400G QSFP-DD SR8 is an eight-channel, pluggable, parallel, fiber-optic QSFP 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 meters using OM3 fiber or 100 meters using OM4 fiber with FEC. This module is 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 an MTP24/MPO24 PC connector or MPO16/MTP16 APC connector. The Common Management Interface Specification (CMIS) for QSFP-DD modules, This module incorporates proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
