SM 12 cores MPO Female to 6x LC Duplex harness Cables assemblies
SM 12 cores MPO Female to 6x LC Duplex harness Cables assemblies.
The SM 12-Core MPO-LC Harness Cable is a high-density breakout assembly designed for precision optical transmission. One end features a single 12-fiber MPO connector(Male or Female), compliant with IEC-61754-7 standards. This trunk breaks out into 6 individual LC Duplex or LC uniboot or 12 LC SimplexConnector allowing connection to standard transceivers.
The cable utilizes OS2 Single-mode fiber (9/125μm), optimized for long-distance data transmission. It typically employs 2.0mm or 0.9mm round PVC/LSZH jacketed breakout legs for durability and flexibility, while the MPO trunk often uses a 2.0mm or 3.0mm jacket.

Application
This harness cable is essential for bridging high-density backbone infrastructure with active equipment. Its primary application is in Data Centers and Telecommunication rooms, serving as a transition point between MPO-based Main Distribution Areas (MDA) and LC-based Hardware Distribution Areas (HDA).
It is widely used to connect 40G/100G MPO uplinks on core switches to 10G SFP+ LC ports on servers or patch panels. By converting a single high-density MPO interface into six standard LC channels, it simplifies cable management, reduces rack congestion, and accelerates deployment in enterprise networks, FTTH backbones, and CATV systems.
