  • Page 6: Introduction

    Introduction The FSU 995 FA is designed to be “the only single fiber splicer you’ll ever need. ” It handles all basic single fiber splicing procedures, as well as more complex tasks such as tapering, attenuator making and erbium splicing. At the heart of the splicer’s operations is the hot core alignment process, which individualizes the splicing procedure to fit your fiber type and climactic conditions in order to offer the lowest...

  • Page 12: Fiber Preparation

    Fiber preparation Slip on a heat-shrinkable sleeve Easily forgotten, yet so frustrating. Remember to always slip a heat-shrinkable sleeve onto one of the fibers at the begin- ning of fiber preparation. Strip the fiber First remove at least 50mm of secondary coating (true for both tight and loose tube secondary coating) with a stripper appropriate to the type of coating you have.
  • Page 13 Cleave the fiber Before cleaving the fiber, make sure the fiber is clean and properly prepared (See steps 1-3). Cleave the fibers using a high quality cleaving tool that offers a flat end-face at an angle of less than 1 from the perpen- dicular (less than 0.5 for small core fiber).
