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.
Versions configured for 400G ZR/ZR+ applications spanning distances from 80 km up to 120+ km.
