ODW-720-F2
The ODW-720-F2 has been designed to allow the use of fibre optic cables on RS-232 networks. 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. Both multidrop networks and redundant rings can be formed
using a mixture of transceiver types.
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 a second
data channel if necessary.
Large ring networks can be created to provide network resilience to guarantee system functionality, even if a cable is
damaged. The ring recovery time ensures that the network devices are not aware of the failure. The fault contact
provides a method to communicate network failures.
