400G QSFP-DD AOC

 The TSQS-852HG-XXXC is an Eight-Channel, Pluggable, Parallel, Fiber-Optic QSFP Double Density for 2x200 Gigabit Ethernet Applications. This AOC is a high performance module for short-range multi-lane data communication and interconnect applications. It integrates eight data lanes in each direction with 8x26.5625GBd. 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.
