Product Presentation

This 12-Fiber MPO OS2 Singlemode Harness Cable is an essential high-performance solution for simplifying fiber management and accelerating deployment across data center racks. It is the perfect choice for high-speed network migrations, directly facilitating connections in 10G to 40G and 25G to 100G systems, and acting as a streamlined Alternative to the MPO Jumper + MPO Cassette combination. The assembly transitions from the single MPO APC (Female/Male) trunk to LC APC connectors. It delivers reliable, Elite Low Loss performance with an IL Max of ≤ 0.35dB (RL ≥ 60dB), backed by certified Corning/YOFC fiber and supporting Type A/AF/B/U Polarity.
