MPO OM4 to 12-Fiber to 6-LC Duplex Breakout Cable — Type B Breakout Cable Multi-Mode Fiber Breakout Cable • Available in 3 m, 5 m, 7 m, 10 m, 15 m, and 20 m This MPO OM4 to 6-LC duplex breakout cable series is designed for high-density fiber patching in data centers and structured cabling environments where clean routing, fast deployment, and space savings matter. Featuring an MPO female connector on one end and six LC duplex legs on the other, these breakout assemblies are ideal for direct connection to optics, cassette transitions, and high-bandwidth switch or server applications using OM4 50/125 multimode fiber. Multiple lengths are available to support short cross-connects, cabinet runs, and longer in-rack or row-to-row routing needs. Why these cables matter High-density MPO breakout design — Transitions a 12-fiber MPO connection into 6 LC duplex channels for efficient patching. Optimized for high-speed optics — Suitable for 40G QSFP SR4 / CSR4 and 100G QSFP28 SR4 connectivity. OM4 laser-optimized multimode fiber — Supports modern data center bandwidth requirements with excellent optical performance. Type B polarity — Ideal for applications requiring reversed fiber mapping in MPO environments. Multiple stocked lengths — Makes it easier to match cable length to cabinet layout and reduce slack. Slim 3.0 mm jacket — Helps improve cable routing and organization in dense rack and cabinet installations.
