Senko Advanced Components’ SN connector is a duplex optical fiber connector designed for data center 400G optimization. The SN has two LC-style 1.25-mm O.D. Zirconia ferrules in a single housing, pitched 3.1 mm apart versus 6.25 mm in a LC duplex. The SN connector allows users to have four connectors (eight fibers) in one transceiver.
Judge’s comment: “The SN connector is an important component for future 400G break-out applications, allowing four duplex connections in a QSFP-DD/OSFP footprint without using a separate fan-out or patch panel.”
