The module is designed for ZR 400G DCI / PTN applications and ZR+200G metro long-haul OTN applications. It provides high-speed data channels, IIC interface module control and state alarm reporting with 3. The wide variety of modules gives you flexible and cost-effective options for all types of interfaces. Cisco offers a range of GBIC, SFP, XFP, SFP+, CXP, CFP, Cisco CPAK, and QSFP+ pluggable. This guide explores the evolving landscape of 400G coherent optics, comparing ZR standards, vendor-specific and performance-optimized modules, while also offering some insight into their deployment, considerations, power consumption, and interoperability. The 400ZR is an Optical Interworking Forum (OIF) standard for transporting 400GbE over long distances through fiber optic cables. With one VOA inside the TX optical path the out output optical power has 4dB attenuation window.
