KOCENT OPTEC
1 / 3
The QSFP56 200G SR4 Fiber Optic Module supports 200GE links and up to two 100GBASE-SR2 breakout links or four 50GBASE-SR lengths of up to 100m over OM4 MMF. The module features four pairs of Multi-Mode Fiber with an MPO-12 UPC connector. It is fully compliant with the IEEE 802.3bm protocol and 200GAUI-4/CEI-56G-VSR-PAM4 standards.
The 200 Gigabit Ethernet signal is transmitted over four parallel pairs of fibers at a nominal wavelength of 850nm at 50Gbps per fiber. This versatile module can also be utilized as a 2x100GE breakout to 100GBASE-SR2 modules. Forward Error Correction (FEC) is managed on the host platform. These high-performance, cost-effective I/O solutions are ideal for LAN, HPC, and SAN environments, meeting and exceeding InfiniBand HDR and temperature requirements for maximum reliability.
