## Summary description

The BlueOptics SFP-BXU34-20KM-QL-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a durable metal housing and an MTBF of 1,000,000 hours, making it reliable for network applications. Weighing only 20 g, it is lightweight and easy to install.

## Long description

The BlueOptics SFP-BXU34-20KM-QL-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U links with a maximum data transfer rate of 1250 Mbit/s. Housed in a durable metal enclosure and weighing approximately 20 g, the module follows MSA SFP form-factor conventions and is intended for installation in compatible SFP ports to enable optical connections up to 20 km when used with appropriate single-mode fiber and LC simplex connectors.
Advantages
This BlueOptics SFP transceiver offers a compact, metal-bodied design that supports a 1250 Mbit/s data rate and low weight for easy handling and installation. The module has a long mean time between failures (MTBF) of 1,000,000 hours, indicating suitability for continuous operation in network environments. Compliance with SFP mechanical and electrical standards ensures interoperability with devices that accept standard SFP modules.
Suitable for
Single-mode optical links in enterprise and service-provider networks
Fiber connections between switches, routers and storage systems supporting SFP
Point-to-point links up to 20 km using LC simplex connectors
Key specifications
Interface type: SFP form factor
Maximum data transfer rate: 1250 Mbit/s
Fiber type: single-mode (designed for single-fiber BX operation)
Wavelengths: separate transmit and receive wavelengths for bidirectional operation over one fiber
Connector type: LC simplex
Maximum transmission distance: up to 20 km (dependent on fiber and link conditions)
Housing: metal
Weight: approx. 0.02 kg
Digital diagnostics: supported where host hardware implements DDM/DOM (subject to host support)
How to use
Install the BlueOptics SFP-BXU34-20KM-QL-BO into an SFP slot on compatible networking equipment according to the device manufacturer’s instructions. Use an LC simplex fiber patch cord and ensure correct orientation for single-fiber bidirectional links (transmit and receive are on separate wavelengths). Verify link configuration and, if available, enable or query digital diagnostics (DDM/DOM) through the host system to monitor supply voltage, laser bias current, output power, received power and temperature. Perform standard testing of the optical link after installation to confirm expected reach and performance.
Usage recommendations
Ensure the host device supports 1000BASE-BX-U operation and DDM/DOM if you require remote diagnostics. Use quality single-mode fiber and compatible LC simplex patch cords, keep connectors clean, and follow ESD precautions during handling and insertion to maintain reliable optical performance.
