- 1 m fiber-optic cable for communication between two 1757-SRM redundancy modules
- Keyed ST-type connectors with 62.5/125 µm multimode optical fiber
- One transmit-and-receive fiber channel with no electrical ground-isolation requirement
1757-SRC1 is an Allen-Bradley 1 m fiber-optic cable specified for communication between two 1757-SRM modules in a redundant chassis pair.
Rockwell Automation identifies it as the shortest cable in the documented 1757-SRC range, making it suitable when the complete protected route between the two modules fits within 1 m.
Before installation, verify both module endpoints, remove the protective plug and cable-end caps, seat the keyed connectors fully, and route the optical cable without sharp bends, cutting, traffic, or abrasion.
Availability, condition, price, and shipping time for 1757-SRC1 are confirmed during quotation.

- Rockwell Automation identifies 1757-SRC1 as the 1 m cable option
- The complete protected path between both 1757-SRM modules must fit within that length
- Use another documented 1757-SRC length when the planned route cannot be completed safely within 1 m
- Open the first 1757-SRM door and remove its black protective plug
- Remove the protective caps from the cable ends before seating the keyed ST connectors
- Connect both modules and close each redundancy-module door after the connector is seated
- Avoid sharp bends because 1757-SRC1 contains optical fibers
- Route the 1 m cable where it cannot be cut or run over
- Reject or investigate any cable showing abrasion or other physical damage
- Closely positioned redundant chassis pairs whose protected route fits the documented 1 m length
- Exact-catalog replacement of an installed 1757-SRC1 redundancy cable
- Single-channel optical communication between paired 1757-SRM modules
