Description
The Juniper QFX-QSFP-40G-SR is a high-performance 40 Gigabit Ethernet transceiver module designed for short-range data center applications. Housed in a compact QSFP+ form factor, this module supports multimode fiber (MMF) connections and is optimized for distances up to 100 meters over OM3 fiber or up to 150 meters on OM4. It operates over four independent full-duplex channels, each capable of 10 Gbps, aggregating to a total data rate of 40 Gbps. Designed for high-density environments, it provides a cost-effective solution for scaling bandwidth within spine-leaf architectures or top-of-rack deployments.
This transceiver features an MPO/MTP connector interface and complies with IEEE 802.3ba 40GBASE-SR4 standards, ensuring broad compatibility with a range of Juniper QFX Series switches and other industry-standard equipment. It supports Digital Optical Monitoring (DOM) for real-time diagnostics, including temperature, voltage, and optical power levels. When purchasing used, buyers should ensure the module has been tested for signal integrity and DOM functionality to guarantee reliable performance. The robust design and proven reliability of the QFX-QSFP-40G-SR make it a solid choice for expanding or upgrading existing 40GbE infrastructure.
