Connect LC-terminated fiber interfaces over a 40 ft run using the Legrand 810-LL7-040FTHK duplex fiber cable. This configuration combines 9 µm fiber with LC connectors at both ends, providing a matched LC-to-LC connection for optical patching. The duplex construction carries two fiber paths within one cable assembly, helping maintain an orderly paired connection between compatible equipment ports, panels, or enclosures. The yellow 2.0 mm PVC jacket makes the cable’s physical configuration easy to identify during installation and servicing. Its 40 ft length suits connections that need more reach than a short equipment patch cord while remaining within a single room, rack row, telecommunications space, or equipment area. LC connectors provide a compact interface for fiber ports and adapters that use the LC connector format. Within the 810-LL7 cable family, this version is defined by its 40 ft length, duplex construction, 9 µm fiber, LC-to-LC termination, yellow PVC jacket, and 2.0 mm cable diameter. It is also specified as TAA compliant. Select this cable when the installed path requires those exact connector, fiber, length, and jacket characteristics rather than a different termination or cable construction.
