Multichannel AM-VSB television signal transmission using an erbium-doped optical fiber power amplifier
TL;DR: In this paper, the use of an erbium-doped optical fiber power amplifier in a multichannel amplitude-modulated vestigial-sideband CATV transmission system for potential subscriber loop applications is discussed.
Journal ArticleDOI
160-channel FM-video transmission using optical FM/FDM and subcarrier multiplexing and an erbium doped optical fibre amplifier
TL;DR: In this paper, a total of 16 DFB lasers with 10 GHz frequency spacing were combined to transport 160-channel FM television signals to 16 locations; each link distance was 9 km with an average power margin of 7.5 dB.

High gain limiting erbium-doped fibre amplifier with over 30 dB dynamic range
TL;DR: In this article, a limiting optical amplifier is demonstrated using three cascaded stages of erbium-doped fiber amplifiers with a constant output power of +12.9 dBm for an input power ranging from −30 to 1.5 dBm.

Abstract: By using an in-line erbium-doped fiber amplifier with a net gain of 20.5 dB, it was possible to transmit an 11 Gb/s NRZ signal over 151 km of dispersion-shifted fiber. The bit rate distance product of 1.66 Tb/s-km obtained for a single-laser link with optical amplifiers experiment is a substantial improvement over the previous record of 1.03 Tb/s-km. The measurements indicate that new systems optimization procedures, as well as the incorporation of additional optical isolators, are required in order to assure stable operation with minimum system degradations. >
