The Cisco QDD-2X100-LR4-S-RF is a remanufactured (Cisco Refresh) QSFP-DD transceiver module that provides two independent 100GBASE-LR4 interfaces in a single high-density form factor. It is designed to deliver 200Gbps of aggregate throughput over 10km of single-mode fiber (SMF). Each 100G channel operates over four wavelengths in the 1310nm range and is terminated with a dual duplex CS connector. This module is ideal for high-density data center deployments, enabling breakout capability from 400G ports or supporting high-capacity enterprise core and distribution links. As a Cisco Refresh product, it undergoes a rigorous remanufacturing process to meet original factory specifications for performance and reliability.
