Armored optical cables have important applications in telecommunications optical fiber long-distance lines and primary and secondary trunk line transmission.
However, the armored optical fiber that general network management usually comes into contact with is mostly used to connect two optical fiber network equipment inside the computer room building.
The length of such armored optical fiber is relatively short.
Often called armored jumpers.
The so-called armored optical fiber (optical cable) is to wrap a layer of protective "armor" on the outside of the optical fiber. It is mainly used to meet the customer's requirements for preventing rat bites and moisture.
Indoor armored optical cable: There are single armored and double armored cables (indoor optical cable).
The structure of the single-core indoor armored optical cable is: tight-packed optical fiber + aramid fiber (for tensile strength) + stainless steel hose (for compression resistance, bending resistance, and rodent bite resistance) + stainless steel braided wire (Plays the role of anti-torsion) + outer sheath (usually PVC is used, and depending on the function, there are also flame-retardant PVC, LSZH, Teflon, silicone tube, etc.) Single armor refers to optical cables that do not contain stainless steel braided wires.
Double armor refers to an optical cable containing stainless steel hose and stainless steel braided wire.
Advantages: high tensile strength, high compression resistance, anti-rat bites; resistant to improper torsion and bending damage; easy construction, saving maintenance costs; adaptable to various harsh environments and man-made damage.
Disadvantages: It is heavier than ordinary optical cables.
The price is higher than ordinary optical cable.
Outdoor armored optical cable: There are light armor and heavy armor (outdoor optical cable).
Light armor has steel strips and aluminum strips, which are used to strengthen and prevent rodent bites.
Heavy armor is a ring of steel wire wrapped around the outside, and is generally used on river beds and the seabed.
Generally armored optical cables on the market are more expensive than non-armored optical cables, and steel strips and aluminum strips are usually much cheaper than aramid (aramid is mainly used for special occasions).
