介绍了国内首次研制的光缆ＣＡＴＶ用１．３μｍＤＦＢ激光器组件。组件工作频带达到１ＧＨｚ，带内起伏＜１ｄＢ；组件的ＲＩＮ＜－１５３ｄＢ／Ｈｚ；出纤光功率＞２ｍＷ；载噪比ＣＮＲ＞５０ｄＢ。首次实现用低反射尖锥端光纤和ＤＦＢ激光器耦合。初步研究了ＤＦＢ激光器的非线性补偿电路，使互调改善了近８ｄＢ。
The 1.3μmDFB laser module for CATV cable was first introduced in China. Component operating band to 1GHz, with less than 1dB band; component RIN <-153dB / Hz; fiber optic power output> 2mW; CNR> 50dB. For the first time, low-reflex tapered-end fibers and DFB lasers were coupled. Preliminary study of the DFB laser nonlinear compensation circuit, so that intermodulation improved by nearly 8dB.
