## Summary description

The BlueOptics SFP-BXU34-20KM-VA-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-VA-BO is a Single-Mode fiber optic SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data transfer rate of 1250 Mbit/s. The module uses an LC simplex connector and supports unidirectional transmit/receive operation on a single fiber, with nominal wavelengths of 1490 nm (transmit) and 1310 nm (receive). Housed in a metal casing and weighing approximately 20 g, it is intended for use in network equipment that accepts MSA-compliant SFP modules and supports Digital Diagnostics Monitoring (DDM) / Digital Optical Monitoring (DOM).
Advantages
The transceiver offers MSA-compliant mechanical and electrical interfaces for broad interoperability with switches, routers and storage systems that support SFP modules. Its metal housing provides mechanical durability and thermal stability, while the integrated DDM/DOM capability enables real-time monitoring of supply voltage, temperature, laser bias current, transmit power and receive power for easier troubleshooting and maintenance. With an MTBF of around 1,000,000 hours and a compact SFP form factor, the module supports long-term deployment in high-availability links up to 20 km over single-mode fiber.
Suitable for
Gigabit Ethernet links (1000BASE-BX-U) over single-mode fiber
Interconnections between network devices such as switches and routers
FTTx and long-reach access networks up to 20 km
Storage networking and carrier/metro aggregation applications
Key specifications
Interface type: SFP (MSA-compliant)
Link standard: 1000BASE-BX-U / 1.25 Gbit/s
Wavelengths: Tx 1490 nm / Rx 1310 nm
Fiber type: Single-mode
Connector: LC simplex
Maximum reach: up to 20 km (typical single-mode fiber)
Housing: metal
Weight: approximately 0.02 kg
Digital Diagnostics Monitoring (DDM/DOM): supported (if host hardware supports DDM)
How to use
Before installation, verify that the host device supports MSA-compliant SFP transceivers and DDM if diagnostic readings are required. Insert the module into the SFP slot of the switch, router or media converter until it latches; connect an LC simplex single-mode patch cable between this transceiver and the corresponding remote transceiver. Ensure transmit and receive directions on the single fiber are correctly paired (Tx to Rx). Configure the host interface for 1 Gbps operation if needed and confirm link status through the device management interface. If DDM is used, access diagnostic parameters through the host management system to check voltage, temperature and optical power values.
Usage recommendations
Use certified single-mode patch cables and maintain clean LC connectors to preserve link performance. Verify compatibility with the specific hardware vendor and model before deployment and, when possible, perform a test link to confirm full functionality and DDM reporting. Avoid inserting or removing the module under heavy optical power and follow ESD precautions during handling.
