Fiber Optic Attenuator, mastering the key of optical communication

Fiber Optic Attenuator is an optical passive device used to reduce the intensity of optical signals. It is widely used in optical fiber communication systems, optical fiber testing equipment and other fields.

Attenuation: It measures the degree to which the optical signal intensity is weakened by the optical fiber attenuator. The unit is decibel (dB). It is the main performance indicator of the attenuator and determines its ability to adjust the optical signal intensity in the system.
Attenuation accuracy: It refers to the deviation between the actual attenuation and the nominal attenuation. The higher the accuracy, the more stable and reliable the performance of the attenuator, and the more accurate the control of the optical signal intensity.
Return loss: It indicates the energy of the optical signal reflected back to the input end in the attenuator. The higher the return loss, the smaller the impact of the reflected light on the system, which can effectively reduce the interference of the reflected light on the optical signal and improve the stability of the system.
Working bandwidth: It refers to the wavelength range of the optical signal in which the attenuator can work normally and maintain the specified attenuation performance. Different types of optical fiber attenuators are suitable for different working wavelengths. For example, single-mode optical fiber attenuators are usually suitable for wavelengths such as 1310nm and 1550nm, and multi-mode optical fiber attenuators are suitable for wavelengths such as 850nm and 1300nm.

Great customer service

This fiber optic patch cable works really well! It works really well and I'm happy with the performance, you really take care of my products and I will be ordering another item again soon!

Cheyne

Great customer service

I really like these cables. All of my fiber optic ports are strung with these cables. They are affordable, easy to use, and work just as well as more expensive cables.
