Description
The Cisco QDD-400G-ZRP-S is a high-performance 400G optical transceiver module designed for data center and enterprise network environments requiring long-reach connectivity. Built in the QSFP-DD form factor, this module supports dual-rate operation at 400G and 4x100G, offering flexibility for evolving network architectures. It utilizes advanced DWDM (Dense Wavelength Division Multiplexing) technology and supports ZR+ optics, enabling transmission distances up to 120 km over single-mode fiber with FEC (Forward Error Correction). The module is hot-swappable and designed for high-density applications, making it ideal for scaling bandwidth without extensive infrastructure upgrades.
Key features include support for coherent detection, a built-in digital diagnostics monitoring interface, and compatibility with OIF 400ZR/400ZR+ standards. The transceiver integrates advanced DSP (Digital Signal Processing) and tunable lasers, supporting C-band wavelength tuning for optimized performance across DWDM systems. It operates with a typical power consumption of 16W and is compliant with the QSFP-DD MSA, allowing interoperability across a wide range of Cisco platforms. This unit is a cost-effective solution for buyers seeking used or refurbished hardware to expand their network capacity with reliable, long-haul 400G connectivity.
