Optical Cable for Route Shortage

Optical Cable

With the rapid development of metropolitan area networks and access networks, less and less urban duct and hole resources are available. The improvement of urban municipal construction management makes it harder and harder to acquire approval for excavation and installation of cable systems. However, the communication network structure is scattered geographically, thus the mass installation of optical cables is facing the conflict between high costs and low utilization. The aforesaid problems bring challenges to optical cable routing constructions, i.e., route selections and route shortage....

It is a kind of optical cable with small diameter, which can be laid by cutting a narrow trench on the road surface, burying the optical cable in it and then back filling it to the original road conditions. This optical cable consists of single-mode/multimode fibres, a loose tube, aramid yarns as the strength member, a steel tape armor and a PE sheath It is featured with light weight, good flexibility, easy installation, low costs and fast installation speed, etc. Features • Accurate process control ensuring good mechanical and temperature performances • The material of loose tubes with...

It is a kind of self-supporting optical cable for laying in storm sewers. Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a metallic central strength member to form a cable core. The core is filled with water blocking compound and armored with laminated aluminum tape . Then a PE inner sheath is extruded and aramid yarns are placed outside the inner sheath as the strength member, Finally, a PE outer sheath is extruded. Features • Accurate process control ensuring good mechanical...

Note: 1. Xn refers to fibre type. For details, see naming rules for optical cables of YOFC. 2. For color arrangement of fibres and loose tubes, seethe color sequence. 3. D is cable diameter. Yangtze Optical Fibre and Cable Joint Stock Limited Company

The bending insensitive optical fibres, Easy Band® Plus-Mini(200 pm), are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The loose tubes with smaller size are stranded to form sub-units. The composite structure is formed by stranding sub-units, armoring with laminated aluminum tape and then extruding a PE outer sheath. This structure allows the optical cable to exceed 216 fibres (in 18 units), which enhances installation density of fibres in ducts. Features • Accurate process control ensuring good mechanical and temperature performances •...

Note: TM is short term tensile strength, TL is long term tensile strength. • Standard length: 2,000m; other lengths are also available. Yangtze Optical Fibre and Cable Joint Stock Limited Company 035
