초록

최근 비디오 컨텐츠 및 융합 서비스들을 위한 대역 확보가 관건으로 떠오르고 있는 가운데 기존 케이블 사업자들은 Hybrid Fiber Coaxial(HFC) 네트워크를 통해 방송과 IP 기반 서비스를 수행하고 있다. 하지만 HFC 네트워크는 MPEG 기반의 방송 서비스를 목적으로 하기 때문에, 대역확보에 어려움이 있다. 따라서 네트워크 광대역화를 위한 방법이 필요하며 그 중 Radio Frequency over Glass(RFoG) 는 HFC 네트워크가 가지는 대역폭의 한계를 극복하고, 구조를 단순화 시키는 장점을 가지고 있다. 본 논문에서는 RFoG의 특성과 기준, 서비스 품질 등을 살펴보고, 성능 평가를 통해 HFC 대비 RFoG의 장점을 확인한다.

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.
