re: optical loop photovoltaics, this could be the start of something big?
Dave, in my preceding message (73) OSI speaks about optical powering of residential end point devices through the conversion of light energy to electrical energy.
The point being, there would be no need for running a separate metallic conductor in order to ensure that lifeline power is supported, because powering the end point could be achieved over glass.
Earlier this year, I'd suggested the same thing. I would be not only a means of remedying the life line situation in the event of a power outage, but would also present a huge savings in construction costs if outside powering didn't have to be installed. That was back in January, on the old FCTF:
Message 12530346
In that message I stated:
"When will these folks come to realize that they can do it all with fiber? Think I'm kidding? Let's think about it.
Think about using a part of the optical spectrum over low loss fiber for the purpose of delivering a supply of low amounts of optical energy.
Think opto-electric conversion using photo-voltaic cells.
Think voltage doubling through multipliers stepping up these low voltages at the station up to nine volts, instead of halving and dividing higher voltages out of headends down to -48 at the field node.
Think about battery trickle-charging to the levels of critical need, during idle times and periods of normal use when telephones would be powered by the user instead of the line. Think about it.
I ask once again, think about it. Is this for real? Because if it is, it's just broken the back of the copperheads' and coaxialists' most convincing argumentS against FTTH, from the perspectives of both lifeline services and construction costs.
Because, now lifeline powering would be supported via photovoltaic conversion, and the costs associated with providing a parallel power strand along every residential and backbone fiber path simply goes away. A huge cost savings, in fact.
I ask again, is this for real? Comments and corrections are welcome.
