At present, there are three main types of new cable laying methods at home and abroad: one is to blow micro-cables or optical fiber bundles and optical fiber units into pre-laid micro-tubes using air blowing installation technology; the second is to open on cement roads.

It defines a minimum leve e fiber optic cabling extends between buildings. Although the standard covers premises installations, many of the provisions included here ar SI/ NFPA 70, the National Electrical Code (NEC). It is the responsibility of users. Minimize mechanical pressure on the outer sheath at crossing points: (armoured) cables crossing each other generate points of high pressure, so it is important when laying in figure 8 loops it is done in a correct way. Hanging wire support overhead method, this method is simple and cheap, and is the most widely used in my country, but it takes time to add hooks and arrange. a method of laying an optical cablehas also been proposed in which a groove is provided in a paved road surface and the optical cable is laid in the. ion titled “01-SDMS-01, Rev 01” which shall be considered as an integra applicable for the equipment/material covered in this Distribution Material Standard Specification.
