Implementation of a Two-Way Communication Link on Optical Fiber-Free Space Photonics System used in Beam Bridge

In this paper, a two-way communication link is implemented on optical fiber (OF) cable and free-space photonics (FSP) for the outdoor applications like beam bridge. Beam Bridge’s condition is monitored using a uniform fiber-Bragggrating. In case the beam bridge is damaged, the signal propagation will be diverted from OF link to FSP link to restore the communication. A BER (Bit Error Rate) of value 0 (close to an ideal system) and a Quality (Q) factor of value 239.581 has been achieved.
