RE: Optical Fibres - Transmitting Data at the Speed of Light
Well, I should have mentioned those black cables being laid underground by mobile carriers. They are indeed optical fibres clad with thick black rubber insulators. Thank you for visiting my blog. Steem on.
Oh, now that explains a lot.
One more thing; your posts are not too long, rather they contain a lot of information and are always a good read.
Thank you
