Do you know what is the fiber attenuator used for? As we know, the source of the single mode fiber is laser, the power of which is extremely strong. Therefore we can use single mode fiber to achieve long distance transmission. But, if the transmission distance over single mode fiber is too short, too much light may overload a fiber optic receiver, which may cause serious high bit error rates. How to solve this?
With the advancement of DWDM technology, as well as the potential to flexibly upgrade the reconfigurable optical add-drop multiplexer (ROADM), the demand for optical attenuator is sure to soar, especially for optical variable attenuator.
