      It gets even worse for REALLY high frequencies, because they create eddy currents in the copper that impede the penetration of current into the conductor, restricting the current to the outer part of the conductor (the "skin effect") and thus raising the effective resistance and exaggerating the frequency-selective attenuation.

      This selective attenuation and delay weakens the signal - more at high frequencies than at low. As the wire gets longer the signal gets weaker and competing noise pickup gets stronger, reducing the signal-to-noise ratio and thus the amount of signal that can be carried.

      But the selective attenuation and delay also distorts the waveform, creating "intersymbol interference" (stored charge from previous bits affecting the latest bit). This can be compensated for.

      Current technology using SERDESes (fast serial bit streams), with some compensation for the selective attenuation (both preemphasis at the transmitter and compensation at the receiver), can get 3 Gbps through about a yard of printed circuit, or several yards of wire. More advanced devices (using tricks like four-level encoding to get two bits per modulation perios and feedback from the receiver to the transmitter by a return path) can go faster and a bit farther. (A transciever using all four pair of a Cat-5e, as of last year, could get gigabit ethernet across 30 meters.)

      Frequency-domain techniques (like ADSL) can do still better. And coding schemes have been developed that get within 50% (turbo codes) or even 90%+ of the Shannon limit bit rate.

      But what IS the shannon limit bit rate: It depends on a LOT of things. The biggest are:
      - Length of the wire.
      - Thickness of the wire.
      - Quality of the dilectric around the wire.
      - Interference coupled into the wire (i.e. how many other wires are in that bundle, what signals they're carrying, {for twisted pair} how tight the twists are and how they vary from conductor to conductor), how hot the wire is, etc.

      You should be able to get gigabit rates to a box on your block with copper pair, with a small router there and fiber to the rest of the net. (This is "fiber to the curb".) For 10G or beyond you'll probably need CO-AX (ala cable TV) or fiber from the curb box as well - otherwise the curb boxes would need to be so close together that they get too costly - and you might as well have strung fiber from the one-per-neighborhood boxes.

      (Maybe they'll push it a little farther. But I wouldn't hold my breath. Remeber that, in the US at least, you've typically got Cat-3 to the "curb" box which serves no more than 100 homes. If you're going to spring the bux dig it up and string 5e or 6 you might as well string some fiber. Later that can easily be upgraded to Tbits and beyond by transciever changes at the ends.)

And it's certainly easy to imagine scenarios involving pulling video from one source while streaming a different video to a different source over the same set of wires that could even now cause a non-trivial amount of strain on a 100Mbps network.

      So, yeah, I agree that 100Mbps is sufficient for our current needs and uses; but I doubt that our needs and uses will have increased tenfold by the time Gigabit, or perhaps even 10Gbps, becomes affordable enough.

      At DC the current will be evenly distributed throughout a uniform conductor. When the current suddenly changes the change occurs on the surface first, and propagates inward. If it changes gradually - like at low audio rates for small conductors - this propagation time is essentially nonexistent in comparison, so the result is essentially the same as with DC - though there IS enough skin effect to make a difference even at 60 Hz in really long power transmission lines.

    WHERE'S THE ROAD TO THE 'LAST MILE'? PERHAPS IN THE PACKAGING

    By Jeff Karoub
    Small Times Staff Writer
    March 23, 2004 - Industry watchers predict 2004 will see progress in getting "fiber to the home" - telecom's long-sought solution to the problem of directly delivering high-quality and high-speed video, voice and data. But the rollout still moves at a glacial pace because of the high costs of deploying fiber-optic networks to individual homes and businesses.

    Two Danish firms hope to offer some price-busting help in a small package.

    NKT Integration AS in February announced it is integrating MEMS-based packaging technology from Hymite AS into a planar light circuit that encapsulates the optical devices necessary for sending and receiving data and video signals. Such a system potentially could be cheaper because it can be assembled automatically - as opposed to the current manual approach - and micromachining the protective caps makes them smaller and lets developers pack more parts within them.

