I'm not sure if much has been written. I used to work on Google Fiber. One day a customer complained that their Internet wasn't working. A technician was dispatched. The technician found a wasp's nest where the fiber entered the customer's house and the wasps had chewed right through the fiber. I suppose it was surprising because glass is not a particularly soft substance -- with the right tools, sure, you can cut it, but it was surprising that wasps could cut it.
