Carry a single-mode optical connection between LC-equipped network endpoints with a 15 ft duplex patch cable built around 9 µm fiber. The yellow PVC-jacketed construction provides two fiber paths in one 2.0 mm cable, terminating in LC connectors at both ends. This configuration suits cross-connects, patch panels, optical transceivers, and network equipment that require an LC-to-LC single-mode jumper. Legrand 810-LL7-015FTHK supplies a fixed-length connection for short fiber links where preterminated connectors avoid field connector work. Duplex construction supports paired optical paths in one cable, helping keep transmit and receive connections together between active equipment and a fiber distribution point. The LC connector format fits high-density fiber interfaces commonly used on network hardware and patching systems. Within the 810-LL7 cable designation, this version is distinguished by its 15 ft length, duplex 9 µm fiber construction, LC-to-LC termination, and yellow PVC jacket. TAA compliance makes the cable suitable where that sourcing requirement applies. Match connector type, fiber type, cable length, and jacket requirements to the installed optical link before selection.
