SFP transceiver module BlueOptics SFP-BXU34-40KM-EN-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-EN-BO 1250 Mbit/s is a small form-factor pluggable (SFP) fiber optic transceiver module designed for single‑port installations that require reliable point-to-point data links. Housed in a metal casing and weighing just 20 g, this module supports a maximum data transfer rate of 1250 Mbit/s and is engineered for long service life with a mean time between failures (MTBF) of 1,000,000 hours. Its compact silver metal housing makes it compatible with standard SFP slots in switches, routers and media converters that accept SFP transceivers.

Advantages

The metal housing provides mechanical robustness and thermal dissipation for stable operation in populated chassis or outdoor enclosures. With a lightweight design and standard SFP form factor, the module is easy to install and hot-swappable in supported equipment. The specified maximum data rate of 1250 Mbit/s makes it suitable for common fast Ethernet and legacy fiber applications while the high MTBF indicates long-term reliability and reduced maintenance frequency.

Key specifications

How to use

Insert the module into a compatible SFP slot until it latches; confirm link status via the host device indicators or management interface. Ensure fiber connectors and cables are clean and properly aligned to the module’s optical interface before powering the link. Use manufacturer or chassis documentation to verify supported wavelengths and duplex settings if applicable. To remove, disengage the latch and pull the module straight out to avoid damaging the host port.

Recommendations

Operate the transceiver within the host equipment’s specified temperature and optical power ranges. Keep dust caps on the optical ports when the module is not in use, avoid mechanical stress on connected fibers, and verify compatibility with the host device’s SFP slot and network configuration to ensure stable 1250 Mbit/s links.
