Fiber Optic Cable 2 Core

30+ years

Our factory was found in 1992, first start with coaxial cable which was one of the biggest manufacturers in lin'an city.In year of 2001 started focusing on the production of optical cables.

30+ countries

In year of 2008, set up international sales department and sale optical fiber cable to more than 30 countries and have 18 years` rich experience to export cables .

 How many common cable structures are there?
Answer: There are two types: stranded and skeleton.

What does the optical cable mainly consist of?
Answer: It mainly consists of: fiber core, optical grease, sheath material, PBT (polybutylene terephthalate), and other materials. 

What does the armor of the optical cable refer to?
Answer: It refers to the protective elements used in special-purpose optical cables (such as submarine optical cables, etc.) (usually steel wire or steel tape). The armor is attached to the inner sheath of the optical cable.

What material is used for the optical cable sheath?
Answer: The optical cable sheath or sheath is usually composed of polyethylene (PE) and polyvinyl chloride (PVC) materials, which serve to protect the cable core from external influences.

List the special optical cables used in the power system. Answer: There are mainly three types of special optical cables:
Ground wire composite optical cable (OPGW), with optical fibers placed within the steel-covered aluminum-conductor structure of an electrical line. The application of OPGW optical cable has achieved dual functions of ground wire and communication, effectively improving the utilization rate of power poles.
Twisted optical cable (GWWOP), when applied in existing transmission lines, this type of cable is wound or suspended along the ground wire. Self-supporting optical cable (ADSS), with strong tensile strength, can be directly hung between two power poles, with the maximum span reaching up to 1000 meters.

What are the types of application structures for OPGW optical cable? Answer: Mainly include: 1) Layered structure with plastic sheath and aluminum tube; 2) Centered plastic sheath + aluminum tube; 3) Aluminum framework structure; 4) Spiral aluminum tube structure; 5) Single-layer stainless steel tube structure (centered stainless steel tube structure, stainless steel tube layered structure); 6) Composite stainless steel tube structure (centered stainless steel tube structure, stainless steel tube layered structure).

What are the main components of the twisted wire materials outside the core of OPGW optical cable? Answer: Composed of AA wire (aluminum alloy wire) and AS wire material (aluminum-clad steel wire).

What technical conditions should be considered when selecting OPGW optical cable models?
Answer: 1) Nominal tensile strength (RTS) (kN) of OPGW optical cable; 2) Number of optical fiber cores (SM) of OPGW optical cable; 3) Short-circuit current (kA); 4) Short-circuit time (s); 5) Temperature range (℃).

How is the bending degree of the optical cable limited?
Answer: The bending radius of the optical cable should be no less than 20 times the outer diameter of the cable, and during construction (non-static state), it should be no less than 30 times the outer diameter of the cable.

What should be noted in ADSS optical cable projects?
Answer: There are three key technologies: optical cable mechanical design, determination of suspension points, and selection and installation of supporting hardware.
