Westermo SLC20-DDM SFP Module

The Westermo range of Small Form-factor Pluggable (SFP) transceivers covers versions suitable for Gigabit applications.

LC connectors are used as standard due to their small size. These transceivers have been verified to meet the Westermo environmental specification and can operate in a range of different Westermo products in harsh industrial applications. The transceivers are coded to allow confirmation that certified versions have been installed.

Versions are available with different wavelengths including 1550 nm for extreme distances up to 120 km (74.5 mi) and 1310 nm versions for both single (9/125) and multimode cables (50/125 and 62.5/125). In applications where only a single fibre core is available a Bi-Directional (BiDi) transceiver can be used.

The different transceiver options are marked with an indicative range as a part of the transceiver description. This is the specified distance when the transceiver is used in Gbit applications. For the ODW series, the maximum distance (km) can be calculated with the formula: Power budget (dB) – signal loss (dB) / fiber attenuation (db) per km.
