An apparatus for removing excessive adhesives from ferrules, includes a holding device (1, 2) for holding the end face of a ferrule (F) at a predetermined position; a string member (4) for adsorbing or absorbing the adhesives; and a drive unit (3) for driving the string member on or near the end face of the ferrule.

Apparatus for removing excessive adhesives from ferrules

An apparatus for inserting an optical cable into a ferrule which has a cable housing aperture and a fiber retention aperture connected to the cable housing aperture via a tapered section, which includes a cable holder (2) for holding an optical cable (1) from which a length of cable jacket is removed to expose an optical fiber (1B); a ferrule holder (5) for holding a ferrule (F) such that a cable housing aperture (F1) and a fiber retention aperture (F3) are aligned in an extension line of the optical cable; a guiding unit (4) disposed in front of the ferrule holder and having a pair of guiding members (41A, 41B) to form a guiding aperture (43) with a diameter slightly larger than that of the fiber retention aperture; the guiding members movable sideways so that the ferrule holder brings the ferrule close to the cable holder, thereby inserting the optical cable into the ferrule.

Apparatus for inserting optical cable into ferrule

An apparatus for attaching an optical cable to a ferrule (F) which has a front aperture (F1) for holding an optical cable and a rear aperture (F2) for retaining an optical fiber of the optical cable, which includes a support block (1); a vertical passage (2) extending downwardly from an upper face of the support block; a sealing member (3) disposed around the vertical passage for making an airtight seal when a rear section of the ferrule is set in the vertical passage; a lateral passage (4) extending laterally from a side of the support block and communicating with the vertical passage; and a suction unit (5) connected to the lateral passage to draw a quantity of adhesive from the front aperture to the rear aperture, forming a mass of adhesive.
