622 Mbit/s‐sixteen‐channel FDM coherent optical transmission system using two‐section MQW DFB‐LDs

Abstract

A light source and optical frequency control t e c h q u e needed for realizing the optical frequency division multiplexing transmission (Optical FDM) I S Random channels could selectively be received with a receiver sensitivity of -39.3 dBm. It was verified that 16 channels of 622 Mbit/s lgh-vision (Japanese standard HDTV) signal could be transmitted through 110 km of 1.3 pm zero dispersion fiber without signal degradation.
