Description
The AddOn Cisco® QDD-400G-PLR4-S compatible QSFP-DD transceiver provides reliable 400GBase-PLR4 throughput over single-mode fiber (SMF) for distances up to 10km using a wavelength of 1310nm via an MPO connector. This high-performance optical module is engineered to be 100% compatible with the equivalent Cisco® transceiver and is fully compliant with INF-8628 standards.
Designed for data center, enterprise, and high-performance networking environments, the transceiver is hot-pluggable and TAA (Trade Agreements Act) compliant, supporting secure government and enterprise deployments. It features Digital Optical Monitoring (DOM) for real-time diagnostics, CMIS 4.0 management interface, and robust ESD and EMI protection for enhanced reliability.
Each unit is programmed, uniquely serialized, and rigorously tested for data traffic and application performance, ensuring seamless integration and identical operation as the OEM part. With RoHS compliance, lead-free design, and AddOn’s limited lifetime warranty, this transceiver offers outstanding reliability and value for 400G Ethernet applications.
