The Fiberstamp Technologies FEG-100S4M30C is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP28 SR4 for 100 or 40 Gigabit Ethernet and Infiniband FDR/EDR Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnect applications. Each lane can operate at 25.78125Gbps up to 70 m using OM3 fiber 100m using OM4 fiber w/o FEC or 300m OM4 MMF with KR-FEC. 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 Fiberstamp Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
