ATOP’s 200G QSFP56 SR4 transceiver is an integrated module with micro-optic and semiconductor components, facilitating optical-electrical and electrical-optical conversions. Designed as a four-channel, pluggable, parallel QSFP56 transceiver for 200Gbps fiber communication, each channel can operate at 53Gbps up to 100m on OM4 fiber with an operating wavelength of 850nm. The optical interface uses a 12-fiber MTP(MPO) connector, and the electrical interface employs a 38-contact edge-type connector. This 200G SR4 module complies with the 200GBASE-SR4 standard of IEEE802.3cd, providing reliable, long-life, high-performance, and consistent service.
