ODW-700 Fiber Converter Series

Westermo ODW-700 Series Fiber Converters, PROFIBUS DP, RS-232 or RS-422/485, Point to Multipoint/Ring, Serial data up to 12 Mbit/s, 2 x SFP Slots (SFP Modules Sold Separately) -40 to +70 deg.C, 10-60 VDC. (Please Specify Model.)

ODW-700 Series Ring/Multidrop Fiber Converter

The ODW-700 series has been designed to allow PROFIBUS DP, RS-232 or RS-422/485 data to be transmitted over fiber optic links in point-to-point, multidrop or redundant ring 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 fiber or distances up to 120 km.

The units have 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, it is manufactured using the highest quality components.

The ODW-710 can be used on all PROFIBUS DP networks to extend the operational network size beyond the normal constraints of the copper cable. All the data rates defined in EN 50170 are supported.

The ODW-720 and ODW-730 draws on Westermo’s many years of knowledge of serial protocols, with the ODW-720 being able to transmit RS-232 serial data, even the RTS/CTS hardware controls if required. The ODW-730 supports RS-422/485 and can be used on both synchronous and asynchronous data streams, with switch selectable termination circuits that save the need for external terminating resistors.

The F1 variants are excellent for cost effectively creating point-to-point networks with their single fibre port. Meanwhile, the F2 variants offer flexible multidrop and redundant ring solutions to be created with the dual fibre ports. 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.

The ODW-700 series is simple to install, being small, with an easy-to-use integral DIN rail clip. The unit are totally transparent to any data rate, meaning configuration is not needed.
