MTP and MPO to 4× LC breakout assemblies provide high density optical fanout connectivity for switches, servers, and aggregation hardware. These cables support 10 Gb per second operation across OM3 50/125 micron multimode fiber, delivering stable bandwidth and low latency for short reach environments. Breakout designs convert a single MTP or MPO trunk into four LC duplex channels for flexible distribution in structured cabling systems. Assemblies are engineered for low insertion loss, reliable optical performance, and dependable operation in professional data center fiber installations.
