Abstract: A optical fiber connecting device includes a hollow main body, balls, a sleeve ring, and a dust-proof sleeve. An hollow insertion portion of the hollow main body has a receiving recess and ball holes. The balls are received in the ball holes. The sleeve ring is sleeved around the receiving recess and has through holes respectively aligned with the ball holes. Each balls partially protrudes from one of the through holes. The dust-proof sleeve is removably sleeved around the hollow inserting portion and has an inner groove. The balls is engaged with the inner groove to retain the dust-proof sleeve.

Abstract: A fiber optic connector includes a connecting unit having a plurality of positioning grooves and a cover unit having a plurality of positioning blocks. The cover unit is operable to rotate relative to the connecting unit between an engaged position, where the positioning blocks are respectively disposed in the of said positioning grooves and are respectively and at least partially aligned with shoulder surfaces in the positioning grooves such that the cover unit is unable to move axially and forwardly relative to the connecting unit, and a separated position, where the positioning blocks are respectively misaligned from the shoulder surfaces to allow the cover unit to move axially and forwardly relative to the connecting unit.

Abstract: A branch fiber optic cable assembly includes a main fiber optic cable and a plurality of stub cables. The main fiber optic cable has a plurality of branching sites which are spaced apart from each other along an axial direction of the main fiber optic cable. Each of the stub cables has a first end integrally connected to the main fiber optic cable at one of the branching sites, and a second end extending away from the main fiber optic cable. A method of making the branch fiber optic cable assembly is also disclosed.

Abstract: A coupling device includes a socket defining a through groove and a connecting seat connected to a rear end of the socket. The connecting seat has a casing portion defining a plugging space therein, a base wall portion disposed in the casing portion and defining a through hole in spatial communication with the through groove and the plugging space, two first connecting portions respectively disposed at two lateral sides of the through hole and extending forwardly from the base wall portion to the through groove, and two second connecting portions respectively disposed at the lateral sides and extending rearwardly from the base wall portion to the plugging space. The socket and the connecting seat are formed as one piece.

Abstract: A fiber optic pulling grip assembly includes a sleeve unit sleeving around a cable section of a fiber optic cable and a guiding unit. The sleeve unit includes a sleeve member, an insertion tube received in a receiving space extending along the sleeve member, and a blocking member connected to the sleeve member. The guiding unit includes a fixing ring disposed between an optical fiber section and a mesh of the fiber optic cable, a rear portion connected to the sleeve member to clamp a rear end of the mesh, a front portion defining a channel for passing of the optical fiber section and the mesh, a connecting member connected to the optical fiber section and a pulling member connected to the front portion to clamp a front end of the mesh.

Abstract: A power cable adaptor includes a casing that has a receiving space, a retaining sleeve disposed in the casing and conductive members disposed within the retaining sleeve. The conductive members respectively define conductive channels. A cap is detachably connected to the casing and covers the receiving space. A wire dispenser is detachably received in the receiving space. The cap has an opening communicating with the conductive channels through the receiving space. The wire dispenser has wire passages communicating with the conductive channels and the opening of the cap.

Abstract: An assembling jig for an optical-fiber connector includes two sleeve halves inter-connectible to form a sleeve body. Each of the sleeve halves includes a front half section, a rear half section extending rearwardly and longitudinally from the front half section, an abutment face extending longitudinally from the front half section to the rear half section, a strain relief sleeve holding groove opens at a front end face of the front half section and a cable passage groove opening at a rear end face of the rear half section. When the abutment faces abut with each other, the strain relief sleeve holding grooves cooperatively form a strain relief sleeve holding hole, and the cable passage grooves cooperatively form a cable passage hole.

Abstract: An optical fiber distribution box includes a base, a seat, an input tube and output tubes. The seat includes a standing wall, two protruding ribs and two holes. The standing wall is disposed behind and connected to the base and has a positioning hole formed therethrough along a front-to-rear direction. The protruding ribs rearwardly extend from the standing wall, are opposite along a left-to-right direction, and respectively formed with two through holes for extension of a binding belt. The holes extend through the standing wall and respectively through the protruding ribs and flank the positioning hole.
