SN Patch cord

The SN® connector is a new duplex fiber optic connector optimized for 400G data centers. SN® connectors are a more efficient, reliable and cost effective alternative to MPO connectors. SN® has two LC 1.25 mm OD zirconia ferrules in one housing with a 3.1 mm spacing, compared to 6.25 mm for duplex LC connectors. Each SN® connector ferrule can be individually prepared, polished and tested, allowing manufacturers to easily control each fiber connection of the connector. In addition, the use of widely deployed 1.25 mm ferrules allows for a simpler manufacturing process that is already streamlined. In contrast, MPO connectors are manufactured with all 12 fibers terminated in a single MT ferrule. All 12 fibers are prepared, polished and tested simultaneously, which can result in different performance for each fiber connection. Since SN® uses the same zirconia ferrule as the duplex LC, the entire end face can be easily cleaned with conventional cleaning methods.
