A fiber pigtail is a single, short, usually tight-buffered, optical fiber that has an optical connector pre-installed on one end and a length of exposed fiber at the other end. The end of the pigtail is stripped and fusion spliced to a single fiber of a multi-fiber trunk. Splicing of pigtails to each fiber in the trunk "breaks out" the multi ...
ClearCurve is the end result of a Corning research project looking for products better tailored to the fiber to the home market. [6] Running since 1988 at their Sullivan Park research center in New York, Corning announced ClearCurve at a press event on 19 September 2007 and showed it publicly at the FTTH Conference later that month.

The splice cassette is removable in order to assemble fiber optics with a splice unit. The front panel can also be removed to splice the fibers to various connectors. Since modern splice cassettes already contain a splice tray, a splice holder, couplings and pigtails , the installation of the cables is facilitated.
Here one differentiates core and jacket centering. At core centering (usually single-mode fibers), the fiber cores are aligned. A possible core offset with respect to the jacket is corrected. In the jacket centering (usually in multimode fibers), the fibers are adjusted to each other by means of electronic image processing in front of the splice.
The Telecommunications Industry Association's TIA-598-C Optical Fiber Cable Color Coding is an American National Standard that provides all necessary information for color-coding optical fiber cables in a uniform manner.

Other than the method of alignment, all forms of optical fiber splicing, including non-mechanical fusion splicing, involve an essentially identical process of cleaving and testing. Good cleaving, by creating a flat surface for fibers to be aligned and connected on, reduces splice loss in all forms of optical fiber splicing.
Corning's Vascade® EX2500 fiber, a low loss single-mode fiber for telecommunications wavelengths, has a nominal attenuation of 0.148 dB/km at 1550 nm. [65] A 10 km length of such fiber transmits nearly 71% of optical energy at 1550 nm.
