Fiber optic cables are vulnerable to excessive tension, sharp bends, and friction, which can degrade performance—sometimes only noticeable after installation. Underground cables are pulled in conduit that is buried underground, usually 1-1. 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. Cable Pulling Operations Pull steadily without frequent starts or stops, keeping force below the cable's rated limit. Bend Control and Lubrication Use. Tesmec offers an integrated value chain with specialized solutions: underground utilities detection and mapping, trenching, vacuum, home connection, backfilling, and road surface finishing. Typical trench dimensions range from. 2 mm) and 8 in to 17 in deep (20. Trench components have superior chemical resistance, strength, low water absorption, and substantial freeze/thaw resistance.
