The 400G QSFP-DD 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. The 400G QSFP-DD 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. Cisco offers a range of GBIC, SFP, XFP, SFP+, CXP, CFP, Cisco CPAK, and QSFP+ pluggable modules. Reconfigurable optical add/drop multiplexers (ROADMs) in existing and emerging DWDM transport networks require a high optical launch power (0 dBm) and high transmit in-band and out-of-band optical. It is compliant with QSFP-DD MSA, IEEE 802. 3bs protocol and 400GAUI-8 standards. It can be used in data centers, high-performance computing networks, enterprise core and distribution layers, and service provider applications. Power Consumption, Support 4x 100G,QSFP-DD Port.
