Here, the material of the conductor 31 is copper, and electrical characteristics are variable depending on the material, level and diameter of the copper.

The insulator 32 is made of polyethylene (PEP) and covers and protects the conductor 31 so as to maintain the shape of the conductor 31 and to satisfy the specifications of the conductor 31 in terms of electrical characteristics and flame retardancy / It is important to determine the

The jacket jacket 40

To protect the optical cable 10 and the UTP cable 30 from a physical shock or chemical danger from the outside,

The aramid yarn 20 and the UTP cable 30 are wrapped around each other with a circular cross section.

Polyvinyl chloride (PVC) or UV stabilized low smoke zero halogen (LSZH) is used as the coating material.

Meanwhile, the Ministry of Information and Communication recently revised the certification system for high - speed information and communication buildings in order to satisfy the speed and massification of information demand and to strengthen the competitiveness of the world.

The upgrading of existing class 1, 2, and 3 class apartments to high class, first class, second class, and third class has strengthened the level of elements required for each class. As follows.
