On Tuesday, Ziply fiber installed an optical network terminal (ONT) ... which I will discuss in another email. Besides being wicked fast, the wallwart that powers the ONT draws only 5 watts.
If we have another ice storm and 8 day power outage like we had in January, I would like to power that O.N.T. and a 5 port gigabit switch (2 more watts) for a week or more. BTW, the neighborhood "hub" for the Ziply fiber is a "wavelength division multiplexer" - a glass marvel that splits a single bidirectional multiband fiber into separate bands for customers. The WDM uses no electrical power. A typical 200 watt UPS uses quite a lot of the battery power just to power internal circuitry, and has limited sealed-lead-acid battery capacity. I can imagine a 10 watt output "mini" UPS that uses a tray of external lithium iron phosphide batteries and runs for days, using far less power for internal operation. Do products like that exist? Where can I buy one? Keith L. -- Keith Lofstrom [email protected]
