Understanding Mining Fiber Optic Cable: Beginner Guide

Date: 2022-12-14 17:18:00

Mining fiber optic cable is suitable for coal, gold, iron, and other mines. It provides flame retardant and rodent resistance properties, a good solution for mines, especially for accident-prone land mines, to ensure smooth communication, and reduce losses when an accident happens. This article will discuss mining fiber optic cable. 
What is Mining Fiber Optic  Cable?
Mining fiber optic cable ( flame retardant fiber optic cable or fiber retardant fiber ) is a special fiber optic cable used in the mining industry. Furthermore , mining fiber optic cable not only inherits all the performances of fiber optic cable but also adds special performances such as flame-retardant and anti-rodent properties due to the special requirements of the mining industry. 
Mining fiber optic cable structure uses 250μm optical fiber into a loose tube made of high-modulus material, and the loose tube is filled with a waterproof compound. The center of the cable core is a metal reinforcing core, around which the loose tube (and filler rope) are twisted into a compact and round cable core, and the gaps in the cable core are filled with water-blocking fillers. Double-sided plastic-coated steel tape (PSP) is longitudinally wrapped to extrude a polyethylene (PE) inner sheath, and a PE outer sheath is extruded outside the inner sheath to form a cable.


Features and Benefits
● Good flame retardant , good mechanical and temperature performance
● The high-strength loose tube is hydrolysis resistant
● Double sheathes and single armor provide excellent crush resistance, waterproof
● Special tube filling compound ensure critical protection of fiber
● Flexibility, high security, water-blocking system
Mining fiber optic cable is used in coal mines, gold mines, iron mines,  tunnel shafts, roadways, duct, aerial and direct buried installations, long-distance communication, and inter-office communication.


Mining fiber optic cable provides good flame-retardant, good mechanical and temperature performance, waterproof performance ensuring the safety of underground mines and flexibility. Sun Telecom has over 30 years of experience in manufacturing and supplying mining fiber optic cable. So please feel free to contact us if you have any needs.
