Abstract

The invention discloses a rapid sequence of FC-SC, FC-SC-APC fiber. The rapid sequence is pressed tightly into an FC or SC shell (2) by a spring (3) through a spring connecting base (4); a tail shell (8) is arranged on the tail end of the spring connecting base (4) as an integration; a contact pin (1) is fixed in a contact base sleeve (5); the contact pin (1) is provided with a precise and tiny guide positioning hole (1-1) inside; the front end of the contact base sleeve (5) is provided with a carrying cavity (5-1) as a pressing device; the tail end of the contact base sleeve (5) is provided with a large conical cavity (5-3); a V-shaped block (9) and a gland (10) are arranged in the pressing device, the carrying cavity (5-1); a fastening screw (7) is connected with the tail end of the contact base sleeve (5) to form a locking cavity; and a bipyramid chuck (6) is arranged in the locking cavity. No jointing points of the rapid sequence achieve ultra-low insertion loss control; 8 degrees APC slope polishing significantly reduces the loss value in fiber jointing; and repeated recycling decreases the utilization cost.

Description

technical field [0001] The invention relates to a connection device, in particular to FC-SC and FC-SC-APC optical fiber fast connectors. Background technique [0002] At present, in the field of optical fiber docking of FTTH fiber-to-the-home and triple play projects, there are no corresponding products for the connectors used in FC-SC and FC-SC-APC fast connections, and the existing products cannot be simple, convenient and reliable. , Low-cost connection. Contents of the invention [0003] The purpose of the present invention is to: provide a kind of FC-SC, FC-SC-APC optical fiber fast connector, realize the ultra-low loss connection without discontinuous point when the optical fiber is quickly connected, simplify the complexity of the optical fiber construction project, and improve the success of the optical fiber cold connection rate, greatly reducing the return loss value, and can be recycled to reduce the cost of use. [0004] The technical solution of the present ...
