FAST-SC Connector This technical report demonstrates the reliability of the FAST-SC connector in meeting mechanical and environmental performance criteria. Testing was conducted on mm and sm varieties of the FAST-SC connector in Fujikura test labs in Japan. The connector is designed for 250um coated and 900um buffered fibers. Testing was conducted on the 900um variety. Any questions should be directed to AFL Telecommunications. Submitted by: Kevin T. Monroe Project Manager Optical Connectivity and Apparatus Division AFL Telecommunications Kevin.Monroe@afltele.com Address: 170 Ridgeview Center Duncan, SC 29334 December 1, 2005 1. Description: The FAST-SC is a pre-polished fiber-stub field installable connector
suitable for premise, LAN and Telco applications. The connector does not employ a special assembly tool, but incorporates its own preassembled wedge clip. This clip is disposable and is attached as a part of each connector. The FAST-SC connector utilizes a push-pull-wedge mechanism originally introduced in Fujikura s mechanical splice. This mechanism achieves clamping bot the bare fiber and fiber coating, enhancing strength against fiber twist.
