SFP transceiver modul BlueOptics 740-020425-BO LC 40000 m

The BlueOptics 740-020425-BO LC 40000m is an SFP transceiver module designed for single-mode fiber links with an LC connector and an SFP form factor. It supports long-range optical transmission up to 40,000 meters and is suitable for 1000BASE-BX-U applications that require separate transmit and receive wavelengths over a single fiber. The module is lightweight and compact, intended for integration into switches, routers and other network devices that accept standard SFP modules and conform to MSA specifications.

Advantages

This transceiver offers long-distance single-mode transmission with a compact SFP footprint and LC simplex interface, enabling point-to-point connectivity over up to 40 km without electrical interference. The module is built to MSA mechanical and electrical standards to ensure interoperability with major network platforms. It supports digital diagnostic monitoring (DDM/DOM) for real-time parameters such as supply voltage, laser bias current, output and received power, and temperature to simplify maintenance and fault analysis.

Suitable for

• Long-reach fiber links between switches and routers
• Metro and access network uplinks
• Connections requiring LC simplex single-mode interfaces
• Environments needing DDM/DOM monitoring for link diagnostics

Key specifications

• Connector: LC simplex (single-mode)
• Transmission distance: up to 40,000 m (40 km)
• Supported standard: 1000BASE-BX-U (1.25 Gbps)
• Wavelengths: single-mode bi-directional (separate Tx/Rx wavelengths)
• Digital diagnostics: DDM/DOM (real-time monitoring)
• Product colour: Blue, Grey
• Weight: 0.02 kg

How to use

Install the SFP transceiver into an empty SFP slot on a compatible switch, router or network device until it latches. Connect a single-mode LC patch cable between this module and the remote transceiver, observing correct fibre polarity for the bi-directional pair. Ensure the host device supports 1000BASE-BX-U and DDM/DOM if monitoring is required. After insertion, verify link status in the host system and monitor DDM parameters where available to confirm proper operation.

Recommendations

For optimal performance, use high-quality single‑mode LC patch cords and avoid tight bends or mechanical stress on fiber runs. Confirm compatibility with the host hardware and software settings and verify DDM readings during commissioning to detect impaired links early. Store and handle the transceiver in a clean environment and observe ESD precautions during installation.
