The 400GBASE-ER8 module, Duplex LC connector, up to 40km over parallel single-mode fiber. It is compliant to IEEE 802.3cn protocol and 400GAUI-8, QSFP-DD HW Rev 5.0 and QSFP-DD CMIS Rev 4.0 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-ER8-400G to QDD-ER8-400G, but the product is the same. Only the FS P/N has been changed.
