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

QSFP-DD 400G ZR and ZR+/ZR+ Pro coherent optical modules have obvious differences in transmission distance, module specifications, power consumption, modulation format and application scenarios, etc. QSFP-DD 400G ZR+ has longer transmission distance, more advanced modulation and coding technology, and stronger digital signal processing capability, and supports coverage/capacity optimisation over a variety of fibre links. optimised for ultra-long-haul data centre interconnections. The QSFP-DD 400G ZR+ Pro is a high Tx power version that increases Tx optical power up to +1dBm for longer reach in P2P applications over dark fibre.

What types of networks can it be used in?

Both QSFP-DD 400G ZR and ZR+/ZR+ Pro optical modules can be used in a variety of network topologies, including point-to-point, star, and ring networks.

Description

Cisco DP04QSDD-HE0 Compatible 100-400GbE High-Power (Bright) DCO QSFP-DD DWDM Tunable Coherent ＞120km DDM/DOM Duplex LC SMF Optical Transceiver Module (SMF, Coherent, LC, DOM, Open ZR+ Pro)

NADDOD QDD-400G-ZR+ Pro is a C-Band optical frequency tunable coherent optical module, combines 7nm coherent DSP ASIC functionality with best in class ultra-narrow line-width tunable lasers, high speed modulators and high responsively coherent receivers to deliver high performance at 100G DP-QPSK / 200G DP-QPSK / 300G DP-8QAM / 400G DP-16QAM modulation format. With EDFA and VOA inside the TX optical path the output optical power is -10~1dBm tunable, at the 400G Gray Light mode (193.7THz) the output power is 4dBm. The 400G QSFP-DD ZR+ Pro is designed to 100G/200G long haul and 300G/400G Metro IP over DWDM applications without inline chromatic dispersion compensation.
