The Dell QSFP-40G-SR4-ON is a hot-pluggable QSFP+ optical transceiver (Manufacturer Part Number QSFP-40G-SR4-ON / V3XJK) that provides 40 Gbps Ethernet over multimode fiber for short-range data-center interconnects. It uses 850 nm wavelength with 40GBASE-SR4 signaling and employs an MPO/MTP multi-fiber connector, supporting up to 100 meters on OM3 MMF or up to 150 meters on OM4 MMF. Compatible with Dell networking switches and other platforms, this module is commonly deployed in data centers for spine-leaf interconnects, switch-to-switch links, and high-performance computing networks, enabling fast data transfer with low latency between servers, storage, and switches.
