Product Overview
QDD-LR4-400G optical module (single mode, 1310nm, 10km, LC, DOM)
The QDD-LR4-400G optical module, featuring a duplex LC connector, can achieve a transmission distance of up to 10km over parallel single-mode fiber. This optical module complies with the IEEE 802.3bs protocol and the 400GAUI-8/CEI-56G-VSR-PAM4 standard.
The 400G Ethernet signal is transmitted through four CWDM optical wavelengths. The multiplexing and demultiplexing of the four wavelengths are managed internally within the device.
