Abstract

As the demand for broadband multimedia including the Internet explosively increases, the advancement of the subscriber network is becoming the biggest issue in the telecommunication industry due to the surge of data traffic caused by the emergence of new services such as smart phone, IPTV, VoIP, VOD and cloud services. In this paper, we have developed WDM(Wavelength Division Multiplexing)-PON(passive optical network) based on the 1-Gigabit Reach Externder (RE) technique to reduce optical core. Particularly, in order to strengthen the market competitiveness, we considered low cost, miniaturization, integration technique, and low power of optical parts. In addition, we have developed a batch system by integrating all techniques for reliability, remote management through the development of transmission distance extension and development of capacity increase of optical line by using RE technology in existing PON network. Based on system interworking with existing commercial 1G PON devices, it can be worthy of achievement of wide nationalization and optical core reduction by using this developed system. Based on these results, we are studying development of 10G PON technology.

인터넷을 비롯한 광대역 멀티미디어 수요가 폭발적으로 증가함에 따라 스마트폰, IPTV, VoIP, VOD, 클라우드 등의 새로운 서비스의 등장으로 유발된 데이터 통신량의 폭주로 가입자망의 고도화가 통신 산업에서 가장 큰 이슈가 되고 있다. 본 연구에서는 파장분할다중방식(Wavelength Division Multiplexing, WDM) 수동형 광가입자망(Passive Optical Network, PON)의 국사 광역화와 광코어 절감을 위한 1기가급 Reach Extender(RE) 기술에 대한 개발을 시도하였다. 특히, 시장 경쟁력을 강화하기 위하여 광부품의 저가화와 소형화, 집적화, 소비 전력 폭주를 대처하기 위한 저전력화 등을 고려하였다. 또한, 기존 PON망에 RE 기술을 이용하여 전송 거리 확장 기술 개발 및 광선로의 용량 증가 기술 개발을 통한 신뢰성 기술, 원격관리 기술을 통합하여 일괄 시스템 개발을 완료하였다. 개발 시스템을 이용하여 기존 상용 1G PON 장비들과의 시스템 연동을 기반으로 개발 시스템을 이용한 국사 광역화와 광코어 절감을 이룬 것에 그 가치를 둘 수 있다. 본 연구를 기반으로 10G PON 기술 개발에 대한 연구를 진행 중이다.
