MPO Single Mode 40G Fiber Patch Cable 12 Cores UPC Type B 3m | 40G high-speed transmission, MPO female Type B Sequence, 0.3dB Insertion Loss, For Data Center FTHH

This MPO single-mode fiber optic patch cord is recommended for data center infrastructure engineers, high-density cabling integrators, enterprise core network operators, and 40G network upgrade technicians.
It addresses key pain points: scattered single-core patch cords occupying rack space, incorrect polarity causing 40G link failures, extended deployment cycles due to field splicing, and low cabling efficiency in high-density fiber optic systems. This is a factory-pre-terminated MPO mother-to-mother backbone patch cord with Type B crossover polarity, compliant with TIA industry standards. It supports parallel transmission of up to 40G Ethernet over 8 or 12 single-mode fibers and is perfectly compatible with QSFP+ optical modules and high-density MPO patch panels. One MPO patch cord can replace 8 or 12 traditional single-core patch cords, significantly reducing cabling within the rack and increasing rack space utilization by over 60%. This product offers two endface options: APC and UPC. The 8° tilt angle APC polished endface provides 60dB of return loss, ideal for long-distance transmission, PON, and CATV applications; the UPC polished endface offers lower insertion loss and is suitable for general data center interconnects. Utilizing OS2-grade single-mode fiber, this product operates stably at wavelengths of 1310nm and 1550nm, with an insertion loss of 0.3 dB per connector, providing consistently low-attenuation performance for short- and medium-distance data center links. Six length options (1 meter to 20 meters) cover all common indoor data center applications: top-to-bottom rack connections, inter-rack backbone links, patch panel interconnects, and data center expansion. The standard yellow OS2 sheath conforms to data center color coding standards for easy fiber type identification, and its bend-resistant construction is suitable for compact rack cabling. This product is widely used in 40G data center backbone cabling, high-density fiber distribution systems, cloud computing room deployments, enterprise core network upgrades, and IDC data center expansion projects. All products are brand new and have undergone factory testing to ensure correct insertion loss, return loss, polarity, and end-face quality. Due to manual cutting, there may be a 1%-5% error in length, but this will not affect normal installation and transmission performance.
