The Gigalight GQM-SPO101-IR4C is a four-channel, pluggable, parallel, fiber-optic QSFP28 transceiver for 100G Ethernet PSM4 and InfiniBand DDR/EDR applications. This transceiver is a high performance module for data communication and interconnect applications. It integrates four data lanes in each direction with 103Gbps bandwidth. Each lane can operate at 25.78Gb/s up to 2km over G.652 SMF. This module is designed to operate over single-mode fiber systems using a nominal wavelength of 1310nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses a 12-fiber MTP/MPO connector. This module incorporates Gigalight proven circuit and optical technology to provide reliable long life, high performance, and consistent service.
