Optical fiber cutting device

An optical fiber cutting device comprising:

• a cutting blade having a cutting edge;
• an optical fiber supporter configured to support an optical fiber perpendicularly to said cutting blade at a cutting position;
• a cutting blade holder detachably holding the cutting blade and configured to move in a rectilinear direction toward the cutting position sufficiently such that the cutting edge of the cutting blade moves through the optical fiber in the rectilinear direction;
• a speed reducing part configured to reduce a drive speed of a drive force for driving the cutting blade holder;
• and
• a drive force transmission part positioned to receive the drive force from the speed reduction part and configured to move the cutting blade holder toward the optical fiber.

An optical fiber cutting device comprising:

• a cutting blade;
• a cutting blade holder detachably holding the cutting blade and move in a rectilinear direction to a cutting potion sufficiently such that a cutting edge of the cutting blade moves through an optical fiber in the rectilinear direction;
• speed reducing means for reducing a drive speed of an external drive force;
• drive force transmitting means for transmitting a drive force from said speed reducing means to the cutting blade holder;
• and
• optical fiber supporting means for supporting the optical fiber perpendicularly to said cutting blade at the cutting position.
