- 3 m fiber-optic cable for communication between paired 1757-SRM modules
- Keyed ST-type connectors with 62.5/125 µm multimode optical fiber
- One transmit-and-receive fiber channel for the redundancy link
1757-SRC3 is an Allen-Bradley 3 m fiber-optic cable specified for communication between two 1757-SRM modules in a redundant chassis pair.
The documented 3 m length supports layouts that require more routing distance than 1757-SRC1 while retaining the same keyed optical connection and single transmit-and-receive channel.
Before installation, measure the complete cable path, remove the protective hardware in the documented sequence, seat both connectors fully, and protect the route from sharp bends, cutting, traffic, and abrasion.
Availability, condition, price, and shipping time for 1757-SRC3 are confirmed during quotation.

- Rockwell Automation identifies 1757-SRC3 as the 3 m cable option
- Measure the complete protected path between both 1757-SRM modules before ordering
- Use the documented 3 m option when the 1 m cable cannot complete the route safely
- 1757-SRC3 terminates at the optical connectors on the two 1757-SRM modules
- The ST-type cable and module connectors are keyed for correct installation
- The cable provides one transmit-and-receive optical channel across the chassis pair
- Plan the 3 m route without sharp bends in the optical fiber
- Keep the longer cable path away from cutting, crushing, and traffic hazards
- Protect the connector ends from contamination until the documented connection step
- Separated redundant chassis pairs that require the documented 3 m cable length
- Exact replacement of an installed Allen-Bradley 1757-SRC3
- Protected optical redundancy links where the 1 m catalog option is too short
