ADSS all-dielectric self-supporting optical cable

ADSS all-dielectric self-supporting optical cable, the optical cable is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. An optical cable is a communication line in which a certain number of optical fibers form a cable core according to a certain form, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. That is: a cable formed by an optical fiber (optical transmission carrier) undergoing necessary processes.

Special Purpose Optical Cable

ribbon cable

An optical cable that is processed with multiple single optical fibers through coloring, stacking into ribbons, and secondary sheathing of optical fiber ribbons. There are two types of optical fibers, namely, encapsulated type and edge-bonded type. The former can withstand lateral pressure, and the latter is thinner. There can be 4, 8, 12 or 16 fibers in each ribbon. The in-band optical fiber spacing is 0.28mm (for 4, 8) and 0.3mm (for 12 and 16), neatly arranged, and there is flatness in the vertical direction, that is, the deviation requirement, not greater than 30, 40, 50um (according to the in-band Depending on the number of fibers), in order to facilitate cluster (fusion) connection. The in-band optical fiber uses color spectrum in an orderly manner, which is conducive to correct identification during maintenance and connection. The optical fiber ribbon is small in size, which can increase the packing density of the optical fiber in the optical cable, and can form a large number of cores, such as 320 to 3456 cores. Applicable to the current fast-growing optical fiber access network.

All-Dielectric Self-Supporting Optical Cable

It is referred to as ADSS (=All Dielectric self-support) optical cable, in which the reinforcing element of tensile strength is not metal but aramid yarn and glass fiber reinforced plastic (FRP). It is mainly used in strong current occasions, such as electric power and railway communication systems; at the same time, it is used in large-span occasions such as crossing rivers or complex terrain. ADSS optical cable can be constructed without power failure, electric tracking resistance, and wide temperature range.

Ground Composite Optical Cable

Referred to as OPGW (= Optical Power Grounded Wave guide), also known as optical fiber overhead ground wire, the ground wire in the power transmission line contains an optical fiber unit for communication. This kind of optical cable achieves both, that is, the electrical and mechanical properties of the ground wire will not be damaged due to the configuration of the optical fiber, and the optical fiber unit should be properly protected from damage. There are several types such as lead skeleton type, stainless steel tube type and submarine optical cable type.

Submarine cable

Optical cables laid on the seabed are used in both shallow and deep seas. The characteristics of this optical cable; one is to withstand a large hydrostatic pressure (1 ton per 10m deep) and the drag force during the release process; the other is to prevent hydrogen from invading the optical fiber.
