## Summary description

The BlueOptics SFP-BXD43-20KM-QL-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. This module is designed for reliable data transmission over long distances, making it ideal for network applications.

## Long description

The BlueOptics SFP-BXD43-20KM-QL-BO network transceiver module Fiber optic 1250 Mbit/s is a small-form pluggable (SFP) fiber optic module intended for single-channel optical links. With a metal housing and a compact SFP form factor, this module supports a maximum data rate of 1250 Mbit/s and is designed for reliable data transmission over extended distances. It is suitable for integration into switches, routers and media converters that accept SFP modules and support optical interfaces.
Advantages
The metal housing provides mechanical durability and improved heat dissipation compared to plastic enclosures. The SFP form factor enables hot-pluggable insertion into compatible networking equipment without powering down the system. Support for a 1250 Mbit/s line rate ensures compatibility with standard optical network interfaces used in Ethernet and telecom applications. The module’s lightweight construction makes it easy to handle and install in racks or cabinets.
Suitable for
Point-to-point fiber links between switches or routers
Metro and access networks requiring optical SFP modules
Media converters and small form-factor networking devices
Environments where a compact, hot-pluggable optical transceiver is needed
Key specifications
Interface type: SFP (Small Form-factor Pluggable)
Maximum data transfer rate: 1250 Mbit/s
Housing: metal for mechanical protection and thermal conduction
Weight: approximately 0.02 kg
Form factor: SFP module suitable for standard SFP ports
How to use
Ensure the host device supports SFP optical modules and that the correct optical fibre type and connector are used for the intended link. With the host device powered on or following the vendor’s hot-swap procedure, insert the SFP module into an available SFP slot until it clicks into place. Connect the fibre optic cable to the module’s optical port, observing correct transmitter/receiver orientation and connector cleanliness. Configure the network device’s interface settings as required by your network equipment to enable the optical link at the supported data rate.
Usage recommendations
Inspect and clean fiber connectors before insertion, avoid excessive bending of fiber cables, and verify compatibility with the host equipment’s supported SFP features. Use appropriate ESD precautions when handling the module and follow vendor-specific guidelines for firmware or interface configuration.
