摘要
本文分析了二级有线电视光纤网“光/电/光转换中继方式”和“光放大器中继方式”两种联网方案,提出了在临频系统近于满载时采用1550nm系统“光放大器中继方式”的优选方案,赢得电缆分配系统分配比例裕量.对于1550nm参铒光纤放大器EDFA性能亦做了介绍.
This paper analyses two network schemes of two stage CATV optical network , that is ‘ the optical/electronic/ optical relay method’and ‘the optical amplifier relay method ’.And it suggests a favorable layout which adopt the 1550 nm optical amplifier relay method when the adjacent frequency system reached full channels . The layout makes the cable distributing system redundant in distribution. This paper presents the details of the EDFA too.
