The 400GBASE-LR8 module supports link lengths of up to 10km over a standard pair of G.652 single mode fiber (SMF) with duplex LC connectors. It is compliant to IEEE 802.3bs protocol and 400GAUI-8/CEI-56G-VSR-PAM4 standard. The 400 Gigabit Ethernet signal is carried over eight wavelengths. Multiplexing and demultiplexing of the eight wavelengths are managed within the device.
Note: The FS P/N is changed from QSFPDD-LR8-400G to QDD-LR8-400G, but the product is the same. Only the FS P/N has been changed.
