>>It all looks like a possibility but whatever they are doing, they don't speak with the clarity and freedom of speech that comes with a good [protectable] patent position.<<
With the noted inclusion [protectable] above, agreed.
>>If they need to do that to send a signal down a fiber, then they would need to do something similar with the electrons that they are sending over an electrical wire from the mixer to the electro-optical modulator!<<
This begins to depart from a purely theoretical discussion and embarks on real world engineering, if I am interpreting your point correctly. If you think differently, please advise.
It begins to address those situations which any new transmission tech will face. We may begin to see here some of the compromising situations which I mentioned in an earlier post. Assuming I'm correct, it may be beneficial to agree on some ground rules, based on some pre-existing crieteria into which this model will undoubtedly need to backwards fit.
I'm proposing that we define some of the existing constructs which address the formation of higher order transmission streams in today's global telecommunications transmission systems.
Assume that the compactified stream in the SR model is of a very high order, in the several hundred gigabit range. Say, 200 Gb/s to form a base of discussion. Lower order (traffic- and protocol overhead-bearing) tributaries that feed it may be Sonetized, i.e., they may exist in the state of Synchronous Optical Network, or SONET.
Sonet is made up of optical carrier channels, also called tributaries, designated as OC-n, and lower wireline speeds. These are the conventions used to characterize Sonet, one of the popular forms of transport enveloping techniques in universal use. (Although this may not be the optimum example for an SR stream over the longer term.)
There are many other line protocol candidates that can be discussed, some which are still emerging over & under silica directly, but let's stick with the prevalent one for now, which is Sonet (and its near-equivalent, the European SDH), today's Layer One staple throughout the industry.
Tutorial Sidebar [Not intended directly for you, George, since I have a sense you already have this covered, but as a general consideration for anyone not familiar with North American tansmission standards.]
In order to achieve the highest singularly packaged Sonet rate of OC-192 (at the present time), there are various mux stages that exist beneath it, starting with the "Digital Signal at Level Zero," or,
DS-0 at 64 kb/s, then
DS1 or T1 at 1.544 Mb/s,
DS3 or T3 at 44.736 Mb/s,
From this point, the optical carrier structure takes over,
OC-3 at 155 Mb/s,
OC-12 at 622 Mb/s
OC-48 at 2.5 Gb/s
OC-192 at 10 Gb/s
All of the higher rates (above T3) are rounded, and there are many other intermediate stages, many of which are termed "virtual," but this provides us with the major break point denominations, and sufficient information for discussing legacy conditions, when the time is right. It may be helpful during future discussion if you bookmark this page now.
Four OC-48s combine to produce the OC-192, or in electronics this may be achieved through straight time division multiplexing of OC-ns of various denominations. In any event, the OC-192 equates to roughly 10 Gb/s.
In order to arrive at the 200 Gb/s rate, 20 OC-192s would need to be aggregated onto a single fiber at some point. Not only a single fiber, but in the case of SR, according to their claims, the 20 OC-192s would combine onto a single wavelength.End Sidebar.
We could proceed using this as an hypothetical model for use in examination and debate. I'd like to point out that thread discussion can become cluttered and disjointed very quickly with divergent lines of thinking, if we begin to go directly to engineering solving, while at the same time untangling the patent's claims at a theoretical level, as our colleague AHhaha is about to pursue. This is just an observation in lieu of conversational traffic controls, or an elected thread moderator.
edit: I just noticed that AHhaha's already posted the first installment of the patent for discussion. I should make it a point to read all messages prior to posting. Let the analysis begin. |
