## Summary description

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

## Long description

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.
Suitable for
 Gigabit Ethernet links over single-mode fiber
 Point-to-point metropolitan or campus links up to 20 km
 Use in switches, routers, storage systems and other network appliances with SFP ports
 Remote optical link monitoring and maintenance when DDM is supported
Key specifications
 Interface type: SFP (small form-factor pluggable)
 Data rate: up to 1250 Mbit/s
 Fiber type: single-mode
 Wavelengths: transmit and receive pair suitable for BX-U operation (bi-directional over single fiber)
 Connector: LC simplex
 Maximum reach: up to 20 km
 Housing: metal (silver color)
 Digital Diagnostics Monitoring (DDM/DOM): supported when host hardware provides DDM support
 Compliance: MSA-compatible mechanical and electrical form factor
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.
Usage 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.
