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

The BlueOptics SFP-BXU34-20KM-CO-BO is a single-mode SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a durable metal casing and complying with MSA form-factor requirements, this module supports simplex LC connections and delivers reliable optical links over distances up to 20 km. It is intended as a compatible alternative for systems that accept 1000BASE-BX-U SFP modules and offers Digital Diagnostics Monitoring (DDM) when supported by host hardware.

Advantages

The module provides a compact SFP interface with a 1250 Mbit/s throughput suitable for Gigabit Ethernet and similar protocols. The metal housing improves mechanical durability and thermal dissipation. Built and tested to MSA-compatible standards, the transceiver supports digital diagnostics for real-time monitoring of link parameters when the host device implements DDM/DOM. The design targets long operational lifetime and high availability for network environments.

Key specifications

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or other networking device while the device is powered down or following the vendor’s hot-swap guidelines. Connect a single-mode LC simplex fiber patch cord matched for BX-U bi-directional operation to the LC port. Ensure the remote module uses the complementary transmit/receive wavelengths for BX-U operation and confirm link settings (speed/duplex) on both endpoints. If DDM is required, verify that the host platform supports digital diagnostics to read voltage, temperature, transmit/receive power and laser bias current.

Recommendations

Use factory-tested single-mode fiber patch cords and verify polarity for BX-U bi-directional links. When deploying in racks or high-density systems, allow adequate cooling and adhere to the host vendor’s compatibility list. Test the transceiver in your target hardware before large-scale rollout to ensure full functionality and DDM reporting if required.
