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

A machine for mounting a ferrule on an optical fiber cable which includes a plurality of function units (11-17) arranged in a line, including a control and display unit (11) and an inserting unit (16) for inserting an optical fiber into a ferrule which has been injected with an adhesive; a plurality of pellets (21-29) for holding a ferrule and an optical fiber cable and traveling along the function units for circulation; a memory divided into a plurality of areas; a presence detector (13) for feeding the memory in a corresponding area with a failure signal if a ferrule or an optical fiber cable is not present on a pellet (23); an adhesive detector (15) for feeding the memory in a corresponding area with a failure signal if a predetermined amount of adhesive has not been injected into a ferrule; a projection detector (17) for feeding the memory in a corresponding area with a failure signal if a predetermined length of optical fiber does not project from a ferrule after the optical fiber has been inserted through the ferrule such that all of said failure signals are displayed when the pallet returns to the control and display unit.

Apparatus for mounting optical fiber in ferrule

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.

Method and apparatus for attaching ferrule to optical cable

A multiple optical fiber connector terminal includes a sleeve (6); a plurality of pins (7) disposed within the sleeve to form a plurality of receiving apertures (9); a plurality of filler rods (8) disposed between the sleeve and the pins; and a plurality of optical fibers (10) inserted into and bonded to the receiving apertures.

Multiple optical fiber connector terminal and method of making same

An optical fiber connector terminal includes a sleeve (6); a plurality of pins (7) disposed equidistance from a center within the sleeve to form a receiving aperture (9); a plurality of filler rods (8) disposed between the sleeve and the pins; and an optical fiber (10) inserted into and bonded to the receiving aperture.
