LC/APC Male Female Attenuator Fixed Flanged Type 20dB Model: Fiber-Attenuator-LC/APC-20dB

Fiber attenuator LC/APC-20dB LC/APC male female attenuator fixed flanged type 20dB, is a full wave, active filter with a high insertion loss and high insertion bandwidth. The attenuation mechanism of the fiber optic attenuator is mechanical and basically consists of transverse movement of the fiber core to change both light power and the distribution of light at different arrival angles. Thus, the system can be used in a broad range of applications such as laser windows or light switches. If you are looking for fiber optic attenuator, please don’t hesitate to contact us. We will be glad to provide you with a quick quotation!
