Cisco QDD-400G-LR8-S 400GB BASE-LR8 10km Duplex SMF QSFP-DD Transceiver

Cisco QDD-400G-LR8-S is a QSFP-DD transceiver module manufactured by Cisco. It supports 400 Gbps Ethernet transmission over single-mode fiber (SMF) using LC connectors and operates within a wavelength range of 1270 nm to 1330 nm.

The module enables up to ten kilometers of optical reach on duplex SMF, making it suitable for long-haul point-to-point links in data centers or telecom networks with existing LC infrastructure. Designed for QSFP-DD ports, the unit integrates eight channels through LAN-WDM multiplexing. Power type is standard pluggable; cooling depends on system airflow compatibility per chassis specifications.
