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 cer tified 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). 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 par t 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) / fibre attenuation (db) per km.

Signal loss = splice attenuation x number of splices + connector attenuation x number of connectors + safety margin. Splice, connector and fibre attenuation can be found on article data sheets.

By calculating the maximum distance based on power budget a LC2 multimode transceiver can operate up to 5 km (3.1 mi).
