QDD-2X100-LR4-S Overview
The Cisco QDD-2X100-LR4-S module is a 2x100G QSFP-DD transceiver designed for long reach data center interconnects over single mode fiber. With support for two 100GBASE-LR4 optical interfaces, this module enables breakout from 400G switch ports to provide high density 100GbE connectivity.
A dual duplex CS connector handles two pairs of fibers, one for each internal 100G transceiver. This module helps enable a migration to higher speed 400G platforms while maintaining support for existing 100GbE cabling and infrastructure across longer distances.
Overall, the QDD-2X100-LR4-S module provides two 100GbE interfaces over SMF to provide 200GbE aggregate bandwidth, doubling port capacity compared to QSFP28 designs.
