Hi John — Frank's thread has always been open to differing views on technology. They're plentiful and global. Where technology intersects with society is important, but difficult to handle because the dialogue can veer off-course to political and social debates.

My comments were about societal reactions -- not yours. That is, there are technological issues with which different societies have varying degrees of difficulty. Examples would be privacy in the EU vs. privacy in the US. Global warming responses in Denmark compared those in the 'States. Telecom in Japan, S. Korea and Sweden vs telecom in the USA. And so on ...

In that context, what we think is non-influential. True, we may reflect one stream of thought vs. another, but there are no world leaders or constituencies waiting on words from SI. Plus, there's a world beyond US borders. SI (more often than not) speaks from a parochial American POV. In this changing world, the relative importance of that viewpoint is decreasing.

On the fraught subject of nuclear power -- and no other -- we agree. As you say. Thanks for the discussion.

Jim

Hi Jim,

re: “Usually, lasers can generate only one wavelength,” Arabzadeh explains.”
--

This is not accurate, or at best, it's a dated notion. The statement leaves one to wonder if the author actually meant "generate", or through some other filtering means "extracted" multiple wavelengths. In any case, WDM PONs have been using broadband light sources for over a decade, employing various wavelength slicing techniques.

Incidentally, Nortel <R.I.P.>, or one of its surviving components, which is mentioned in the RANOVUS material, was among the first to take this approach, IIRC.

Now, whether quantum dot technology is more recently the enabler of a new approach to multi-wavelength lasers, is something I'd have to look at more closely. Thanks for the homework assignment ;)

As to the basic premise concerning energy savings, while very likely true, my thinking is that this would be consistent with the per-unit energy consumption curve of most newly introduced ICT technologies. And if it's not, it probably wouldn't doesn't pass muster, thus relegating it to non-starter status."

Thanks, Frank — The article stimulated interest, but left the reader unsatisfied.

I'll research the question too. But on this subject, my work is an unguided missile. Far more likely that you will perceive whether there's anything of substance here. Should you find time to investigate (among your other priorities) any feedback will be appreciated.

... my thinking is that this would be consistent with the per-unit energy consumption curve of most newly introduced ICT technologies...

Odds are the reality doesn't match the headline. Probably I've been clickbaited :(

Jim,

As you my have inferred from my many posts on a closely related topic in the past, my position is that no individual component or network element alone has as much influence on a system's overall energy efficiency as the supporting infrastructure immediately surrounding it. See my Twitter profile page, whose pinned tweet contains a pointer to one of my posts to another forum of almost ten years ago:

@fcoluccio 1 Apr 2016 "It's not the type of wire you install that determines energy efficiency. It's the supporting architecture, Stupid!"

Thanks, Frank — For further research, that provides a cautionary framework.

Hi Jim,

As I mentioned offline, I encountered an abnormal condition here yesterday, manifest by one of my messages vanishing after a successful posting. It seems it was an isolated case. I'm wondering if anyone else here encountered this or anything similar?

--

Back to the magic of quantum dot technology, or, as Einstein dubbed quantum entanglement, spooky action, I've done further digging (by no means exhaustive) and can't find anything in the trades or literature corroborating the larger message behind the release: "Putting the Internet on an energy diet."

The more I think about this claim, the more unlikely it seems. Since this is something that directly touches on my own areas of interest, I'll do a more exhaustive search. and call the company sometime this week and ask for clarifications. One way or the other, I'll get back here with my finding.

'... I've done further digging (by no means exhaustive) and can't find anything in the trades or literature corroborating the larger message behind the release: "Putting the Internet on an energy diet." '

— Same here. That was what triggered my query to you. That fact must be weighed against the company's origins, genetics and bona fides.

'Since this is something that directly touches on my own areas of interest, I'll do a more exhaustive search. and call the company sometime this week and ask for clarifications. One way or the other, I'll get back here with my finding.'


— There'll be more discerning questions (and likelihood of answers) thru you than via muggles like me.

'The more I think about this claim, the more unlikely it seems.'

— Yes. Probably time and attention has been captured by marketing and hype. But, maybe not. Looking forward to your evaluation.

Jim

Mobile vendors used money losing Managed Services contracts to block changes in the network. Operators shed thousands of employees to them to concentrate on their business. Both were happy. It worked as long of the profits of selling SW and HW subsidized Managed Services. This is ending now.
