摘要
本文介绍了掺铒氟化物光纤的性能 ,并对光几何参数非常接近的EDSFA和EDFFA在AM -VSBCATV系统内进行了对比 ,在对比过程中采用了两只不同波长 (1542nm和1561nm)。
In this paper, the performance of Erbium-doped fluozirconate optical fiber is introduced, and the EDSFA and EDFFA in the AM-VSB CATV system, which have very close optical geometric parameters, are compared using two analog DFB signal lasers that are different in wavelength(1542nm and 1561nm) and chirp characteristics.
