OBS 망용 2 차 하모닉 SCM 광헤더와 페이로드 신호간의 선형 누화 제어

Abstract

We demonstrate a second harmonic subcarrier generation(SH-SCG) technique for subcarrier multiplexed (SCM) header, which is required to suppress linear crosstalk to payload. To resolve this problem, we increase the spectral distance between payload and header signal using the SH-SCG technique and suppress the optical carrier component of header signal. The back-to-back BER estimation of 2.5-Gb/s payload shows that the power penalty induced by the linear crosstalk with 155-Mb/s header is 0.3dB at a BER of 10-9.
