Intel Rolling Out 800Gbps Cables This Year 101

Posted by Unknown Lamer from the silicon-photonics-sounds-cool dept.
phmadore writes "10Gbps cables are what are commonly used in large server centers today, but very soon, according to Ars, 800Gbps cables will be available from Intel. From the article: 'The new cables are based on Intel's Silicon Photonics technology that pushes 25Gbps across each fiber. Last year, Intel demonstrated speeds of 100Gbps in each direction, using eight fibers. A new connector that goes by the name "MXC" holds up to 64 fibers ... The fiber technology also maintains its maximum speed over much greater distances than copper, sending 800Gbps at lengths up to 300 meters, Intel photonics technology lab director Mario Paniccia told Ars. Eventually, the industry could boost the per-line rate from 25Gbps to 50Gbps, doubling the overall throughput without adding fibers, he said.'"

    • Well if you just looked at the photos of the cables, you would see it is not a common consumer cable. It is a 64 optic fiber cable that does not exist in other fields. The Denon AKDL1 is simply an ethernet cable. AudioQuest Diamond is simply an HDMI cable. AudioQuest K2 is simply speaker cable. The Intel cable probably will be expensive but it will be used for back-bone usage and not consumer usage.

        Why aren't backbones using 100 Gbps (an established standard) and WDM for up to 88 channels of 100 Gbps? Though WDM is usually not used for shorter distances, you can already get 8.8 Tbps using commonly available commercial gear on 20 year old fiber.

          You mean besides cost? Yeah, that pesky factor that everyone is willing ignore because they want things now, now, now. Also just because the backbone is using high capacity fiber does not mean consumers will get it. Google is probably the biggest user of fiber out there and is certainly the biggest user of dark fiber. I'm sure Google is using the highest capacity they can get at a reasonable cost.

There's nothing compelling in this to get anyone to throw out a better network to adopt this. Yes, I'm sure it's lower power. Most 100Gbps DWDM is for longer distances, so you attenuate the signal for short distances. If it were optimized for shorter distances, it'd use 10-100x less power. We don't need a new standard to do that.
          • no, but it will have a ripple effect.

            If 800 per cable becomes the new standard, companies are going to start dumping their existing fiber connectors, and they will get cheap, and there will be less demand. The companies that make them, will most likely keep making the same or similx GBICs, because they already did the R&D, and they are cheaper to produce because the cost of design is already paid for.

          I work with 100 Gbps that runs over a single pair. And doesn't use DWDM, so you can run 88 channels of it, for 8.8 Tbps. On a single fiber. And the fiber can be 20+ year old single mode (though results depend on quality). Industry standard, no new cabling. Intel is solving a problem that doesn't exist. Or maybe coming up with something not-new in a cheaper price point. 88-channel DWDM is expensive. I think we are paying somewhere in the neighborhood of $1,000,000 per fully-populated 8.8Tbps link. But then, that's for optics capable of 1000+ mile transmission (with amplification). As the market is small for those speeds from server to switch or with any level of port density, so the price is not optimized for common use.

          So from what I can tell, this is less than 1/10th the speed of common industry standard gear, but cheap. Since when did stories about price breakthroughs get front page (other than solar)?

Or will their pencil pushers continue to view bandwidth as a scarce resource to be jealously guarded and sold for a kings' ransom?

    We've had cable and DSL modems out in customers' basements for years now that are capable of > 10-20 megabit speed, yet according to a recent Net

  • This tech looks cool. But, it's a bit surprising to me that we've not had any leaps in basic networking for a long time. Everything is gigabit ethernet. I thought 10Gbps Ethernet would have trickled down to some home usage by now.

    A 10Gbps connnection to my NAS, hypervisor, or server would be very useful. Or, just an uplink between switches.. But, I've not seen anything available.

      I'm with you. It drives me nuts that nothing better than 1Gbps has come along yet. Heck, I'd be thrilled with 5Gbps... it doesn't -have- to be 10Gbps.

        That is what silicon photonics is promising.

        Affordable fiber.

        Intel stated that 10gb becomes simple, cheaper, and power efficient once you get to 22nm. Once the prices of 22nm gets affordable to NIC manufacturers, expect to see 10gb copper NICs doing to 1gb what 1gb did to 100mb.

        Intel won't be using 22nm for non-CPUs until 14nm takes off. It will be a bit before we start to see chipset integrated 10gb, but not too far off. Would be nice to see these paired with PCIe4.0

  • Actually, at the UW, we already have three 100 Gbps ports - two in the 4545 building and one in the basement of the UW Tower. And a bunch of 40 Gbps ports around the Seattle campus.

    The surprising thing is there aren't any down at the UW Medical Center. Where you'd expect more demand.
