This coaxial cable have its own losses.We can not send signal at long distance by using these coaxial cable.We need to use amplifiers to amplify the signal with 100 meter distance approximately.Also we need to use supply for these amplifiers.It is hard to manage these coaxial cable in the field also because of its thickness. This is expensive thing for MSO or Digital Headend.The solution is&nbsp;<strong>OFC For Cable TV<\/strong>.<\/p>\n\n\n\n<p>Thus we used Optical Fiber Technology is having lower thickness than coaxial cable. We do not have need to use amplifiers at short distances.So OFC made this complex technology very easy. Now a days MSO is using OFC to send the signal to LCOs. LCOs are having not so long distance to reach their signal to subscribers.So they are using RG 11 and RG6 cable or known as coaxial cable.But if a LCO wants to make their services good then he can also use this OFC for his local network.<\/p>\n\n\n\n<p>Many big LCOs are having their local fiber to send their signals more efficiently.It makes their life easy because there is less number of complaints in Optical Fiber Technology.For cable tv operators 4F fiber is sufficient for his local streets.

In Fusion splicing we use a machine which align the two ends of OFC and then these glass ends are fused or welded.The welding take place because some type of heat has given two ends of fiber. Thus fusion splicing is done.The losses for fusion is lower like 0.1 dB in comparison with Mechanical Splicing.<\/p>\n\n\n\n<h2 class=\"BWS wp-block-heading\">What Is OTDR Or Optical Time Domain Reflectometer<\/h2>\n\n\n\n<p>OTDR stands for Optical Time Domain Reflectometer.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"250\" height=\"250\" data-attachment-id=\"555\" data-permalink=\"https:\/\/headendinfo.com\/ofc-cable-tv-headend\/otdr-for-cable-tv-digital-headend\/\" data-orig-file=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/01\/otdr-for-cable-tv-digital-headend.jpg?fit=250%2C250&amp;ssl=1\" data-orig-size=\"250,250\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"otdr for cable tv digital headend\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/01\/otdr-for-cable-tv-digital-headend.jpg?fit=250%2C250&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/01\/otdr-for-cable-tv-digital-headend.jpg?fit=250%2C250&amp;ssl=1\" src=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/01\/otdr-for-cable-tv-digital-headend.jpg?resize=250%2C250\" alt=\"otdr for cable tv\" class=\"wp-image-555\" srcset=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/01\/otdr-for-cable-tv-digital-headend.jpg?w=250&amp;ssl=1 250w, https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/01\/otdr-for-cable-tv-digital-headend.jpg?resize=200%2C200&amp;ssl=1 200w, https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/01\/otdr-for-cable-tv-digital-headend.jpg?resize=65%2C65&amp;ssl=1 65w\" sizes=\"(max-width: 250px) 100vw, 250px\" data-recalc-dims=\"1\" \/><\/figure><\/div>\n\n\n\n<p>OTDR is a device which is used to trace the fault in fiber for cable tv.OTDR sends optical power in fiber and it let us know how long it sent the power, threw this we get the fiber cut.At that end we can go and splice the fiber cut.
