Could come in handy in place, where several optical networks are installed. A big hotel let's say - you could have the data network and the fire alarm network on different colors. Sure, not absolutely needed, but why not, if it's available. There are also for sure places, where multiple optical networks are coexisting - from different ISP let's say, where they install their own fiber optics. They could use colors there too, so it's immediately visible what belongs to who.
Y you no make fiber in Australia?
WE SHOULD INVEST HEAVILY ON HIGH SPEED INTERNET
is this YOFC brand?
Prysmian is different brand from YOFC
What's the point of colored fiber?

to distinguish fiber within a cable, as multiple fibers are inside most cables, and knowing which is which is critical (at each end of the cable),
the preform is made from a hollow glass tube?
the core deposition occurs inside a hollow (silica) glass tube, and then collapsed into a solid rod.
@@marcschneider4117 OK, I see. Actually, we produce and supply the hollow glass tube making machine, drilling from a solid rod. :)
