Research output: Contribution to journalArticlepeer-review


We propose and demonstrate, for the first time, a bidirectional externally modulated NTSC AM-VSB 77-channel transport system over an 80-km large effective area fiber (LEAF) which used bidirectional transport and dense-wavelength-division-multiplexing (DWDM), techniques. By comparing with the system link with a transmission length of 80 km single-mode fiber (SMF) and truewave fiber (TWF), not only channel capacity was doubling, but also good carrier-to-noise ratio (CNR) ≥ 50 dB, composite second order (CSO) ≥ 68 dB and composite triple beat (CTB) ≥ 64 dB performances were obtained in our proposed system after an 80-km LEAF transport.
