ADSS оптического кабеля

ADSSoptical cable Description: The accelerated development in telecommunications and the need for higher transmission rates, to provide other services, such as multimedia, internet and remote conferencing, among others, has made optical cables the prime transmission media. Hengtong High quality ADSS cables will provide excellent transmission performance and protection of the fibers in variety of field environments. Its loose type design and the materials used in its manufacture provide full cable protection from bad weather. These cable shall be used in the area with lighting risks Vicinities of power line plants aerial installation.
