Abstract :
In order to break the limitations of centralized wireless communication system, a separating terahertz wireless communication system adopting Radio over Fiber (ROF) technique is designed in the paper. But in the system, dispersion can cause serious transmission attenuation and code-edge time-shift then decrease the data signal quality. In order to solve the problem, based on studying the relationship between SMF fiber dispersion and transmission attenuation, transmission distance, a method using OCS modulation to increase SMF transmission distance is put forward. And in OCS, that is code-edge time-shift which decreases the quality of data signal in optical terahertz wave after going through SMF. From theoretic calculation and eye pattern analysis, we got the maxim transmission distance of SMF fiber is up to 1.5km.