    "That's why optical equipment is so expensive; there's a lot of manual labor in packaging optical devices," said Jorgen Hoeg, Hymite's business development director. "The hurdle has been the cost of ... the installation of fiber and the optical transceiver that sits in the home. With this approach, we help reduce the cost of that device because it's built automatically and it's smaller. And smaller means less expensive."

    Hoeg said the deal is a "design win," meaning NKT engineers are working with Hymite's technology but the firms have yet to sign a contract. Still, he said, such a purchase order is likely, and he expects that a system incorporating the technology could be ready for the market by the end of the year.

    That dovetails with developments on the fiber-to-the-home front. The three largest telecom providers - Verizon, SBC and BellSouth - agreed last year on a set of standards for residential fiber-optic networks. Still, cost estimates of rolling out such networks range from more than $1,000 to nearly $3,000 per home.

    New packaging techniques also could benefit the MEMS industry, which places the price of packaging at anywhere from 60 percent to 85 percent of the cost of developing a device. The challenge comes in integrating parts into a package that protects them from the environment, but the package must also allow for those parts to interact with the environment.

    Hoeg said Hymite's packages, which are micromachined out of silicon, serve as a cap over the device as it sits in a cavity on a silicon substrate. The electrical connections are on the silicon and signals come out through its backside, which allows for a surface-mountable package. The approach creates packages that are hermetic, meaning they are free of leaks, and thermally compatible with silicon. When a package made of ceramic gets hot, the ceramic and the device expand at different rates and create tensions.

    Hymite also announced in February that it jointly developed an optical leak detector with Germany's NanoFocus AG for the hermetic testing of thousands of devices at a time on a wafer. Simultaneous tests are common in the electrical industry, but most optical testing today is done one device at a time, Hoeg said, and it can be both expensive and inaccurate.

    Once the caps have been sealed in place, Hymite changes the pressure surrounding the package, so the walls bend inward, or deflect. Then, using optical techniques and equipment developed by NanoFocus, the company measures the deflection to determine the presence and size of leaks.

    The leak detection system is used at Hymite's production facility in Berlin, but Hoeg said the company intends to sell it to customers using the company's packaging techniques.

      Actually, what gives it its characteristic impedence is the stray inductance and capacatance. Increasing the twisting increases both, and thus lowers the impedence. But thickening the insulation, thus moving the wires apart, reduces it, as does changing to an insulation with a lower permittivity. Wire size changes without proportional chanes in spacing also affect the impedence.

      Net result is you can get the impedence you want with any given twist rate by adjusting the insulation appropriately.

      The important things about twist rates are:
      - Twist rates of each pair must be DIFFERENT from that of its neighbors (so crosstalk cancels out on the average).
      - Twisting must be uniform and regular.
      - Twists should be short compared to the wavelength of the signal (so that you don't get a bunch of uncanceled cross-coupling, especially at the ends of the parallel runs).
      So tighter twisting is needed for high-speed data than for audio.

      This is why it is important to make sure cable buildouts don't have kinks in them. The kink causes an impedence mismatch in the middle of the run, which causes signal reflections, which tend to piss off the receiver.

      Kinks bring the wire closer to its neighbor, and to further sections of itself, which lowers the impedence. A local discontinuity reflects some of the signal back toward the transmitter - not much problem by itself. But TWO (or more) of 'em produce a delayed echo - like a ghost on a TV screen - at the receiver and that DOES cause lots of trouble.

      Similar problems can happen in coax, but [....]

      Main problem with a kink in a coax - even after you do your best to straighten it out - is that the center conductor ends up much closer to the outer shield, creating a BIG local mismatch.

      The connectors are probably the biggest cause of impedence mismatches.

      Especially since the designers of the connectors didn't, until maybe recently, really focus on keeping the impedence constant for the whole run through the connector. A sub-milimeter discontinuity wasn't a big deal at 100 MHz - but it's like a half-silvered mirror at 3 GHz.

      How about rigid coax or waveguide to the curb? :)

      Again, if you're going to dig from the house to the curb, why not just bury some fiber? That way you don't need to dig again for decades, rather than years.

    Has anyone ever achieved a sustained 1Gbps over copper? Usually it ends up between 0.4 and 0.7, if you've configured everything correctly, certainly not striaght out of the box.
