The Study on Confidential Local Net Telecommunication Applying Polarized Light
The polarity of light transmitted in polarization maintaining optical fibers of a confidential telecommunication system is dependent on artificial and environmental interfere to the fiber. The polarity may be taken as sensing parameter to detect in real time the wiretapping to the telecommunication. The threshold of wiretapping detecting is defined by the bend radius of the fiber, the typical value is 8.5 mm.
