The PLC 1757-SRC1 cable is a 10-meter (32. It is a special type of multi-mode fiber-optic cable with 62.5/125 micron and a wavelength of 1300 nm. This 1757-SRC10 redundancy module cable comes factory-assembled with type ST-type (fiber-optic) connectors on each end that are specifically designed for plugging into the 1757-SRM redundancy module ports. The ST-type (fiber-optic) connectors on the 1757-SRC1 redundancy module cable and in the 1757-SRM module are keyed for easy and correct installation.
The PLC 1757-SRC1 redundancy module cable does not need any type of ground isolation because it is a fiber-optic interface. It uses only one fiber-optic channel for transmitting and receiving information between the primary and secondary PLCs. Installing and configuring the redundancy feature in PLC PLC systems is a task that should only be performed by highly trained electrical personnel. It is important to remember that the 1757-SRC1 redundancy module cable should not be bent around sharp edges, and that it should not be cut, run over, abraded, or otherwise damaged during installation. The total light loss through the cable needs to be less than or equal to 7 dB at 1300 nm wavelength for the redundancy system to work properly.
