This article describes a new type of ultra-high-density large-fiber mesh fiber ribbons sloted cable,and explores and determines its structural design and process manufacturing methods.The main performance test results show that:compared with the traditional sloted cable,this product has the advantages of high density per unit fiber-km,light weight of the cable,small structural size and good flexibility without reducing the performance index of the cable.The Ultra-high-density 1152-fiber mesh fiber ribbons sloted cable developed:the attenuation coefficient of the optical fiber in the cable,at a wavelength of 1550nm,the maximum value is less than 0.22dB/km,the average value is less than 0.20dB/km;the maximum outer diameter of the cable is 21.8mm;the net weight per unit length is 420kg/km;optical fiber density in the cable reaches 3.17 fibers/mm^(2).
