How can DATALIGHT be checked?

Prior to connecting the fibre to the access point and the switch : Use a pocket torch to light into the end of the fibre – if light can be seen on the other end of the fibre, the fibre functions flawlessly. As soon as the fibre has been connected to the access point and the switch, green LEDs on the components indicate that they function correctly. Additionally, there are level measuring devices to calibrate the route.
