Description
The AddOn QDD-400GB-PLR4-AO is a high-performance QSFP-DD optical transceiver designed for 400GBase-PLR4 applications. It delivers up to 10km of data transmission over single-mode fiber (SMF) using a 1310nm wavelength via an MPO connector. Built to MSA standards, it supports Digital Optical Monitoring (DOM) and CMIS 4.0, ensuring reliable performance and easy network integration.
With excellent ESD protection, low EMI metal housing, and full hot-pluggability, this transceiver is ideal for demanding 400G Ethernet deployments. It is RoHS compliant, lead-free, and TAA-compliant, making it suitable for government and enterprise use. Each unit is uniquely serialized and rigorously tested for seamless interoperability, backed by AddOn’s limited lifetime warranty.
