What is the difference between QSFP-DD 400G ZR and ZR+?

QSFP-DD 400G ZR and ZR+ coherent optical modules have obvious differences in transmission distance, module specifications, power consumption, modulation format and application scenarios, etc. QSFP-DD 400G ZR+ has a longer transmission distance, more advanced modulation and coding technology and stronger digital signal processing capability, which provides a longer transmission capability and is suitable for ultra-long-distance data center interconnection.

What kind of networks can it be used in?

QSFP-DD 400G ZR and ZR+ optical modules can be used in a variety of network topologies, including Point to Point, Star and Ring networks.
