The Westermo range of Small Form-factor Pluggable (SFP) transceivers covers versions suitable for Gigabit applications.
LC connectors are used as standard due 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 wave length including 1550 nm for extreme distances upto 120 km (74.5 mi) and 1310 nm version for both single (9/125) and multimode cables (50/125 and 62.5/125).
