Description
The AddOn QDD-400G-DCO-ZRP-AO is a high-performance, MSA-compliant 400GBase-ZR+ QSFP-DD coherent optical transceiver designed for long-reach, high-capacity data center interconnects and service provider networks. Supporting 400 Gbps, 300 Gbps, 200 Gbps, and 100 Gbps payloads over single-mode fiber (SMF), it delivers unmatched flexibility and performance for metro and long-haul applications.
Featuring a tunable C-band transmitter and coherent receiver technology, this transceiver operates across the 1528.58 nm to 1567.34 nm wavelength range and supports Open ZR+ deployments with digital optical monitoring (DOM) for real-time diagnostics. It is fully hot-pluggable with a QSFP-DD (Type 2A) footprint and supports Duplex LC connectivity.
With O-FEC (15%) forward error correction, up to 11.6 dB net coding gain, and advanced signal integrity features such as PAM4 electrical interfaces, high OSNR tolerance, and chromatic dispersion compensation, the QDD-400G-DCO-ZRP-AO is ideal for carrier-class, enterprise, and hyperscale environments demanding long-reach coherent optics and seamless integration.
