For solving the problems of the technologies described above, the utility model provides a kind of novel optical fiber attenuator, comprises driving wheel, and described driving wheel one side arranges elastic cylinder, described driving wheel opposite side is disposed with engaged wheel and optical fiber fixed bar, the stranded optical fiber that arranges on described optical fiber fixed bar outer rim; Described driving wheel one side sets gradually rotary sleeve, driving shaft and drive motor, and described driving shaft connects drive motor and selects shell, and described rotary sleeve is connected with driving wheel.
As further improvement of the utility model, described driving shaft runs through rotary sleeve and is connected on elastic cylinder.
As further improvement of the utility model, described driving shaft external diameter is 10 ~ 20mm.
As further improvement of the utility model, described rotary sleeve adopts card and links with driving wheel, and described rotary sleeve external diameter is less than the driving wheel external diameter.
As further improvement of the utility model, described elastic cylinder external diameter is 20 ~ 30mm.
As further improvement of the utility model, described driving wheel and engaged wheel are for movingly.
As further improvement of the utility model, described engaged wheel external diameter is greater than the driving wheel external diameter.
As further improvement of the utility model, between described driving shaft and rotary sleeve, adopt bearing to be connected.
The utility model compared with prior art has following beneficial effect:
1. the utility model rational in infrastructure simple, stability is high, equipment cost is low, stable;
2. the utility model can make optical fiber reach in loss-free situation to complete the decay effect, the impurity that can also reduce rotary course Elastic cylinder simultaneously overstocks.
