## Summary description

The BlueOptics SLC20-DDM-BO is a fiber optic SFP transceiver module designed for high-speed data transmission. It supports a maximum transfer distance of 20000 m and is made of durable aluminum, weighing only 20 g. This module is ideal for networking applications requiring reliable and efficient data transfer.

## Long description

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
Key specifications
Form factor: SFP (Small Form-factor Pluggable)
Optical mode: Single-mode fiber
Connector type: LC duplex
Wavelength: 1310 nm (Tx and Rx)
Maximum transmission distance: 20,000 m (20 km)
Supported protocol: 100BASE-LX Ethernet
Digital diagnostics: DDM / DOM (MSA SFF-8472 compatible)
Housing material: Aluminium
Weight: approx. 0.02 kg
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.
Usage 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.
