The LINK-PP Cisco QDD-400G-ZRP-S Compatible QSFP-DD 400GBase-ZR+ Transceiver Module is an enterprise-grade, pluggable Digital Coherent Optics (DCO) solution engineered for next-generation 400Gbps metro-regional networks and long-haul Data Center Interconnects (DCI).Designed to overcome the distance limitations of standard 400ZR modules, this advanced ZR+ (ZR-Plus) transceiver supports an extended transmission range of over 600km over standard Duplex LC/UPC Single-Mode Fiber (SMF). It features a high-performance C-band tunable transmitter operating across the 1528.77nm to 1566.52nm wavelength range, fully compliant with the ITU-T 50GHz grid (Channels CH13 to CH61). Equipped with an onboard Digital Signal Processing (DSP) engine, the module manages complex modulation formats and chromatic dispersion compensation directly on the chip. It also features integrated Digital Optical Monitoring (DOM) for real-time diagnostics of optical power, temperature, and supply voltage.As a 100% hot-pluggable drop-in replacement for the Cisco QDD-400G-ZRP-S, this module delivers full software and hardware interoperability with Cisco routing platforms. It complies strictly with QSFP-DD MSA, OpenZR+, and CMIS standards, offering network architects a scalable, ultra-long-distance DWDM solution with maximum spectral efficiency and reduced total cost of ownership.
