Fiber optic transceiver module BlueOptics MGB-TLB20-BO SFP 20000 m

The BlueOptics MGB-TLB20-BO SFP 20000 m is a fiber optic transceiver module designed for single-mode links up to 20 kilometers. Housed in an aluminium body and weighing 20 g, this SFP module supports 1000BASE-BX-D operation with an LC simplex connector and separate transmitter and receiver wavelengths for single-fiber bidirectional transmission. The module follows MSA form-factor and electrical specifications for straightforward integration into compatible networking equipment.

Advantages

The module delivers long-reach optical connectivity up to 20,000 m while maintaining compatibility with MSA-compliant SFP ports. Its aluminium housing provides mechanical protection and thermal dissipation in rack-mounted or field installations. The transceiver is suitable for Gigabit Ethernet, Fibre Channel over Ethernet and SDH/SONET applications at up to 1.25 Gbps and supports digital diagnostic monitoring where the host hardware implements DDM/DOM.

Suitable for

• Single-mode fiber links requiring long distance connectivity (up to 20 km)
• Gigabit Ethernet uplinks between switches and routers
• Interconnection of data center equipment, storage systems and telecom devices
• Environments that require LC simplex connectors and bidirectional single-fiber transmission

How to use

Install the BlueOptics MGB-TLB20-BO into an empty SFP slot of a compatible switch, router or other network device while the device is powered off or following the manufacturer's hot-swap guidelines. Connect an appropriate single-mode LC simplex patch cable or patch panel, ensuring correct polarity for bidirectional single-fiber operation. Verify link status and module recognition in the host device's interface; enable DDM/DOM monitoring if the platform supports this function. Follow standard ESD precautions when handling the module and keep the optical connector dust caps in place until connection.

Recommendations

For optimal performance use single-mode fiber rated for long-distance links and high-quality LC simplex patch cords. Verify host compatibility for 1000BASE-BX-D and DDM support prior to deployment. Regularly inspect and clean connectors to maintain signal quality and avoid optical power loss.
