Arista Networks QDD-400G-LR4 Compatible 400GBASE-LR4 QSFP-DD PAM4 1310nm 10km DOM Duplex LC SMF Optical Transceiver Module
Arista Networks QDD-400G-LR4 Compatible 400G-LR4 QSFP-DD PAM4 Optical Transceiver Module (SMF, 1310nm, 10km, LC, DOM)
The 400GBASE-LR4 module, Duplex LC connector, up to 10km over parallel single-mode fiber. It is compliant to IEEE 802.3bs protocol and 400GAUI-8/CEI-56G-VSR-PAM4 standard.
The 400 Gigabit Ethernet signal is carried over four CWDM grid optical wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.
