The HT-400G-QDD-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.
400G AOC线缆是一种高速光纤连接器，可以用于传输距离为1-100米的400G以太网中。它采用了QSFP-DD封装形式，每个端口包含4个发送和4个接收通道，共计8个通道，每个通道传输速率为50Gbps，总传输速率为400Gbps。与传统的100G AOC线缆相比，400G AOC线缆具有更高的传输速率和更大的带宽，可以满足更高速率的数据传输需求。
