The TSD4Q-85M-XXXD is an 8-Channel, Pluggable, Parallel, Fiber-Optic 400G QSFP56-DD to 4 x 100G QSFP56 AOC. It integrates 8 data lanes in each direction at QSFP-DD end and 2 data lanes in each direction at QSFP end. 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 contacts edge type connector at QSFP-DD end and 38 contacts edge type connectors at QSFP end.
