Fiber Optic Cables - Research Paper Example This method uses devices such as visual fault located or fiber optic tracer to analyze broken connections within the fiber cables. The methodology involves a ray of light that is emitted from one end of the fiber cable from one of these mentioned devices. If the light signal is visible at the other end of the fiber, it concludes that the particular fiber is not broken ("Fiber Optics - Testing "). However, if the cable fails to show the ray of light from the other end, it concludes that the particular cable is broken or damaged from somewhere. The insertion loss method includes a laser that can reflect faults in a fiber cable. The laser is red in color and displays damaged area of the cables. Moreover, the method combines with the Optical Time Domain reflectometer that is used to measure lengths of fiber cables, to identify connection losses, identify fiber defects, and most importantly splice losses from the fiber. The functionality of OTDR involves a transmission of light from one e nd of the fiber cable. The light travels along the path and identify any possible anomalies. If the light encounters a dead end, a defect, or a cut in fiber cable, it reflects back measuring the distance of that particular fault. The OTDR illustrate graphs and traces on the screen incorporated on the device. The connection losses are calculated from the amount of light that is reflected from that particular area of the fiber cable ("Fibre Optic Cable Testing ").

Moreover, the devices powered by OTDR have provided high accuracy measurements in terms of fiber optic characteristics. The devices are portable and can be used effectively in the field. As a result, the installed fiber optics are determined efficiently according to system specifications. OTDR also provides benefits in terms of robust data transfer and correcting faults in a timely manner (DeMeis 161). Furthermore, the most widely used method for measuring l osses is the Optical Continuous-Wave Reflectometry (OCRW). The functionality of this method involves a transmission of a continuous wavelength via an interface, connector or a device that needs to be tested so that the losses can be calculated in a straight line. The light source that is emitted in this method is calibrated along with the utilization of detector-optimized optical power meter, the return loss calculations can be achieved with pinpoint accuracy (Brown 48). Testing Devices The current applications powered by web 2.0 are rich video, voice, flash, Ajax etc. in order to provide high bandwidth capacity Dense Wavelength Division Multiplexing networks are crucial. Network dictionary provides a most comprehensive definition of this new technology as â€Å"Dense
