Description

D-Link DEM-QX01Q-SR4 40GBASE-SR4 QSFP Multi Transceiver

The D-Link DEM-QX01Q-SR4 is a high-performance 40GBASE-SR4 QSFP+ optical transceiver designed for ultra-fast data center, enterprise, and carrier-grade network applications. Utilizing Quad Small Form-factor Pluggable Plus (QSFP+) technology, this transceiver supports four transmit and four receive channels, each operating at up to 10.5 Gb/s, enabling a total aggregated bandwidth of 40 Gbps over multi-mode fiber (MMF).

Engineered for high-density switching environments, the DEM-QX01Q-SR4 provides exceptional reliability and scalability for short-range interconnects between switches, routers, and servers. It operates on an 850 nm wavelength and supports transmission distances up to 100 meters on OM3 and 150 meters on OM4 multimode fiber, making it ideal for top-of-rack (ToR), middle-of-row (MoR), and spine-leaf data center architectures.

Key Features
