Fiber optic cable can be run anywhere from 300 meters up to 80 kilometers (roughly 50 miles) depending on the cable type, transceiver used, and network standard. 2 meters (3-4 feet) deep to reduce the likelihood of accidentally being dug up. In extreme cold climates, cables may need to be buried at greater depths where there temperatures are colder and frost penetrates to. For longer distances, fiber-optic cables are typically installed by hanging them between poles (aerial), laying them on the seabed (submarine), or burying them in the ground (underground). Here are some general guidelines: 1. Indoor Installations For indoor fiber optic cables, the maximum pulling distance typically ranges from 100 to 200 meters.
