QDD-800G-2LR4 Compatible 800GBASE 2x LR4 QSFP-DD PAM4 Optical Transceiver Module, SMF, 1310nm, 10km, Dual Duplex LC/UPC, DOM.

The 800GBASE 2x LR4 QSFP-DD Optical Transceiver Module is designed to support 800GBASE Ethernet over distances up to 10 km using eight pairs of single-mode fiber (SMF) with dual duplex LC/UPC connectors. It complies with IEEE 802.3cu and CMIS Rev. 5.0 standards.

This module features two duplex LC connectors, allowing for two independent 400G LR4 links from a single 800G transceiver—eliminating the need for optical breakout cables. It can also be configured as a single 400G port (4×100G PAM4) for 400G Ethernet applications. It is well-suited for 800G and 400G Ethernet networks, data centers, and 2×400G LR4 breakout deploymentSpecifications
