Abstract

1.55 μm 80 channel AM CATV video lightwave systems are investigated using 1480 nm locally- and remotely-pumped amplified techniques far the first time. Satisfactory CNR performances of 45 dB with CSO/CTB of 61:70 dB are achieved for a locally-pumped repeatered system over a standard 127 km singlemode fibre. Based on the repeatered technique. System design and operation considerations of the remotely-pumped repeaterless system are also discussed. Repeaterless systems may find important applications for inter-islands and island-hopping with no active components allowed
