Communication optical cable manufacturers introduce the method of identifying the advantages and disadvantages of optical cables: fiber paste: fiber paste in outdoor cables can prevent the fiber from oxidizing. Because water vapor enters the tide, there is very little fiber paste used in low-quality fiber, which seriously affects the life of the fiber. Aramid: Also known as Kevlar, it is a high-strength chemical fiber. It is currently used most in the military industry. Military helmets and bulletproof vests are produced from this material. At present, only DuPont and Akzo in the Netherlands can produce, and the price is about 300,000 tons. Indoor fiber optic cables and power overhead optical cables (ADSS) both use aramid yarn as a reinforcing member. Due to the higher cost of aramid, inferior indoor fiber optic cables generally have a thin outer diameter. This can save costs by reducing a few strands of aramid. The fiber-optic cable is easily broken when it passes through the tube. ADSS optical cable is based on the span of the site and the wind speed per second to determine the number of aramid used in the optical cable. It must be carefully checked and confirmed before construction.
Communication optical cable manufacturers introduce the method of identifying the advantages and disadvantages of optical cables: Strengthening the steel wire: The steel wire of the outdoor optical cable of the regular optical cable manufacturer is phosphated and the surface is gray. Such steel wire does not increase hydrogen loss, rust, and high strength. Inferior optical cables are generally replaced by thin iron or aluminum wires. The identification method is easy-the appearance is white, and it can be bent freely when pinched in the hand. Optical fiber cables produced with such steel wires have large hydrogen losses and long periods of time, and the two ends of the fiber optic box will rust and break. Steel armor: Regular production enterprises use double-sided brushed rust-proof coating for longitudinal banding steel strips. Inferior optical cables use ordinary iron sheets, and usually only one side has been rust-proofed.
Communication optical cable manufacturers introduce the types of optical fibers: optical fibers are divided into indoor optical fibers, outdoor optical fibers, branch optical fibers, and distribution optical fibers according to different applications. According to the laying method: self-supporting overhead optical fiber, pipeline optical fiber, armored buried optical fiber and submarine optical fiber. Divided by fiber structure: bundled tube fiber, layer twisted fiber, skeletal fiber, clasp fiber, ribbon fiber, non-metal fiber and branchable fiber. Divided by purpose: long-distance communication optical fiber, short-distance outdoor optical fiber, mixed optical fiber and building internal optical fiber; optical fiber can be divided into single-mode and multi-mode according to the transmission mode, and single-mode fiber is generally used for monitoring.
