Detailed Specifications
HPE Q7F11A 40GBASE-SR4 QSFP+ Optical Transceiver
Overview
The HPE Q7F11A is a QSFP+ transceiver module designed for 40 Gigabit Ethernet over multimode fiber. It uses 850 nm optics and supports link distances up to ~100 m on OM3 fiber and more on OM4, enabling high-density, high-throughput connections in data-center and HPC environments. The module is hot-pluggable, supports digital diagnostics monitoring (DDM), and is compatible with HPE M-Series switches and other standard QSFP+ ports.
Key Features
40 Gb/s aggregated throughput via SR4 optics
850 nm wavelength VCSEL for multimode fiber (MMF)
MPO/MTP-12 connector for high-density fiber cabling
Hot-plug QSFP+ form factor
Digital diagnostics (DDM) for real-time monitoring
