Cable with an excellent transmission
The cable is made of large diameter quartz glass fibers specially manufactured for
Sunlight transmission.
It carries the visible rays of sunlight with little attenuation.
A single cable consists of a bundle of 6 optical fibers with a core size of 1 mm φ,
each of which is connected to one lens, i.e. one cable transmits sunlight
collected by 6 lenses.
