QSFP-DD 400G-ZR+ High TX Power DCO Pluggable - C-Band

Cisco is now expanding the range of 400G Digital Coherent QSFP-DD transceivers, introducing High Tx Power variants (+1dBm of Tx Power). Thanks to the miniaturization of the technology with a 7-nm manufacturing procedure and innovation in silicon photonic technology, it is now possible to also squeeze an Optical Amplifier (Mini-EDFA) within a QSFP-DD form factor.

Cisco 400G QSFP-DD High-Power (Bright) Optical module’s small size and low power make it an optimal choice for a wide range of DCI/Cloud, metro access/aggregation, wireless backhaul, and campus interconnect applications.

Cisco 400G QSFP-DD High-Power (Bright) Optical module is mechanically compliant to the QSFP-DD Type 2A Module Specification. The QSFP-DD module contains a PCB with a 76-contact card-edge electrical interface to external host-side logic. The media interface is a duplex LC connector coupled to a 1550-nm optical fiber carrying the DP-mQAM coherent signal. The signaling operates in the C-band.
