Description
The AddOn Cisco® QDD-400G-ZRP-S Compatible TAA 400GBase-ZR+ QSFP-DD Transceiver delivers high-capacity, long-reach optical connectivity for next-generation data centers, metro networks, and enterprise backbones. Designed for seamless compatibility with Cisco® hardware, this coherent optical transceiver supports up to 400Gbps throughput over single-mode fiber (SMF) using a tunable C-band transmitter across 1528.77 nm – 1567.13 nm wavelengths.
Engineered for OpenZR+ applications, it supports flexible payloads (400G/300G/200G/100G) and offers advanced Digital Optical Monitoring (DOM) for real-time diagnostics. With a hot-pluggable QSFP-DD (Type 2A) form factor, duplex LC connector, and forward error correction (O-FEC) with 11.6 dB net coding gain, it ensures reliable long-haul performance and superior optical signal quality.
Each unit is uniquely serialized, thoroughly tested for data traffic and application performance, and fully compliant with Trade Agreements Act (TAA) requirements. Backed by AddOn’s limited lifetime warranty, this transceiver is the ideal choice for future-ready, high-bandwidth optical deployments.
