SFP transceiver BlueOptics FibroLAN B238 1250 Mbit/s 1550 nm

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.

Key specifications

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.

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.
