MPO to LC harness cable is a specialized MPO-to-LC breakout patch cord designed for internal connectivity within MPO cassette modules and compact modular fiber enclosures.
Distinguished from standard rack-to-rack MPO breakout cables, this harness cable is optimized for short-distance internal routing. It is constructed with Ø0.9mm breakout legs and a male MPO connector with guide pins, allowing neat and space-saving fiber management in high-density cassette applications where space constraints, bending performance and cable congestion are critical.
This product is widely applied in data centers, ODF/FDF modular frames, MPO cassette systems and high-density fiber distribution networks. It supports parallel-to-duplex fiber conversion for 40G, 100G and 400G optical transmission architectures.
