최근 유무선 데이터 트래픽 증가에 따른 추가 설비 비용 등의 증대는 수익성이 정체된 통신 산업체에 부담을 가중시키고 있다. 폭증하는 신규 서비스 대응과 산업체의 수익성을 동시에 확보하기 위해서 기존 망자원의 효율화 증대 및 고성능화하기 위한 방안으로 Optical SDN 시스템 및 부품 기술경쟁이 심화되고 있다. 본고에서는 이러한 요구 사항을 해결하고 국내 광네트워크 산업의 재도약을 위한 광부품 기술개발로써, 미래부 주관 차세 대통신 네트워크 산업 원천기술개발 사업인 ‘Optical SDN 구현을 위한 Metro용 Port agnostic 광송수신 기술 개발’에 대한 기술을 소개하고 과제의 주요 연구 목표 및 내용인 100G coherent 광송수신 기술, 핵심 요소 부품기술에 대하여 소개함으로써, 향후 과제에서 개발 진행 중인 기술과 연계된 국내 광부품 산업체들이 고려해야할 주요 글로벌 기술 이슈 사항들과 본 과제에서 중점적으로 수행중인 내용을 간략히 소개하고자 한다.
