SFP transceiver module BlueOptics SFP-BXU35-20KM-DE-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-20KM-DE-BO is an SFP fiber optic transceiver module designed for single-mode links with a maximum data rate of 1250 Mbit/s. Housed in a metal casing and weighing approximately 20 g, this module supports LC simplex connections and is built to operate reliably over distances up to 20 km. The module implements a bi-directional 1000BASE-BX-U configuration with separate transmit and receive wavelengths for single-fiber transmission and supports Digital Diagnostics Monitoring (DDM/DOM) when the host hardware provides the interface.

Advantages

The module’s metal housing provides mechanical durability and thermal stability while the compact SFP form factor enables hot-pluggable installation in compatible network devices. With an MTBF of around 1,000,000 hours and support for standard MSA SFP electrical and mechanical interfaces, the transceiver is suitable for long-distance Ethernet, Fibre Channel over Ethernet and synchronous transport applications up to 1.25 Gbit/s. Built to industry standards, it offers interoperability with devices that accept 1000BASE-BX-U SFP modules and includes DDM support for remote diagnostics where supported by the host.

How to use

Insert the BlueOptics SFP-BXU35-20KM-DE-BO into an available SFP cage on a compatible switch, router or storage device while the device is powered according to the vendor guidelines for hot-pluggable modules. Connect an appropriate single-mode LC simplex patch cable and ensure the remote end uses a matching BX-U transceiver with complementary wavelengths. Verify link status in the host device and, if available, enable and read Digital Diagnostics Monitoring (DDM/DOM) information through the device management interface for supply voltage, laser bias, output power, received power and temperature.

Recommendations

Use high-quality single-mode LC simplex patch cords and follow manufacturer guidelines for insertion, removal and electrostatic precautions. Confirm host device firmware or driver compatibility for third-party transceivers and enable DDM only if supported by your hardware to access diagnostic data.
