## Summary description

The BlueOptics SFP-BXU34-20KM-CN-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing and weighs 20 g. The module has a mean time between failures (MTBF) of 1,000,000 hours, ensuring reliability for network applications.

## Long description

The BlueOptics SFP-BXU34-20KM-CN-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. Housed in a metal enclosure with a silver finish and weighing approximately 20 g, the module offers a compact, MSA-compliant SFP form factor suitable for use in switches, routers and other network devices that accept standard SFP transceivers. The transceiver supports single-fiber bidirectional transmission using LC Simplex connectors with separate transmit and receive wavelengths and includes digital diagnostic monitoring for real-time parameter access where supported by the host hardware.
Advantages
The module provides full MSA compatibility and is manufactured to industry standards to ensure interoperability with a wide range of network equipment. With a rated MTBF of 1,000,000 hours, the BlueOptics transceiver delivers long operational life and reduced maintenance requirements. The metal housing offers mechanical robustness and thermal stability, while the single-mode LC Simplex interface enables point-to-point fiber links up to 20 km at gigabit speeds.
Suitable for
1 Gbps single-mode fiber links up to 20 km
Switch-to-switch and router uplinks using LC Simplex connectors
Long-distance enterprise and carrier access links
Environments requiring DDM/DOM monitoring for diagnostics
Key specifications
Interface type: SFP (MSA compliant)
Data rate: up to 1250 Mbit/s (1000BASE-BX-U)
Fiber type: Single-mode fiber
Connector: LC Simplex (single-fiber bidirectional)
Wavelengths: separate transmit and receive wavelengths for BX-U operation (TX/RX pair)
Maximum link distance: up to 20 km
Housing: metal, silver colour
Weight: approx. 0.02 kg
Digital diagnostics: DDM/DOM support (when supported by host)
MTBF: 1,000,000 hours
How to use
Insert the SFP transceiver module into a compatible SFP slot on the network device until it clicks into place, then secure the module according to the device manufacturer’s instructions. Connect an LC Simplex single-mode patch cord to the module’s LC port and route the fibre to the corresponding transceiver on the remote device. If the host hardware supports digital diagnostics, enable or query the DDM/DOM functions through the device management interface to monitor supply voltage, optical power, laser bias and temperature. Power on the devices and verify link status and negotiated speed in the network equipment’s interface.
Usage recommendations
Use certified single-mode LC Simplex patch cords and maintain proper fibre handling practices (clean connectors, avoid sharp bends and protect connectors from contamination) to achieve reliable performance over the specified 20 km range. Confirm host compatibility and DDM support in the target device before deployment.
