Single Mode fiber optic cable has a small diametral core that allows only one mode of light to propagate. Because of this, the number of light reflections created as the light passes through the core decreases, lowering attenuation and creating the ability for the signal to travel further. This application is typically used in long distance, higher bandwidth runs by Telcos, CATV companies, and Colleges and Universities.
Tele-Optics, Inc. built its organization from the quality splicing, inspecting, and testing of long haul outdoor fiber. Today, we have been able to refine our fiber solution into campus Fiber Optic Cabling wide connectivity (such as universities, elementary and secondary schools, manufacturing facilities) as well as data closet connectivity creating a fast and efficient network solution.
Pulling Strength: Some cable is simply laid into cable trays or ditches, so pull strength is not too important. But other cable may be pulled thorough 2-5 km or more of conduit. Even with lots of cable lubricant, pulling tension can be high. Most cables get their strength from an aramid fiber (Kevlar is the duPont trade name), a unique polymer thread that is very strong but does not stretch - so pulling on it will not stress the other components in the cable. The simplest simplex cable has a pull strength of 100-200 pounds, while outside plant cable may have a specification of over 800 pounds.
Another good reason for using fiber is that the light inside of the fiber degrades much slower than an electrical signal on a copper connection. So we can really plug in devices that are kilometers apart and we're still able to send that data because we're using fiber to be able to connect across those long geographic distances. And since we're not using any type of radio frequency or electrical signal on the cable- we're simply using light to extend it across- we don't get any type of common electrical interference.
