PROJECT TITLE :

A Bidirectional Wireless-Over-Fiber Transport System

ABSTRACT:

This study proposes and demonstrates a bidirectional wireless-over-fiber (WoF) transport system primarily based on an optical interleaver, a section modulator, and an optical bandpass filter (OBPF)-based phase-modulation-to-intensity-modulation converter which will deliver intensity-modulated 60 GHz millimeter-wave (MMW), 30 GHz microwave (MW), and section-remodulated 15 GHz MW information signals. A broadband light supply, comprising an optoelectronic oscillator theme and an optical signal-to-noise ratio (OSNR) enhancement scheme, is deployed in these bidirectional sixty GHz/thirty GHz/15 GHz WoF transport systems. For downlink transmission, lightweight is promoted optically from a five Gbps/ 15 GHz MW data signal to 5 Gbps/60 GHz MMW and 5 Gbps/thirty GHz MW data signals in fiber–wireless convergence. The downstream light is section remodulated successfully using a five Gbps/15 GHz MW knowledge signal for uplink transmission. Through a thorough examination of such bidirectional 60 GHz/30 GHz/fifteen GHz WoF transport systems, the bit error rate (BER) is observed to perform well over a forty km single-mode fiber and a 4 m RF wireless transmission. This bidirectional 60 GHz/thirty GHz/fifteen GHz WoF transport system is a outstanding alternative not only as a result of of its advancement in integrating optical fiber and RF wireless networks but as a result of of the benefits of communication links for broader bandwidth and better transmission rate still.
