12 Fiber MPO/UPC Low Loss Female to Female - Multimode OM4 - Plenum (OFNP) - Method A

This 12-fiber MPO patch cable is built for parallel optic structured cabling deployments running OM4 multimode fiber. It is a laser-optimized 50/125µm multimode fiber, suited for extended-reach high-speed links. This MPO connector uses UPC polish, a 0-degree endface with a slight convex curvature that gives clean physical contact between mated fibers, making it the standard choice for typical Ethernet and multimode data center connections. The female-to-female configuration provides unpinned connectors on both ends, used where the mating adapter or equipment interface supplies the guide pins. Method A maintains straight-through fiber mapping in a key-up to key-down orientation, where each fiber position at the near end arrives at the same position at the far end, specified when the cabling system requires direct fiber continuity without position reversal. The aqua jacket is listed Type OFNP under NEC Article 770, suitable for installation in ducts, plenums, and other air-handling spaces. The low-loss ferrule meets a maximum insertion loss of ≤0.35 dB, suited for high-channel-count and loss-budget-sensitive deployments.
