Abstract: An optical fiber connector assembly (70) includes a duplex clip (30) having two cavities (32) and two standard SC type connectors (10) side-by-side received therein wherein one connector (10) inter-mates with an optical emitter and the other connector inter-mates with an optical detector. A loop-back optical fiber (20) is generally positioned in the rear exterior of the duplex clip (30) with two distal ends of the fiber being respectively connected to the rear ends of the corresponding two connectors (10) inside such duplex clip. A back shield (40) fixedly encloses the duplex clip (30) from the back wherein such back shield (40) further includes a rearwardly projection hermetic portion whose shape conforms to the configuration of such loop-back fiber (20) for protection. Also, for protection, two caps (48) can be optionally respectively attached to the front portions of the connectors (10) extending forwardly from the clip (30).

Abstract: A clip (10) is composed of two halves (12). Each half (12) has a main plate (14) from which a left side wall (16) and a right side wall (18) extend vertically at two opposite side edges. Each side wall (16, 18) incorporates a corresponding auxiliary wall (26, 28), which is extending vertically from the main plate (14) approximate a central slot (20) in the main plate (14), to form a cavity (22, 24) therein. A rear wall (30) extending from the rear edge of the main plate vertically, has two generally semi-circular openings (32, 34) therein in alignment with such two cavities (22, 24), respectively. A stopper (36) is formed generally in alignment with the auxiliary wall (28) which is facing to the right wall (18). A catch (42) and a latch (38) are respectively on the right and the left walls (18, 16).
