linking optic fibre to a scantronic 9751?

[bellman]

Just to clear up a quick misconception.... fibre is very secure... its actually more secure than UTP or any other connections as it cannot be easily tapped (since its light!). This is why for any secure data connections companies will use Fibre links.

Therefore the way to make this connection secure is to allways detect light, and if no light is detected then trigger an alarm.

Dale is quite right, fibre is inherantly secure. (I also used to fit it)

but in the proposed aplication it cannot be used unless it can indicate 3 states.

normal, alarm AND tamper
