Connect equipment with FC and LC fiber interfaces across a 30 ft run using the Legrand 810-LL7-030FTHK duplex single-mode patch cable. Its two fiber paths provide the paired connection arrangement used for separate transmit and receive paths, while FC-to-LC termination addresses mixed connector interfaces. The yellow cable jacket makes this single-mode run readily distinguishable in structured cabling areas. This configuration uses 9 µm fiber in a 2.0 mm duplex construction with a PVC outer jacket. It is a terminated patch cable rather than an adapter or bulk cable: one end has an FC connector and the other has an LC connector. Choose this connector combination when installed equipment, fiber panels, or existing patch fields require FC at one endpoint and LC at the other. Model 810-LL7 identifies the cable configuration, including its duplex construction, 30 ft length, FC-to-LC ends, and yellow PVC jacket. The 2.0 mm cable profile provides a compact patching option for telecommunications rooms, equipment cabinets, and fiber cross-connect areas. Confirm the connector interfaces at both endpoints and the required cable route length before installation, especially where existing single-mode patching uses different connector families.
