Abstract
Recently, cable operators are providing broadcast and IP based services using Hybrid Fiber Coaxial(HFC) networks while securing frequency band for video contents and convergence services are becoming an important issue. But, HFC networks have difficulty of securing frequency band, because they are used for broadcasting service based on MPEG. Therefore, it is necessary to find out a method to go broadband. Radio Frequency over Glass(RFoG), one of the methods to go broadband, is advantageous in the sense that it can overcome bandwidth limit and simplifies the structure. In this paper, we find characteristic and standard of RFoG and services. And we also find advantage of RFoG by evaluating performance.
