SN 1.6 mm and 2.0 mm

SN-New-Boot-quad-flyer 437-1-1

The SN® connector combines ‘best-in-class’ packing density with carrier-grade performance and reliability. Designed and optimized for next-generation data rates, the SN connector offers network operators the chance to densify their existing legacy infrastructure whilst at the same time providing an upgrade path to 400G and beyond. The SN Standard connector is suitable for termination to either 1.6 mm or 2.0 mm round cable that incorporates a ruggedized jacket and internal strain relief.
