The ODW-720-F1 has been designed to allow RS-232 protocols to be transmitted point-to-point over a fibre optic link.

The design allows the use of a range of Westermo verified SFP (Small Form Pluggable) transceivers which can provide solutions with, for example, only a single fibre or distances up to 120 km.

This unit has been designed for industrial use where the requirement is for a long and reliable service life, in a harsh environment. To ensure this reliable operation we manufacture using the highest quality components.

The ODW-720 draws on Westermo’s many years of knowledge of serial protocols and can even transmit the RTS/CTS hardware controls if required.

The ODW is simple to install, being small, with a simple integral DIN rail clip. The unit is totally transparent to any data rate so no configuration is needed.

The comprehensive LEDs provide a quick and easy way of detecting any network problems that may be encountered.
