Bob sells it, I just have to make it work. He has the harder job.
I was a telecommunications systems & switch troubleshooter for years, but now I teach new techs how to be good ones for the company.
Warning: Geek-speak ahead. Avert your eyes before they glaze over!
Although it's all about optical in the world of getting bits from A to Z, as of right now the light has gotta be
converted to electrons for us to do anything else with it (Like have it make sense to a human brain).
This will change as new fundamental componentry in the optical world gets developed, but it is harder to get real improvements to core optical tech than any of the salesfolks thought it would be.
SONET is a data transmission-framing standard for optical transmission, but all SONET signals are electrical up to the last point of being put onto the fiber for transmission.
WDM is the optical version of individual radio stations in the FM band. Multiple colors of light, each color carrying up to 129,000 phone conversations.
Amazing that this "one system per frequency" technique which has been around in radio for almost a
hundred years took this long to come to the optical world. Why? - Because the bandwidth needs were not there
until relatively recently. Right now, there is a bandwidth glut in the backbone systems,
the real chokepoint is the "final mile" connection from network to consumer, and there are
LOTS of companies trying to figure out a cost effective solution to that one.
Basically, a lot of issues that data has problems with are because the network was designed to carry human speech. Pesky things, those brains.
Geek-speak transmission ends, we now return to the real world of skiing.
