Enable Seamless Connectivity for Your Network
Network-Switch.com offers the ability to configure the pre-set compatibility of either connector of the AOC cable online with NS BOX to connect Cisco to Arista, Dell to Juniper, and any other mixes of configurations.
Overview
The NS 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 μm 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 1×800G-to-4×400G 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.

Why Choose NS MPO 12F to 2xMPO 4F APC Low Loss Breakout Cables?
-
Optimized for 400G/800G SR fanout – Ideal for linking 800G twin-port OSFP transceivers to multiple 400G OSFP/QSFP112 SR optics.
-
Efficient 4-to-2 channel splitter design – Uses 8 active fibers with 4 inactive fibers as strength members for robust deployment.
-
Lower loss vs. cassette-based solutions – Direct MPO breakout reduces interconnect points and overall insertion loss.
-
High return-loss APC performance – 8° angled APC endfaces minimize back reflections for cleaner multimode signals.
-
Bend-insensitive OM3 fiber – Maintains optical performance in tight routing common in dense racks and pathways.
-
Riser-rated OFNR construction – Suitable for in-cabinet routing and structured cabling in large cloud and enterprise data centers.
Length Options
Standard stocked lengths:
Available in common breakout lengths tailored for short-reach 400G/800G patching between switches and transceivers within and between racks.
Custom lengths:
Custom trunk lengths, breakout leg lengths, labeling, and configurations are available on request to match your panel layouts, trunk routing, and optics locations.
