Quad small form pluggable double density (QSFP-DD) transceivers maximize port economy and density by utilizing multiple lanes of data.
The QDD-400G-LR4-S is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP56-DD) optical module designed for 10km optical communication applications.
Compatibility Validated in Arista/NVIDIA/Cisco RoCE Networking.
The QDD-400G-LR4-S 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.
This QDD-400G-LR4-S fiber optic module is easy to install, hot swappable transceiver has been programmed, uniquely serialized and data-traffic and application tested to ensure that it will initialize and perform identically.
