LC UPC to ST UPC Fiber Patch Cord for OS2 Single-Mode Simplex Links

This LC UPC to ST UPC Fiber Patch Cord provides a single-fiber connection between equipment with an LC/UPC interface and equipment with an ST/UPC interface. Both ends use UPC-polished connectors, while the LC and ST connector bodies require their respective matching ports or adapters. The OS2 9/125µm single-mode cable is intended for compatible indoor optical interconnections.

The LSZH-jacketed 2.0mm cable is offered in five purchasable lengths: 1m, 2m, 3m, 5m and 10m. Select the length based on the installation route and confirm that both endpoints accept the specified connector and polish types. UPC connectors should not be directly mated with APC connectors.

OS2 Simplex for Single-Mode Patching

One OS2 9/125µm single-mode fiber supports a compatible single-fiber optical connection. Both mating interfaces and the link’s wavelength requirements must match the connected equipment.

LSZH Jacket and Five Length Options

Choose from 1m, 2m, 3m, 5m and 10m. The 2.0mm jacketed construction is intended for indoor patching; confirm bend and routing requirements for the actual installation.
