Optical fiber connector assembly with loop-back structure

An optical fiber connector assembly comprising:

• two standard SC type connectors (10) juxtaposed with each other, each standard SC type connector (10) including a hollow outer housing (12) to receive therein an inner housing (14) which is adapted to be axially movable with regard to the outer housing (12);
• a tubular housing (15) fixedly received within a rear portion of the inner housing (14) and a ceramic ferrule (16) coaxially moveable in the tubular housing (15) wherein a front end (17) of the ferrule protrudes out of the inner housing (14) and the outer housing (12);
• a U-shaped bare optical fiber (20) connected between two ends of said two standard SC type connectors (10) to form a loop-back;
• a duplex clip (30) being composed of two half covers (31) each including a hook section (32) and an indent section (34) for fastening with each other;
• two cavities (36) being formed in the clip (30) for side by side receiving said two standard SC type connectors (10) therein wherein each cavity (36) conforms to the outer housing (12) of the standard SC type connector (10) so that said two standard SC type connectors (10) can be properly retained within the corresponding cavity (36) without axial or lateral movement;
• a hollow back shield (40) protectively attached to the clip (30) from the back, said shield (40) including a rectangular portion (42) and a pyramid-like portion (44) whereby the rectangular portion (42) defines a rectangular cavity (43) for substantially fully enclosing the clip (30) and the pyramid-like portion (44) defines a pyramid-like cavity (45) for reception of said U-shaped bare optical fiber (20) therein.
