Background to the study

The use of Fiber Optic cable in telecommunication has become

common in recent time due to the increasing demands of

bandwidth by the ever increasing subscribers

Fiber optic cables infrastructure requires maximum attention

and protection from damage

This research is focused on developing a more secured

underground fiber installation using a link sensor technology.

Problem statement

Numerous Fiber Cuts experienced by

Telecommunication Companies


EDUCATION

Objective of the Study

Design and simulation of a link sensor

mechanism which has the intelligence of

detecting and showing exact location of fiber

optic cable attack and disturbance.

EDUCATION

Significance of the study

The outcome of this study will help minimize

fiber cuts by the deployment of the link sensor.

With the link sensor in place, location of faults

will be easily identified for restoration work to be

done very fast.

The amount of trenching done by the

maintenance team in detecting the exact

location of the fault would be minimized.

Literature Review

Sample 1: The use of Sample 2: Prevention of fiber

warning tape to provide cuts using bricks (Uranium

Literature Review (cont’d)

Sample 3: Using Future Fiber Technology Secure Link

to prevent Fiber cuts (Future fiber technologies Pty. Ltd.

2009)

Limitations and Recommendation

From the works reviewed so far, we have concluded

to improve upon the use of the secure link sensor to

prevent fiber cuts.

We would therefore recommend the use a

piezoelectric cable installed on the warning tape at

1/4 depth of trench from bottom to prevent fiber cuts.

An emergency cable would also be installed at a

depth of 3/4 of trench before final backfilling is done

to prevent fiber cuts.

Analysis and Conclusion

As shown from the results the emergency message

displayed indicates that the emergency sensor wire

has been cut

The message shows a disturbance at A, B and C

indicating that the piezo sensor is sensing vibrations

which could pose a danger to the safety of the fiber

optic cable.

From the simulation the link sensor was able to detect

disturbances on the fiber network infrastructure.

1.8 Recommendation

We recommend that the sensor mechanism

should be improved upon to cover more

distances on the installed fiber network.

The link sensor should be integrated with the

installed fiber equipment.
