Both adapter ends are LC receptacles, so this coupler joins two LC-terminated patch cords or connects a patch cord to a bulkhead. The duplex configuration carries two fibers per connection, used for separate transmit and receive paths in bidirectional links. It mounts via snap-in into a panel cutout, requiring no hardware for installation in patch panels, wall boxes, or equipment enclosures. The blue thermoplastic housing is rated UL94 V-0, meeting the flame resistance requirement for rack-mounted telecom and datacom gear. Ceramic ferrules inside the adapter align the fiber cores with the precision needed for singlemode insertion loss budgets. Dust caps are included on both ports, protecting the polished ferrule endfaces from contamination when the coupler is not mated. For singlemode systems, even microscopic dust on the fiber endface can scatter light and raise insertion loss, so the caps are a practical inclusion for field installation and storage. ## Where This Coupler Fits in a Fiber Plant This coupler is a straight-through adapter — it does not convert between connector types or split/combine optical signals. Its job is to align two LC ferrules end-to-end in a controlled mating sleeve. Singlemode operation means it is designed for 9/125 µm fiber systems used in long-haul, metro, and enterprise backbone links, where the core diameter is small and alignment tolerances are tight. The duplex format matches standard LC patch cords used in SFP/SFP+ transceiver panels. In a typical deployment, one side receives the trunk cable from the patch panel, and the other side connects the equipment jumper. The snap-in panel mount keeps the coupler fixed in the cutout while patch cords are plugged and unplugged repeatedly.","metaTitle":"TE Connectivity 2-6457567-2 LC Duplex Singlemode Coupler","metaDescription":"TE Connectivity 2-6457567-2 LC duplex singlemode fiber coupler.
