Connector SC Epoxy Polish APC UPC Patch Cord Single Mode Fiber Optic

Overview SC connector was developed by the laboratories at Nippon Telegraph amp;Telephone(NTT) in 1980s, hitting the market strongly after the advent of ceramic ferrules as the first connector.SC stands for “square connector” or “subscriber connector”, which is a push-on, pull-off connector with a locking tab.It has a push-pull coupling end face with a spring loaded ceramic ferrule by which SC connector can provide for accurate alignment. Commonly, it can be used with SingleMode amp;MultiMode fiber optic cables with low cost, simplicity amp;durability. Due to its excellent performance, it dominated fiber optics for over a decade amp; still plays an important part now. The fiber ferrule–In the heart of SC connector, there is a long cylindrical 2.5mm diameter ferrule which is made of ceramic or metal. The ferrule has a hole about 124~127um diameter in its center, so that the stripped bare fiber can be inserted through it. The end of the fiber is at the end of the ferrule, where it typically is polished smooth. The connector sub-assembly body–The ferrule is then assembled in the SC sub-assembly body. The end of the ferrule protrudes out of the sub-assembly body to mate with another SC connector inside a mating sleeve (also called adapter or coupler). SC Connector Types According to the polish style, SC connector can be divided into PC(Physical Contact), UPC(Ultra Physical Contact) amp; APC(Angled Physical Contact). SC APC connector–It is angled at an industry-standard 8°. As a result, any light that is redirected back towards the source is actually reflected out into the fiber cladding, again by virtue of the 8° angled end-face. That is why its back reflection is the lowest among the 3 types. APC connector is only available in single-mode amp; the color of it is green Connector Parts: Dust Cap, Outer Housing, Inner Frame, Ferrule Assembly, Spring, Stopper, Crimp Sets, Ring, Boot Insertion Loss≤0.25dB Return Loss≥60dB(APC) Durability≥1000times Cable Diameter 2 or 3mm
