摘要
研究一种温度自适应可调光衰减器控制方法,基于不同温度下可调光衰减器的温度特性曲线,提出一种温度自适应控制方法。提高了温度变化范围大时可调光衰减器的控制精度。测试结果表明,本设计可调光衰减器能够提高控制精度,温度范围-25℃~75℃衰减误差小于0.1dB。
A temperature adaptive tunable optical attenuator control method is designed. Based on the tempera. ture characteristic curve of the tunable optical attenuator under different temperature, a temperature adaptive con. trol method is proposed. The control precision of the tunable optical attenuator is improved when the temperature range is large. Testing results show that the control precision of the attenuator is improved, and the temperature rang. es is from -25 ℃ to 75 ℃, the attenuation error is less than 0.1 dB.
