Being able to join optical fibers with low loss is important in fiber optic communication. This involves careful cutting of the fibers, precise alignment of the fiber cores, and the fusing of these aligned cores. Fusion splicing is common when a permanent connection is required. In this technique, an electric arc is used to melt the ends of the fibers together. A splice loss estimate is measured by the splicer, by directing light through the cladding on one side and measuring the light leaking from the cladding on the other side.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=&#8221;15px&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_single_image image=&#8221;65541&#8243; img_size=&#8221;full&#8221;][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text css=&#8221;.vc_custom_1611073119025{margin-bottom: 0px !important;}&#8221;]\n<h4>Medical Lasers<\/h4>\n<p>The <a href=\"\/product\/pld5k-ch-5-a-laser-diode-driver-chassis-mount\/\" target=\"_blank\" rel=\"noopener noreferrer\">PLD5K-CH<\/a> is used to control a surgical laser, while the <a href=\"\/product\/htc3000-3-0-amp-temperature-controller\/\" target=\"_blank\" rel=\"noopener noreferrer\">HTC3000<\/a> keeps the laser within the appropriate operating temperature.
