Why do you need a fiber identifier and what can it do for you?
If you have ever seen a telephone company technician working on the phone jump box outside your carmit house, you should have noticed a special handheld phone like instrument. The technician uses it to identify the incoming telephone wires by tapping onto the wires and listening for a tone. Once he finds the correct wire, he connects the wire into your house.
During fiber optic network installation, maintenance, or restoration, it is also often necessary to identify a specific fiber without disrupting live service. This battery powered instrument looks like a long handheld bar and is called fiber identifier or live fiber identifier.
