Band -like optical cable advantage

Discussion on the special use of optical cable

Everyone who touches optical cables may not have access to those special-purpose optical cables, or only a part of them. Let us discuss the special uses of those special optical cables.


Optical cables are mainly composed of optical fibers (glass filaments as thin as hair), plastic protective sleeves and plastic sheaths. Optical fiber cable is a kind of communication line in which a certain number of optical fibers form a cable core according to a certain method, which 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) through a certain process.


ZR Cable

Special optical cables have special uses, such as:

ribbon cable

An optical fiber cable that is processed into a unit of a plurality of single optical fibers through coloring, stacking into ribbons and secondary sheathing of optical fiber ribbons. There are two types of optical fibers, namely the encapsulated type and the edge-bonded type, the former can withstand lateral pressure, and the latter has a thinner thickness. Each band can have 4, 8, 12 or 16 fibers. The fiber spacing in the band is 0.28mm (for 4, 8) and 0.3mm (for 12 and 16), neatly arranged, with flatness in the vertical direction, that is, the deviation requirement, which should not be greater than 30, 40, 50um (depending on the in-band (depending on the number of optical fibers) to facilitate cluster (fusion) splicing.


The in-band optical fiber uses the chromatogram in an orderly manner, which is convenient for identification during maintenance and connection. The optical fiber ribbon is small in size, which can improve the packing density of optical fibers in the optical cable, and can form a large number of cores, such as 320 to 3456 cores. It is suitable for the current rapidly developing optical fiber access network.


All-dielectric self-supporting cable

Abbreviated as ADSS (=AllDielectricself-support) optical cable, the reinforcing element for tension resistance is not metal but aramid yarn and glass fiber reinforced plastic (FRP). Mainly used in strong electric occasions, such as electric power and railway communication systems; at the same time, in large-span occasions such as crossing rivers or complex terrain. ADSS fiber optic cable can be constructed without power failure, track resistance, and wide temperature range.


Ground wire composite optical cable

OPGW (=OpticalPowerGroundedWaveguide) for short, also known as optical fiber overhead ground wire, the ground wire in the power transmission line contains optical fiber units for communication. This kind of optical cable achieves both, that is, the electrical properties and mechanical properties of the ground wire are not damaged due to the installation of optical fibers, and the optical fiber units should also be properly protected from damage. There are lead frame type, stainless steel tube type and submarine optical cable type.


submarine cable

Optical cables laid on the seabed, with shallow and deep sea applications. The characteristics of this optical cable are: First, it can withstand a large hydrostatic pressure (the pressure is increased by 1 ton per 10m deep.) and the drag force during the casting process; the second is to prevent hydrogen from invading the fiber. It has been confirmed that hydrogen will cause the optical fiber to increase the attenuation; the third is the large span of the hop.


In submarine cables the fiber optic units are placed in the center of the cable and in a custom stainless steel tube. The tube is surrounded by high-strength arched steel wires. The steel wire layer is covered with copper pipe for remote supply, and it also prevents micro/macro bending when laying the optical cable. The outer sheath is then extruded. It may also be pinned to protect against sharps, including shark bites.


The introduction of the special application of optical cable ZR Cable is finished for everyone. I hope the readers can get the knowledge they want.
