GLsun QSFP-100G-SR4 Optical Transceiver is an integrated transceiver module containing a micro-optic component and semiconductor material, and can implement optical-electrical conversion and electrical-optical conversion. The module is designed as a four-channel, pluggable, parallel, QSFP28 transceiver for 100Gbps fiber-communication. Each channel can operate at 25Gbps up to 70m on OM3 fiber. And the operating wavelength is 850nm. The optical interface uses an 12 fiber MTP(MPO) connector, and the electrical interface uses a 38 contact edge type connector. This product is compliant to 100GBASE-SR4 of IEEE802.3bm standard and SFF-8436 specification, and provides reliable long life, high performance, and consistent service.
