Dell 25GbE SFP28 SR Short-Reach 850nm Multi-Mode Optical Transceiver (407-BCHI)

The Dell 25GbE SFP28 Short-Reach (SR) Optical Transceiver Module (Dell Part Numbers: PY7V9 / 0PY7V9 / Dell Ordering SKU: 407-BCHI) is an enterprise-grade small form-factor pluggable optical transceiver designed to deliver high-speed 25 Gigabit Ethernet connectivity across short-distance fiber networks. Operating at an 850nm VCSEL wavelength over multi-mode fiber (MMF), this hot-pluggable module enables reliable, low-latency data transmission between Dell PowerEdge servers, storage arrays, and core data center switches.

Compliant with SFP28 MSA standards and IEEE 802.3by 25GBASE-SR specifications, this transceiver supports link distances of up to 70 meters on OM3 multi-mode fiber and up to 100 meters on OM4 multi-mode fiber using LC duplex connectors. Built with digital optical monitoring (DOM) capabilities, it allows IT administrators to perform real-time diagnostic monitoring of operating parameters—including optical transmit/receive power, module temperature, supply voltage, and laser bias current—directly through Dell iDRAC or network switch management interfaces.

Available from DataDive, your trusted Server Parts Distributor in Qatar, this authentic Dell 25GbE optical transceiver is available in our Networking collection, ideal for upgrading server uplink connections, deploying high-density spine-leaf switch topologies, supporting virtualized network clusters, and replacing failed optical modules across Dell PowerEdge servers and PowerSwitch networking hardware.
