Indoor armored optical cable:
Single-core single-mode indoor armored optical cable (single armor)
There are single armor and double armor (indoor optical cable). The structure of the single-core indoor armored optical cable is: tight-packed optical fiber + aramid fiber (playing the role of tensile strength) + stainless steel hose (playing the role of compressive resistance, bending resistance, and anti-rat bite) + stainless steel braided wire (playing the role of torsion resistance) + Outer sheath (usually PVC, according to different functions, there are also flame-retardant PVC, LSZH, Teflon, silicone tube, etc.) single armor refers to the optical cable without stainless steel braided wire. Double armor refers to an optical cable with stainless steel hose and stainless steel braided wire. Advantages: high tensile strength, high compression resistance, anti-rat bite; can resist improper torsional bending damage; easy construction, save maintenance costs; adapt to various harsh environments and man-made damage. Disadvantages: The weight is heavier than ordinary optical cables. The price is higher than ordinary optical cables.
Single-core single-mode indoor armored optical cable (double armor)
Outdoor armored optical cable: There are light armor and heavy armor (outdoor optical cable). Light armor has steel and aluminum belts for reinforcement and protection against rodent bites. Heavy armor is wrapped with a circle of steel wire, which is generally used on riverbeds and seabeds. Generally, armored optical cables on the market are more expensive than non-armoured optical cables, and usually steel tapes and aluminum tapes are much cheaper than aramid fibers (aramid fibers are mainly used for special occasions). According to the metal armor, there are steel armor and aluminum armor according to the material. Usually in the form of bolts, a layer of metal armor is used to protect the fiber core, which can be bent naturally, has the advantages of high pressure resistance and strong tensile resistance, and can provide excellent cable protection and safety.
