The LNF-320 is a common-mode filter designed to reduce noise on laser diodes driven by ILX Lightwave current sources using the standard 9-pin D-sub connector. The filter is designed to be used in series with the laser cable. A current source is a naturally high output impedance device, resulting in an increased susceptibility to noise pickup. The use of a filter will reduce the AC impedance and, therefore, reduce the radiated noise pickup at the output of the current source. This will not affect the DC performance of the current source. A common-mode structure is used to isolate the laser (load) ground from the current source ground. This will lessen noise induced by system ground loops.

LNF-320是一种共模滤波器，设计用于降低由ILX光波电流源驱动的激光二极管上的噪声，使用标准的9引脚D-sub连接器。该滤波器设计用于与激光电缆串联使用。电流源是一种自然的高输出阻抗器件，导致对噪声拾取的敏感性增加。使用滤波器将减少交流阻抗，因此，减少辐射噪声皮卡在当前源的输出。这不会影响电流源的直流性能。共模结构用于将激光(负载)接地与当前源接地隔离。这将减少系统接地回路引起的噪音。
