ADSS Fiber Optic Cable

ADSS Fiber Optic Cable

ADSS Fiber Optic Cable installation span more than 1000 meters, It could be installed on the same tower for high voltage power line, or used for telecom system lines spanning rivers and mountains.

ADSS is an alternative to OPGW and OPAC with lower installation cost. The cables are designed to be strong enough to allow lengths of up to 700 metres to be installed between support towers. ADSS cable is designed to be lightweight and small in diameter to reduce the load on tower structures due to cable weight, wind, and ice.

In the design of the cable, the internal glass optical fibers are supported with little or no strain, to maintain low optical loss throughout the life of the cable. The cable is jacketed to prevent moisture from degrading the fibers. The jacket also protects the polymer strength elements from the effect of solar ultraviolet light.

Using single-mode fibers and light wavelengths of either 1310 or 1550 nanometres, circuits up to 100 km long are possible without repeaters. A single cable can carry as many as 864 fibers.

1.Product Introduction of the ADSS Fiber Optic Cable
With high tensile strength, installation span reaches more than 1000 meters to the maximum. Free from metallic material, with good insulation performance. Special outer sheath with strong resistance against electric corrosion.It could be laid on the same tower for high voltage line of 200KV or higher. Aramid yarn reinforcement with strong resistance against shock and bullet. With light weight Convenient for installation and maintenace (unnecessary for power supply stop)
2.  Application Range of the ADSS Fiber Optic Cable: It could be installed on the same tower for high voltage power line, or used for telecom system lines spanning rivers and mountains.
3.  Mounting Ways of the ADSS Fiber Optic Cable:  for aerial mounting
4.  Application Temperature of the ADSS Fiber Optic Cable: -40 ~ +70℃Remarks: W- ideal value for cable used under worst wether condition(covering ice, wind, extreme temperature, etc.) considering actualcircumstances (drop, span,height difference, etc.); T- ideal value forcable used under common weather conditions (common covering ice,wind, extreme temperature, etc.) considering actual circumstances(drop, span, height difference,etc.)W,T value could be confirmed through discussion with customers.Application Temperature: 40 ~+70;Attenuation coefficient change at 1310nm and 1550nm remains no more than 0.05dB/km within the range.Electric & Environmental Performance Water Penetration Performance: water block for whole crosssection(tested in L-shaped water rough)
