Universal Fiber Optic Interface Converter

Glass fiber optic transmission lines are the solution of choice 
when you need to implement absolutely noise-free serial  
data transmission over long distances and/or in noisy  
environments.

Whereas the attenuation with plastic fiber optics places a limit 
of maximum 100 meters on the attainable cable length, the 
distances achievable with glass fiber optics are significantly 
greater and at a comparable cable cost.

The fiber-optic solution offers another significant advanta-
ge: The data transfer is carried out with minimal delay and  
enables the processing of real-time protocols.

Wiesemann & Theis offers an entire family of various fiber 
optic interfaces that allow you to convert critical I/O ports 
or serial ports into an optical port for connecting glass fiber 
optic cable.

This interface family is described on the following pages 
along with the corresponding technical data and including 
connection examples.

For up-to-date information on new developments, see our 
Internet site at http://www.wut.de or check the e-mail 
short notices at the W&T Interface Club, which you can also  
subscribe to from the W&T Homepage.
