Fibre optic cables are an important part of everyday society, whether it’s for keeping the internet running, connecting telephones or data networking. When these cables fail us, it can put many daily operations on hold.

But how can you test these cables to ensure that they’re functioning at full capacity?

This is where optical time-domain reflectometer (OTDR) testing comes in. This method of testing fibre optic cables is essential for a healthy network, as it can help identify weak areas in our fibre optic network.

So today we’re going to cover why OTDR testing is so important and provide the insights you need for an effective fibre optic network.
