Description
The 400GBASE-LR8 QSFP-DD features eight LWDM channels: 1273, 1277, 1282, 1286, 1295, 1300, 1304, and 1309 nm, each operating at 53.125 Gbps (PAM4), for a total bandwidth of up to 425 Gbps. It uses a duplex LC connector and can transmit over parallel single-mode fiber for distances up to 10 kilometers.
Veivot's VV-QDD-LR8 complies with the IEEE 802.3bs protocol and the 400GAUI-8/CEI-56G-VSR-PAM4 standards. Furthermore, the 400G LR8 is based on PAM4 modulation technology, QSFP-DD packaging, and DSP chip design. With these features, this 400G QSFP-DD transceiver is widely used in 400G telecommunications connections, data center interconnects (DCI), metropolitan area networks, long-haul transmission, and high-performance computing network applications. The 400G QSFP-DD LR8 optical module is ideal for data center applications such as Ethernet switching and routing, storage area networks, and high-performance computing. It is also suitable for other areas such as 5G mobile networks, high-speed video streaming, artificial intelligence, and cloud computing.
