Charles Kao: A pioneer in optical fiber communications.
by jim bell 14 Sep '19

14 Sep '19

https://en.wikipedia.org/wiki/Charles_K._Kao "In 1965,[44][47]b[›] Kao with Hockham concluded that the fundamental limitation for glass light attenuation is below 20 dB/km (decibels per kilometer, is a measure of the attenuation of a signal over a distance), which is a key threshold value for optical communications.[48] However, at the time of this determination, optical fibres commonly exhibited light loss as high as 1,000 dB/km and even more. This conclusion opened the intense race to find low-loss materials and suitable fibres for reaching such criteria.[citation needed] Kao, together with his new team (members including T. W. Davies, M. W. Jones, and C. R. Wright), pursued this goal by testing various materials. They precisely measured the attenuation of light with different wavelengths in glasses and other materials. During this period, Kao pointed out that the high purity of fused silica (SiO2) made it an ideal candidate for optical communication. Kao also stated that the impurity of glass material is the main cause for the dramatic decay of light transmission inside glass fibre, rather than fundamental physical effects such as scattering as many physicists thought at that time, and such impurity could be removed. This led to a worldwide study and production of high-purity glass fibres. When Kao first proposed that such glass fibre could be used for long-distance information transfer and could replace copper wires which were used for telecommunication during that era, his ideas were widely disbelieved; later people realized that Kao's ideas revolutionized the whole communication technology and industry.[50] He also played a leading role in the early stage of engineering and commercial realization of optical communication.[51] In spring 1966, Kao traveled to the U.S. but failed to interest Bell Labs, which was a competitor of STL in communication technology at that time.[52] He subsequently traveled to Japan and gained support.[52] Kao visited many glass and polymer factories, discussed with various people including engineers, scientists, businessmen about the techniques and improvement of glass fiber manufacture. In 1969, Kao with M. W. Jones measured the intrinsic loss of bulk-fused silica at 4 dB/km, which is the first evidence of ultra-transparent glass. Bell Labs started considering fibre optics seriously.[52][end of quote] Of course, neither Kao nor any of his industry recognized what I eventually did: that even after modern-purified fused-silica was produced, there were still a few more sources of impurity in that, and that included Si-29 and Ge-73 isotopes. I fully expect that when these 'spin'-containing isotopic sources are removed, the silica single-mode fiber loss will drop to 0.001 dB/kilometer, about 150x lower than it currently is. Jim Bell

Cypherpunks: Jim Bell meets Sumitomo Electric

Jim Bell meets Sumitomo Electric at Seattle. I am driving to Seattle today to meet executives from Sumitomo Electric. https://global-sei.com/ They are one of the major manufacturers of optical waveguides. (fiber optics). https://global-sei.com/products/optical-fiber/ Sumitomo Electric has the distinction of having achieved the world record for optical waveguide loss, currently about 0.1419 dB/kilometer at 1560 nanometers. (This is apparently a laboratory result, not production.) https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=8267035 It beats one of its biggest competitors, Corning https://www.corning.com/worldwide/en/products/communication-networks/produc… primarily because Sumitomo employs a pure-silica fiber core, with a fluorine-doped cladding, whereas Corning has long employed a pure-silica cladding, with the core doped with germanium. One of Sumitomo's fibers, Z+150 has a production loss of 0.152 dB/km One of Corning's fibers, has a specified loss of less than 0.17 dB/km at 1550 nanometers wavelength. (A production result, not laboratory.) Into this 30 year+ competition I come, like a veritable bull in the technical china-shop. I got the attention of Sumitomo by using LinkedIn to send about 100 of their employees on Monday (as well as a couple thousand others at Corning, YOFC, OFS, Prysmian, ZTT, Hengtong, Nokia, Fujikura, Furukawa, Futong, Fiberhome, Ciena, Huawei Marine, and SubCom) a statement: "Your company should be selling a silica single-mode optical waveguide with a loss of 0.001 dB/kilometer. You'll think that's impossible but I know how to do it.https://www.linkedin.com/pulse/optical-waveguide-0001-dbkm-loss-even-10x… (What I have not yet mentioned is my belief that rather than the usual silica-fiber transmission "sweet spot" being about 1500-1600 nanometers, useful transmission will likely occur from 600-2000+ nanometer wavelength. This will keep fiber transmitter and receiver manufacturers busy for years!) Well, THAT got Sumitomo's attention !!! What I proposed amounted to, in their industry, a leprechaun saddled on a unicorn, itself standing on the back of a winged-pig. Flying. Jim Bell

Re: "lossless" optical waveguide - loss floor in glass media

Isotopically pure materials have lower losses when used as conductors (of heat, light, whatever). So anyway, I'd assume that people involved in optic fiber manufacturing were and are aware of the phenomenom so it's hard to imagine that they never tried to take advantage of it. And indeed you posted some news a few hours ago showing that they did? I guess we'll have to wait and see if some company specifically tries 'your' idea... cheers

Cryptocurrency: Random Coin Reading
by grarpamp 12 Sep '19

https://github.com/globatio/wiki/wiki/Whitepaper A fast decentralized distributed ledger would be highly resilient while allowing the distributed consensus to support very fast transactions and new applications. Whereas, many projects either choose proof-of-work or proof-of-stack for consensus and thus display either slow processing or centralization, we propose a mechanism in which both techniques work together in order to find a trade off between decentralization and scalability. Initially, the native cryptocurrency is created in the mainchain through a very secure decentralized (but also slow and restricted) proof-of-work mining and then can be stacked to initiate or participate in a sidechain with very fast proof-of-stack mining. Sidechain miners collect sidechain transactions fees of the block they produce and need to behave honestly in order to be able to transfer the fees they collect and have a good return from the amount they have stacked. Mainchain miners collect mainchain transactions fees and mining reward while overseeing sidechains miners in order to be able to accept the transactions from a sidechain to the mainchain. https://bitcoinroyale.org/bitcoinroyale.pdf Bitcoin Royale: Peer-to-Peer No-Theft Electronic Gold Ian Duoteli Fleming ianduoteli(a)protonmail.com bitcoinroyale.github.io Satoshi Nakamoto’s original vision for Bitcoin was to create a peer-to-peer version of electronic cash. The majority of successful forks of the protocol try to improve on this vision further and provide a more scalable and efficient system for payments. We see Bitcoin’s greatest promise not as a medium of exchange but as a store of value - a better form of gold, not cash. We propose a set of modifications to the original protocol aimed at fulfilling this promise by creating the ultimate electronic store of value. By increasing Bitcoin’s effective transaction confirmation time of 10 minutes to 24 hours, we are able to tackle Bitcoin’s greatest flaw as a form of gold - susceptibility to theft. A system geared less towards paying for coffee and more towards holding one’s life savings with complete peace of mind, where every transaction is alerted on-chain for 144 blocks and can be canceled on emergency with a recovery key that was never used prior and hence invulnerable. The bootstrap of this system is not via hard fork but through a fairer mechanism of expedited mining, allowing the system to catch up to Bitcoin in a short period of time.
