The 400G QSFP112 AOC is a Four-Channel, Pluggable,Parallel for 400 Gigabit Ethernet Applications. This AOC is a high performance module for short-range multi-lane data communication and interconnection applications. It integrates four data lanes in each direction with 4×53.125GBd. Each lane can operate at 106.25Gbps up to 100m using OM4 fiber with FEC. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The Common Management Interface Specification (CMIS) for QSFP modules.
