Cisco Compatible 400GBASE-ER8 QSFP-DD PAM4 1310nm 40km Duplex LC SMF DOM Optical Transceiver Module
The 400GBASE-ER8 module supports link lengths of up to 40km over a standard pair of G.652 single mode fiber (單模量單位（ SMF) with duplex LC connectors. 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.
