"It is absolutely frustrating and the events have been increasing in frequency," said Rob Meyer, the vice president of engineering at Spectrum.
California leads the nation in copper wire theft. More than 1,800 incidents in six month just last year.
ABC7's 7 On Your Side has told you about many people who lose phone and internet service. Often times, thieves cut the cables only to find its fiber-optic, not copper.
"It's literally glass in a tube," said Meyer. "When you look at it that way, there's no value."
But the loss to customers is huge. That's why Spectrum showed us how difficult and time consuming it is to repair these fiber lines.
A wire might appear small, but inside each one there are 432 fiber-optic strands serving thousands of homes, businesses, hospitals, law enforcement and more.
"If a customer goes down, they feel the pain," Meyer said. "We're talking about people working from home, studying from home, all the impacts of everything that goes on around that."
Most of the calls for repairs happen in the middle of the night, and it makes it a lot more difficult to do the job.
When fixing a piece of cable, the job is to splice together strands no bigger than a human hair. You can barely see it.
It took an ABC7 reporter several minutes just to do one strand, so imagine having to do that hundreds and thousands of times just to fix one cable. That's why cutting these wires is such a big issue.
"The public can help us by, if you see something, say something. These critical infrastructure attacks impact everybody," Meyer said.
Spectrum is offering up to a $25,000 reward for tips and information related to fiber cuts. The number to call is 833-404-8477.
