## Summary description

The BlueOptics SFP-BXU34-20KM-MR-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing, weighs 20 g, and has an MTBF of 1,000,000 hours, making it a reliable choice for network applications.

## Long description

The BlueOptics SFP-BXU34-20KM-MR-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. The module uses an LC simplex connector and supports long-distance links up to 20 km using a wavelength pair for bi-directional transmission (transmit and receive on different wavelengths). Housed in a metal enclosure with a compact SFP form factor and a weight of approximately 20 g, this transceiver provides industry-standard electrical and mechanical compatibility for SFP ports.
Advantages
This BlueOptics SFP transceiver offers MSA-compliant interoperability with a wide range of network devices that accept SFP 1000BASE-BX-U modules. The module’s metal housing contributes to thermal stability and robustness in rack-mounted network equipment. With an MTBF of around 1,000,000 hours and support for single-mode fiber over distances up to 20 km, it is suitable for deployments that require stable long-reach Ethernet or similar optical links. The transceiver also supports Digital Diagnostics Monitoring (DDM/DOM) when the host device implements that feature.
Suitable for
Long-reach Gigabit Ethernet links up to 20 km
Interconnection of switches, routers and access equipment with SFP ports
Fiber-to-fiber links using LC simplex single-mode fiber
Environments where MSA-compliant, replaceable optics are required
Key specifications
Interface type: SFP (pluggable transceiver)
Protocol: 1000BASE-BX-U (Gigabit Ethernet over single-mode fiber)
Maximum data transfer rate: 1250 Mbit/s
Wavelengths: Bi-directional pair (separate transmit and receive wavelengths for BX-U operation)
Connector type: LC simplex
Fiber type: Single-mode fiber (SMF)
Maximum link distance: up to 20 km (depending on fiber and link budget)
Housing: metal SFP form factor
Product colour: silver
Weight: approx. 0.02 kg
Mean time between failures (MTBF): approx. 1,000,000 hours
Digital diagnostics monitoring: supported when enabled by host hardware (DDM/DOM compliant)
How to use
Install the SFP module into an empty SFP slot of a compatible switch, router or other network device while the host port is powered down or according to the device manufacturer’s hot-plug instructions. Connect a single-mode LC simplex fiber patch cable between this transceiver and the remote transceiver; ensure correct orientation because BX-U modules use different wavelengths for transmit and receive. Verify that the host device recognizes the module and that link status and intended data rate are established. If available, enable DDM/DOM on the host to monitor supply voltage, laser bias current, optical output power, received power and module temperature.
Usage recommendations
Use quality single-mode fiber and LC simplex patch cords, maintain clean connector endfaces, and match the correct transmit/receive orientation for BX-U links. Confirm that the network device firmware supports third-party SFP modules and, if needed, enable DDM/DOM monitoring to assist with diagnostics. For reliable long-distance links, verify link budget calculations and avoid excessive connector or splice losses.
