D-Link DEM-QX10Q-LR4 40GBASE-LR Single-Mode QSFP+ Optical Transceiver

Accelerate core networking and surveillance backbones with the D-Link DEM-QX10Q-LR4 40GBASE-LR QSFP+ optical transceiver. This D-Link QSFP+ module delivers a single‑mode, LR4 40 Gigabit Ethernet connection that simplifies aggregation and long‑reach transport for data centers, enterprise wiring closets and security/surveillance monitoring systems. The hot‑pluggable QSFP+ form factor lets technicians swap or upgrade modules without disrupting operations, reducing downtime and service windows. Integrated Digital Diagnostics Monitoring (DDM) provides live insight into transmit/receive power, temperature and voltage so teams can detect and resolve fiber issues before they impact critical applications. Designed for optical fiber environments, the DEM-QX10Q-LR4 supports high-density deployments and wavelength multiplexing to lower fiber counts and improve link reliability for video surveillance backhaul, access control, and centralized logging/monitoring. Choose this D-Link 40G transceiver to future‑proof your network transport layer and simplify maintenance—ideal for networking and security teams looking to boost capacity and visibility.
