Abstract
We discuss the CNR performance and optical link-budget optimization in 1550-nm EDFA-based video lightwave transmission systems for video trunking applications. The operating point of the in-line EDFAs was determined by balancing the requirement for achieving a targeted CNR and a largest-possible link-budget. In addition, a 120-km multichannel AM-VSB/256-QAM video lightwave trunking system using two in-line EDFAs was demonstrated. At the optimum plus 3-dBm EDFA's input optical power, the 1550-nm AM/QAM video lightwave trunking system offers an AM CNR greater than 49-dB with CSO and CTB distortions less than minus 65- dBc as well as nearly error-free 256-QAM transmission. The overall system link-budget was greater than 35-dB.
