A kind of new installation equipment, fitting product of pre-stranded wire, is used in electric power and optical cable communication industries extensively, which has the short history in production, sales and uses in China, but the demand of market is increasing continuously and the market prospect is wide, a lot of enterprises has been already attracted to enter this field.

the working methods, the procedures, to which a special attention should be paid, and the working requirement in the constructing of the communication optical cable buried directly in permafrost regions of the plateau are described, including working organization, line choosing, cable laying and protecting, etc.

Aiming at the difficulty optical cable-maintaining, this paper issues an intelligent diagnosis system based on GIS and expert system.

Aimed at the difficulty of the optical cable-maintaining.
