Broken Fiber Optics cable in the neighbourhood

Monday 8th of November, 2015, I was surprised to find a broken fiber optics cable in the neighbourhood. Fortunately, that did not affect internet connection to my home. I took a picture of the broken cable and inspected its contents.

The image shows that the fiber optics cable has been badly damaged. The outer jacket has been completely ripped off and the internal parts of the fiber optics cable are seen.

The black outer jacket is what encloses the whole fiber optics components. It is the protective outer coating of the cable, what usually people can see.

The red rod or string is called the rip cord. The rip cord is used to open the jacket.

After opening the jacket using the rip cord, the next layer seen is the kevlar. The kevlar is the white thread-like structures which is also a strength member in the jacket of fiber optic cable.

To the complete right of the image, there is a white tube, which looks fairly strong. The tube contains a very thin blue cable which contains the fiber. The strong tube is most probably the teflon tube .
I was surprised to see this tube slightly damaged. It may be possible that bats have damaged the cable since there are traces of bites in the teflon tube. The cable passes through a mango tree before reaching the next pole.

Inside the strong tube resides a blue cable. Unfortunately, this is not easily seen in the image above. I used a broken piece of the cable to look the contents inside the teflon tube.

Inside the tube there is the fiber optics unit in which the fibers are found. The fibers are very thin and flexible and yet they are responsible for large amount of data transfer.

Presentation by Emtel at the University of Mauritius

Earlier this year in April, an Emtel representative gave an interesting talk on Fiber Optics. The presentation was focussed on how fiber optics work and the various fiber optics cables used for connecting networks.
The Emtel representative had brought some cables used to deliver Fiber optics connection.

The thick orange cable is passed through underground channels to connect networks. It allows several Loose Tube Optical Fiber Cables to be inserted and has its water blockage component.

The yellow cable is used for fiber to desktop which extends FTTH network direct to the desktop.

The other coloured cables are split further so that the fibers are seen. The cables look like the cable in the first image inside the strong tube which was not easily seen. The fibers are very thin and flexible. This is the last component that is seen when any optical fiber cable is split into its different components.
