“…The synchronization performance is usually evaluated through the calculation of different quantities, such as the synchronization error or the correlation coefficient [22]. In our case, we calculate the chaotic carrier cancellation -expressed in dB, which expresses practically the subtraction efficiency, between the transmitter and receiver chaotic outputs [19]. The higher the chaos cancellation, the better the synchronization performance will be.…”

The optical chaotic communication system using open-loop fiber transmission is studied under strong injection conditions. The optical chaotic communication system with open-loop configuration is studied using fiber transmission under strong injection conditions. The performances of fiber links composed of two types of fiber segments in different dispersion compensation maps are compared by testing the quality of the recovered message with different bit rates and encrypted by chaotic modulation (CM) or chaotic shift keying (CSK). The result indicates that the performance of the pre-compensation map is always worst. Two types of symmetrical maps are identical whatever the encryption method and bit-rate of message are. For the transmitting and the recovering of message of lower bit rate (1 Gb/s), the post-compensation map is the best scheme. However, for the message of higher bit rate (2.5 Gb/s), the parameters in communication system need to be modified properly in order to adapt to the high-speed application. Meanwhile, two types of symmetrical maps are the best scheme. In addition, the CM method is superior to the CSK method for high-speed applications. It is in accordance with the result in a back-to-back configuration system.

“…The bandwidth of such chaotic carriers may extend even up to tens of gigahertz, making them ideal candidates for high bitrate message encryption. Experimental observation of chaos synchronization has been reported for all the above systems [23][24][25][26].…”

A thorough study of an all-optical chaotic communication system, including experimental realization real-world testing and performance characterization through bit-error-rate analysis, is presented. Pseudorandom data that are effectively encrypted in the chaotic emitter and sent for transmission are recovered at the receiver with bit-error-rate (BER) values as low as 10 -7 for 1 Gb/s data rate. Different data code lengths and bit-rates at the Gb/s region have been tested. Optical transmission using 100km fiber spools in an in-situ experiment and 120km in an installed optical network showed that chaotic communication systems does not act as a considerably deteriorating factor in the final performance.
