D-Link DEM-QX10Q-LR4 40GBASE-LR4 QSFP+Transceiver 10 km
The D-Link QSFP Multi Transceiver is a high-performance 40GBASE-LR4 QSFP+ optical transceiver designed for long-distance, high-bandwidth connections across enterprise and data center networks. Operating over single-mode fiber (SMF), it supports data transmission up to 10 kilometers, providing a robust solution for core and aggregation layer deployments requiring exceptional throughput and reliability.
Utilizing four independent transmit and receive channels, each operating at 10.3125 Gbps, the module achieves a combined data rate of 40 Gbps full-duplex, enabling seamless backbone scalability. Built to comply with IEEE 802.3ba 40GBASE-LR4 standards and MSA (Multi-Source Agreement), the DEM-QX10Q-LR4 ensures multi-vendor interoperability, superior optical performance, and consistent quality. It also features Digital Diagnostics Monitoring (DDM) for real-time analysis of optical parameters—ensuring early detection of potential link issues.
