SFP transceiver module BlueOptics SFP-BXU34-20KM-PT-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-20KM-PT-BO is a single-mode fiber SFP transceiver module designed for bi-directional 1000BASE-BX-U links with a maximum data transfer rate of 1250 Mbit/s. Housed in a durable metal casing and weighing 20 g, this module provides long-distance optical transmission up to 20 km using LC simplex connection. The module supports digital diagnostics (DDM/DOM) for real-time monitoring of operating parameters and is built to MSA mechanical and electrical standards for interoperability with compatible network hardware.

Advantages

The transceiver offers a compact SFP form factor and a metal housing that provides mechanical stability and thermal dissipation. With an MTBF rating of approximately 1,000,000 hours, it is intended for reliable continuous operation. Support for DDM/DOM enables remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature to simplify maintenance. Compliance with SFP MSA standards ensures plug-and-play compatibility with equipment that accepts MSA-compliant SFP modules.

How to use

Insert the SFP transceiver into an SFP-compliant port of a switch, router or media converter while the host device is powered according to the device vendor's instructions. Connect a single-mode LC simplex patch cable between this module and the remote transceiver, observing correct fiber polarity for BX bi-directional links. Verify link status in the host device and, if available, read DDM/DOM values to confirm operating conditions. Follow proper ESD precautions when handling the module and protect the optical interface with dust caps when not in use.

Recommendations

Use certified single-mode fiber and high-quality LC patch cords to achieve rated distances. Confirm that the host hardware supports 1000BASE-BX-U modules and DDM/DOM functionality if diagnostics are required. Keep firmware and device driver versions up to date to avoid interoperability issues.
