As a settlement for the fiber access, the FTTH is an ideal mode for providing various high-bandwidth value added services including high definition IPTV to broadband users, and KT, the largest incumbent of Korea, started FTTH service from 2005. For FTTH deployment, it needs a cost-effective solution including reliability and maintenance costs. This paper analyzes the characteristics and technical issues for the main components of outside plant in general household area.

FTTH (Fiber to the Home) is constructed with optical devices and optical cables from central office (CO) to subscribers. With FTTH, it is possible to provide service platform in order to meet the customers' emerging demands for more bandwidth/security and diverse IP multimedia applications including high definition (HD) video streaming service. FTTH can provide enough bandwidth from 100Mbps to several Gbps per subscriber. It is also most appropriate network architecture for convergence of communication and broadcasting. So, FTTH is thought the final destination of telecom operators, since it is the fastest and most reliable solution so far and various IP multimedia services are possible through it. In this paper, newly attempted technologies of FTTH construction for apartment complexes using CWDM-PON system are discussed.

The WDM/SCM-FTTH is an advanced optical access Network that can efficiently support various kinds of access network requirements using the WDM and SCM technologies in the near future. In this paper, we propose new network structures of the FTTH(Fiber To The Home) in the WDM(Wavelength Division Multiplexing) and WDM/SCM(Sub-Carrier Multiplexing) FTTH, and evaluate its performance with simulation results for the optical characteristics of the network and the dynamic allocation of bandwidth on demand of the users.

FTTH service has been deployed since last year in the single dwelling unit environment. FTTH based on PON technology has many advantages in OPEX compared to FTTC solutions using the BBx. But this is not the case for the MDU environment where new wiring of the fiber cable in the customer premises network costs a lot of money. The purpose of Hybrid-FTTH is to overcome this problem by preserving the wiring environment of the customer premises environment in MDU but still guarantee the quality of service provided by FTTH. In this thesis, we present Hybrid-FTTH technology, especially focused on the DWDM-PON based Hybrid-FTTH technology and its development status.

가입자단에서의 병목현상 해결과 통신방송융합서비스의 제공을 위해 가입자망 기술은 디지털화된 HFC와 상하향 100Mbps이상의 속도를 제공하는 FTTH(Fiber To The Home)로 진화될 것으로 예측되며, 궁극적으로는 FTTH로 수렴될 것으로 전망되고 있다. FTTH는 통신과 방송이 융합된 다양한 신규서비스로 새로운 수익을 창출할 것으로 기대되나, 대규모 투자가 필요한 상황에서 정확한 수요 예측은 통신 회사들의 네트워크 구축 관련 의사결정에 필수적인 요인이다. 이를 위해 본 논문에서는 경쟁서비스로 천이가 용이한 통신서비스의 특징을 고려하여 FTTH의 수요예측을 실시하였다. 1차 전문가 설문을 통해 서비스간 전이형태를 모형화하였으며, 이를 토대로 FTTH 서비스로의 천이에 의해 추가적인 확산이 일어나는 변형된 Bass모형을 제안하였다. FTTH 서비스의 확산요인을 분석한 후 이를 토대로 2차 전문가 설문을 통해 각 계수를 추정하였다.

Recently, broadband access networks have been competitively deployed all over the world with the development of various multimedia services for such a network. ETRI(Electronics and Telecommunications Research Institute) built the FTTH(Fiber-To-the-Home) service center to develop a next-generation equipment and a high-quality service/platform as well as to promote domestic industry in the field of optical communication. The FTTH service center has a variety of test equipments such as FTTH standard testbed for a BMT(bench mark test), a network operation center, and IPTV service equipments. Also, ETRI deployed a new type of commercial optical access networks cooperating with ISP(Internet Service Provider). This paper presents the performance evaluation of FTTH E-PON(Ethernet Passive Optical Network) system as a platform for TPS(Triple Play Service) based on QoS(Quality of Service) and QoE(Quality of Expericence) issues. This FTTH E-PON system is successfully demonstrated as an optical access network system by commercial network service provider and the FTTH service center of ETRI.
