The North American and Japan optical cable market is passing the 15 years milestone of the commercial availability of completely dry

or ’gel-free’

optical cable for the outside plant. Dry optical cable got rapid development and widely application in North America and Japan market

because dry cable

compared with gel-fill cable

has fast access

environmental protection

better moisture proof performance characteristics. By 2016

in North American optical cable market

dry optical cable demand occupied more than99% of total demand. And most of the fiber optic cable in Japan is fully dry water-blocking structure. In China optical cable market

the dry cable just started. This paper mainly descripted the fully dry non-metallic cable GYFY-144 B1.3 design

manufacture

and the application cases in Jiangsu Telecom. And compare the dry cable with gel-fill cable on fiber splicing efficiency and splicing attenuation. According the field application

the time of fiber preparing for splicing of dry cable can save 60% when compared with the gel-fill type. The dry cable has more safety

more reliable and more environmentally friendly splicing due to no chemical solvent and no consumptions goods.
