1.描述DESCRIPTION 梓冠光電的一款新的微型可調衰減器,可應用于C或L波段。該衰減器具有良好的波長平坦度相關性 ,低偏振相關損耗(PDL),并提高了溫度穩定性。衰減器為光功率提供了一種經濟的解決方案。反射光學允許同側跳線退出,并使面板易于安裝。衰減器采用先進的梯度中性密度濾波器作為衰減元件。調整是通過步進電機的反饋控制終端。步進電機的驅動器以統一的步長上下移動電機,提供精細的分辨率。鎖定操作是一個標準功能;移除驅動電壓后,保留最近的衰減設置?蛇x的電阻讀數用于過濾器定位。衰減器原理圖如圖1所示。 Zg introduces a new miniature variable attenuator for application in either the C or L band. The attenuator offers excellent wavelength dependence and ripple, low polarization dependent loss (PDL), and improved thermal stability. The attenuator provides an economical solution to managing optical power. Reflective optics permit same-side jumper exit and enable easy panel mounting. The attenuator uses an advanced graded neutral density filter as its attenuating element. Adjustment is through a stepper motor with feedback control terminal. The driver for the stepper motor moves the motor up or down in uniform step sizes, offering fine resolution. Latching operation is a standard feature; upon removal of the drive voltage, the most recent attenuation setting is retained. An optional resistance readout for filter location purposes is available. The schematic figure of the attenuator is shown in figure 1.
