Abstract
본 논문에서는 파장분할 다중방식의 수동형 광 가입자망(WDM-PON: Wavelength Division Multiplexing - Passive Optical Network)에서 매우 구조가 간단하고 저비용으로 구현 가능한 방송신호 전송 방법을 제안한다. 이는 하나의 광대역 증폭된 자발 광원(Amplified Spontaneous Emission: ASE)과 편광 독립 반사형 반도체 광 증폭기(Polarization Independent-Reflective Semiconductor Optical Amplifier: PI-RSOA) 만으로 구현이 가능하기 때문이다. 채널당 1.25 Gb/s 속도에서 24개의 가입자 채널에 대해 30 Km 이상의 방송 신호 전송 시, 무오류(error-free) 성능을 갖는 것을 실험적으로 증명하였다. In this paper, we propose a new method for broadcasting in a WDM-PON system which has the merits of a simple and cost effective structure. It can be constructed using only an ASE (Amplified Spontaneous Emission) light source and a PI-RSOA (Polarization Independent - Reflective Semiconductor Optical Amplifier). Error-free broadcast signal transmission over 30 Km for 24 channels at 1.25 Gb/s has been successfully demonstrated.
