This may be common knowledge to communication guys but today I learned something new.
A simple crude way to test the integrity of a fibre optic cable is to shine a light at one end of the installation, if it is a clear pathway with no break light will pass through the cable at the other end of the run. Pretty sweet! This was with a very average small torch on an 80m run. If you have the fit for purpose torch it can do the same for a 10km run.
