Field-assembled SC/UPC fiber optic connector FA-SC does not need polishing, and it is easy to be assembled at the installation site by workers. Unlike regular SC connectors, the FA-SC connector does not need additional tools to assemble. The splicing method of FA-SC is as simple as aligning the V-groove and sliding to Tie-up the fiber. The ¡°Sliding and V-groove tie-up¡± splicing method is possible to clamp both fiber and coated fiber. The clamping method provides better tensile for it than the field-mountable SC connector and fiber, and also avoid the twisted (tangled) situation. The Loss, Mechanical and Environmental tests on the assembled connectors show excellent results. The finished cables pass qualification tests to ensure the quality of our products subjected to severe mechanical and environmental conditions.
