Módulo transceptor de fibra óptica BlueOptics SLC20-DDM-BO 20000 m

The BlueOptics SLC20-DDM-BO 20000 m is a single-mode fiber optic SFP transceiver module designed for point-to-point optical links up to 20,000 metres. Constructed with an aluminium housing and weighing approximately 20 g, the module provides 100BASE-LX optical transmission using LC duplex connectors and operates with 1310 nm transmit and receive wavelengths. The module supports Digital Diagnostic Monitoring (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when used in compatible host hardware.

Advantages

The module follows MSA SFP form-factor and LC duplex connector standards, enabling interoperability with devices that support the Westermo SLC20-DDM 100BASE-LX SFP specification. Built with industry-grade optical components, it offers long reach single-mode transmission and DDM diagnostics to simplify network maintenance and troubleshooting. Its lightweight aluminium housing provides a compact, durable solution for installations where space and reliability are important.

Suitable for

• Long-distance single-mode Ethernet links up to 20 km
• Integration into switches, routers and optical ports that support 100BASE-LX SFP modules
• Industrial and enterprise networks requiring DDM/DOM monitoring

How to use

Insert the SFP transceiver into the appropriate SFP port of a compatible switch, router or media converter while the host device is powered on or off according to the host manufacturer’s guidelines. Connect the module to a single-mode LC duplex fiber patch cord, ensuring correct Tx-to-Rx alignment with the remote transceiver. Verify link status on the host device and, if available, read DDM parameters through the management interface to confirm optical power levels and temperature are within expected ranges.

Recommendations

Ensure that the host device officially supports DDM/DOM if you intend to use diagnostic monitoring features. Use quality single-mode fiber and LC duplex patch cords, maintain clean connector end-faces, and follow proper ESD handling procedures during installation to preserve module lifetime and link performance.
