SFP28 transceiver module BlueOptics 407-BBYK-BO 25000 Mbit/s 850 nm

The BlueOptics 407-BBYK-BO is an SFP28 transceiver module designed for 25G optical links. It supports a maximum data transfer rate of 25,000 Mbit/s over multimode fiber at an operating wavelength of 850 nm and uses an LC (UPC) duplex connector in a compact SFP28 form factor. The module is compatible with Dell hardware platforms that support the equivalent 25GBASE-ESR SFP28 and is intended for short-reach links up to 300 m. With a lightweight metal housing in silver and a compact design, it is suitable for dense networking environments where space and port density matter.

Advantages

The module provides 25G performance for Ethernet and other high-speed protocols while maintaining an industry-standard SFP28 footprint for interoperability. Compliance with MSA electrical and mechanical specifications ensures plug-and-play operation in compatible switches, routers and storage systems. The LC duplex multimode interface and 850 nm optics make it suitable for short-reach campus and data center connections. Its light weight and compact size simplify handling and installation in high-density racks.

How to use

Install the transceiver into an SFP28-compatible port of a switch, router or storage device following the host hardware manufacturer’s instructions. Connect LC duplex multimode fiber patch cords to the module’s LC (UPC) connectors, ensuring correct transmitter-to-receiver polarity. Verify that the host device supports the SFP28 module and configure the interface as required by your network operating system. Monitor link status and diagnostics via the host device to confirm proper operation.

Recommendations

Use high-quality multimode fiber patch cords and maintain correct polarity for optimal performance. Confirm that the target device supports 25G SFP28 optics and, if available, enable digital diagnostics (DDM/DOM) on the host to monitor supply voltage, optical power and temperature. For best results in data center environments, route fibers with minimal bends and follow industry installation practices to preserve link budget and reliability.
