The Optical Transceiver 200G QSFP56 SR4 is designed to deliver high-speed, short-reach optical connectivity for modern data center environments. Supporting four 53.125Gbps PAM4 channels and operating at an 850nm wavelength, this transceiver enables efficient 200G Ethernet transmission over multimode fiber using parallel optics.
Built with VCSEL transmitters and PIN receivers, the QSFP56 SR4 module provides stable optical performance and reliable signal integrity in high-density deployments. Featuring an MPO-12 connector, it supports transmission distances of up to 70 meters on OM3 and up to 100 meters on OM4 fiber. With a compact QSFP56 form factor, compliance with SFF-8636, commercial temperature operation, and a maximum power consumption of 5W, this transceiver is well suited for scalable, production-ready data center architectures.
