Description
QSFP-DD-400G-LR8 Module is 400GBASE-LR8 QSFP-DD PAM4 1310nm 10km DOM Duplex LC SMF Optical Transceiver Module
QSFP-DD-400G-LR8 Module Product Overview
The module is designed to support 400G Ethernet, which is suitable for data center links up to 10km over single mode fiber with FEC. 400G QSFP-DD LR8 module is compatible with IEEE 802.3bs 400GBASE-LR8. Additionally, the module supports eight electrical interface lanes which operate in 50G PAM4 encoding mode resulting in 400G (8x50G) data rate.
QSFP-DD (Quad Small Form Factor Pluggable Interface Double Density) is the latest module form factor for 400G data rates. The design provides an eight-channel electrical interface compared to traditional single- or quad-channel interfaces, increasing bandwidth, channel capacity, and port density. Defined by the QSFP-DD MSA group, this module addresses the need for high-density, high-speed networking solutions in a backward-compatible form.
