Product introduction

400G QSFP56 DD SR8 is a Eight-Channel, Pluggable, Parallel, Double Density for 2×200 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnection applications. It integrates eight data lanes in each direction with 8×26.5625GBd. Each lane can operate at 53.125Gbps up to 70 m using OM3 fiber or 100 m using OM4 fiber with FEC. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 76 contact edge type connector. The optical interface uses a MPO16/MTP16 APC connector . The Common Management Interface Specification (CMIS) for QSFP DD modules.
