The module is made of durable metal housing and has an input voltage of 3.3 V. Weighing only 20 g, it is lightweight and easy to install in various networking applications.

## Long description

The BlueOptics FibroLAN B238 SFP transceiver is a compact optical module intended for fiber optic network links. It supports a maximum data transfer rate of 1250 Mbit/s and uses a 1550 nm wavelength for transmission. The module features a metal housing in silver finish, operates from a 3.3 V supply voltage and is lightweight at approximately 20 g, making it suitable for installation in compatible SFP ports on switches, media converters and other network equipment.
Advantages
The BlueOptics FibroLAN B238 combines small form factor and robust metal construction to provide stable optical connectivity. With a 1550 nm wavelength and support for up to 40 km link distance, it meets the needs of longer singlemode fiber runs. Low weight and standard SFP compatibility simplify replacement or expansion of existing network infrastructure without requiring additional power considerations beyond the 3.3 V input.
Suitable for
 Extending singlemode fiber links up to 40 km
 Replacing or upgrading SFP ports in switches and media converters
 Point-to-point optical connections in enterprise and industrial networks
 Optical uplinks where 1250 Mbit/s throughput is required
Key specifications
 Data rate: 1250 Mbit/s
 Wavelength: 1550 nm
 Maximum optical reach: 40,000 m
 Connector type: SX fiber optic connector
 Operating voltage: 3.3 V
 Material and colour: metal housing, silver
 Weight: 20 g
How to use
Ensure the host device supports standard SFP modules and power down equipment if the device manufacturer recommends hot-swap precautions. Align and insert the SFP transceiver into an empty SFP slot until it seats firmly; follow the host device indicators to confirm link status. Connect the appropriate singlemode fiber cable with the SX connector to the transceiver and verify optical link and data throughput. Observe ESD handling guidelines and avoid touching the optical interface; protect the transceiver with dust caps when not connected.
Usage recommendations
Use the module with singlemode fiber rated for 1550 nm and maintain clean connector endfaces to ensure optimal performance. For long-distance links approaching the 40 km specification, verify fiber attenuation and include optical amplification or dispersion compensation only when required by the link budget and network design.
