NSComm MPO 12F to 2xMPO 4F APC Breakout Cables, 8 Fibers, Multimode (OM3), OFNR, Low Loss, Polarity Type B
Overview
The NSComm MPO 12F to 2xMPO 4F APC low loss breakout cable is a high-density OM3 multimode fanout solution designed for 400G/800G data center architectures. With one 12-fiber MPO-12 APC (Female) trunk breaking out to two 4-fiber MPO-4 APC (Female) legs, this assembly provides a 4-channel-to-two 2-channel splitter design that uses 8 active fibers for transmission and 4 inactive fibers as additional strength members. The APC endfaces feature an 8-degree angled polish to help deflect internal back reflections away from the transceiver, preserving signal quality in high-speed multimode links.
Engineered with bend-insensitive OM3 50/125 ÎĽm multimode fiber and a riser-rated OFNR jacket, this Type B breakout cable is ideal for short-reach, high-bandwidth parallel optics deployments. When deployed in pairs, two MPO-12 to 2x MPO-4 APC breakout cables can link an 800G NVIDIA InfiniBand twin-port OSFP transceiver to four 400G NVIDIA InfiniBand OSFP/QSFP112 transceivers, enabling efficient 1Ă—800G-to-4Ă—400G fanout in high-speed multimode links. With 400G transceivers, only two channels are activated per leg, effectively creating 200G links. Compared with separate breakout cassettes, MPO breakout cables reduce the number of interconnects, lowering overall insertion loss and total cost.
