The production line needs to be modified for the dry ribbon tube manufacturing by air charging. It contains inflator

ribbon lubricating device

aramid fiber pay-off machine and tension splitting wheel. Due to the effect of the force on the corner optical fibers

the attenuation of optical fiber was out of specification. The problem has been solved by changing the excess length and size of dry ribbon tube

The optical properties

temperature properties and mechanical properties of the optical cable are guaranteed.
