光纤延迟线
产品描述:
光纤延迟线由输入和输出光纤准直器组成,使光线射入自由空间并重新入射到光纤中。光在自由空间的传输距离既可通过输入输出光学器件间的距离也可通过可移动的反射器来精确控制。两种情况下,改变光传播的距离可以控制通过器件的延迟时间。
共有单模、多模和保偏光纤可供选择。OZ Opitcs 在制作保偏光纤组件和跳线时一般都采用熊猫保偏光纤。然而,OZ Optics 也可使用其他类型的保偏光纤结构。我们也准备了一些可替换的光纤可供选择,请联系我们的销售部门。如有需要,我们愿意用客户提供的光纤生产装置。
延迟线由手动和电控型可供选择。手动延迟线利用一个螺丝和千分尺来调节间距。电控型利用一个带编码的伺服电机来监测移动。设备达到了亚微米的分辨率(<0.003 ps)。 延迟线可通过带有RS-232接口的计算机或手动TTL输入信号来控制,非常简单方便。此设备已校准,并提供皮秒量级的延迟。新微型延迟线采用最小化的封装,提供13 皮秒的延迟。该装置占据了比普通跳线连接装置多一点的空间,并且非常容易调节和锁定。

A customer is building a polarization mode dispersion compensator using a polarization maintaining electrically controlled delay line and computer interface. The delays in their system are 50 picoseconds or less. His system is sensitive to both insertion losses and return losses, so a low return loss device is needed.
