The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) sheath.
Product description
● The center loose tube protects the coated fiber once
● The optical fiber is concentrated in the center of the cable, and the strength members are distributed on both sides of the cable sheath
Features
● Small outer diameter, light weight, convenient construction
● Stable fiber excess length control
● After the cable is formed, the additional attenuation of the fiber is close to zero, and the dispersion value does not change
● Excellent environmental performance
Applicable laying
● Aerial laying
● Wear tube/blowing in tube
● Buried/underground
Structure
● The central loose tube protects the primary coated optical fiber
● The optical fiber is concentrated in the center of the cable, and the reinforcements are distributed on both sides of the cable sheath
● Water blocking layer is provided between the steel belt and the cable core
● Double-sided plastic-coated corrugated steel belt -Polyethylene bonded outer sheath
● Double steel wire parallel reinforcement
Performance characteristics
● Excellent water blocking layer, with good anti-seepage ability
● The outer sheath of steel tape is bonded and metal reinforced, with excellent tension performance
● The central design of the beam tube minimizes the influence of the optical fiber on the anti-lateral force of the optical cable
Note: It can be designed in rows of non-metallic structures according to user requirements
Scope of application
● Long-distance communication, inter-office communication, more suitable for southern regions
