RoF using Subcarrier Multiplexing/Amplitude Shift Keying (SCM/ASK) for providing Broadband Wireless Access

Abstract

Fiber optics transmission system refers that it carries information in the form of optical signal using 1550 nm, which are effective in view of high throughput and reliability for long distance network. It uses TDM multiplexing technology that combine multiple signals which are available as electrical enable to increase throughput by minimizing an investment in medium. This paper deals with the twin concepts of optical transmission networking and Radio transmission technology. When user have specific mobility requirement, then we may need of implementing wireless in access network so that user requirement can be achieved. Optical transmission networking is implemented with TDM devices like TM, ADM, R/R, DXC and fiber optics and Radio transmission is implemented with radio devices like Modulator , hybrid coupler, circulator and SCM ASK for providing wireless broadband. With the increasing deployment and growth in transport networks based on TDM technology, solving the classic network design and planning problem of optimizing cost and scalability for given traffic requirements becomes ever critical. The concept is implemented in network to increase the bandwidth and also to offer the limited mobility to user and network is optimized through BER, Optical spectrum analyzer, Optical power meter visualize. Finally network gets extended in coverage area and maximizing bandwidth by ensuring the performance parameters of network such as latency, reliability, SNR.
