The INTCERA 4x32G QSFP28 850nm 100m optical transceiver (GQS-MPO111-SR4CL) is a four-channel, pluggable, parallel, fiber-optic QSFP28 module for 100- or 40-Gigabit Ethernet, InfiniBand FDR/EDR and 128G (4x32G) applications. This transceiver is a high-performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 112.2Gbps bandwidth. Each lane can operate at 28.05Gbps up to 70m using OM3 fiber or 100m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38-contact edge type connector. The optical interface uses an 12-fiber MTP/MPO connector. This module incorporates INTCERA proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
