, and a pair of ST connectors is required for each endpoint of each fiber optic link to achieve a full-duplex configuration.
