Re: [Swprograms] Fiber optics, bandwidth, and cloud computing (was: Re: OT: Future of Digital Radio)
That is indeed a good analogy, Joe.
I spend more of my time on market / technology trend analysis in the
IT / communications space nowadays than the Chemical industry. Our
consulting firm survived the dot-gone bubble of 2000 and the recession
of 2008-9 in pretty good shape. Thankfully we are working for clients
whose own business has held up well.

Each LASER carrier is separately modulated. The efficiency is obtained by staggering the LASER wavelengths to not overlap modulation sidebands just like AM radio stations are spaced to prevent sidebands from overlapping.
