In this paper

the shortage of pipeline resource caused by the development of communications business has been reported. The micro-trenching technology with microduct and microcable consisted of pavement grooving process and air-blowing process has been introduced and analyzed. This technology will use thick walled flatduct or direct buried microducts and microcable. Compared with the traditional communications cable laying technology

the micro-trenching technology could provide a high efficiency construction speed with low cost and high pipeline utilization. Meantime

the traffic obstruction

environmental pollution and destruction of the existing pipelines or road facilities is much less with micro-trenching mode. Communications operators in Europe

America

Southeast Asia and other regions have applied this technology in the metro and FTTH construction and achieved the launching of their network services quickly and efficiently.
