QDD-400G-FR4-S Overview
The Cisco QDD-400G-FR4-S module is a 400G QSFP-DD transceiver designed for data center interconnects over single mode fiber. Utilizing advanced PAM4 modulation and 4 wavelengths multiplexed together, this module supports 400GbE links up to 2km over SMF.
A duplex LC connector handles the single pair of fibers carrying the 4 multiplexed wavelengths internal to the module. Support for 400GbE connectivity allows an easy upgrade path from 100GbE switches using QSFP28 modules to 400G platforms.
Overall, the Cisco QDD-400G-FR4-S provides 400GbE connectivity up to 2km over SMF in a pluggable QSFP-DD form factor, enabling high density 400G links between data center switches.
Key Features
- 400GBASE-FR4 compliant
