NYC's Educational Dark Fiber Network 101

Posted by timothy from the you-only-use-10-percent dept.
An anonymous reader submits "A group of educational leaders in New York City has created a new fiber backbone network off previously layed but unused fiber. Connecting many city NYSERNet members (the Museum of Natural History, CUNY, Mt. Sinai-NYU Medical, Cornell Med., Columbia Med., and Columbia's primary campus), the newly activated backbone connects to Internet2 and commodity Internet and intends to be largely used for video streaming. Original plan info here."

      Yes, there is a lot. During the dot-com boom lots of companies/startups were running and laying fiber. Since the dot-com bust, all the fiber became unlit and hence dark fiber.

      In Ohio we've recently completed our Third Frontier Network [osc.edu] which was largely built from dark fiber.

        The main reason for a glut of dark fiber is not actually the dot-com bust, contrary to popular belief. The main reason is the use of Dense Wave Division Multiplexing (DWDM). This allows A LOT more data to be sent over the same pipe as before, thus rendering the majority of that fiber useless. Don't get me wrong, the dot-com bust had a MAJOR impact on the use of fiber, but it wasn't the main factor in the dark fiber glut.

          I think it is more likely that DWDM equipment allows fiber someone already owns to be used more efficiently. I don't know of any company that gets rid of fiber they have because they put DWDM on a couple of strands. Its like saying that there are more video games on the market because we all have more free time now days. Sure, DWDM lets you cram more data down a particular strand of fiber, but the need for capacity is increasing too, and laying new fiber is very expensive (especially transoceanic fiber).
          • I didn't say that they got rid of fiber, or maybe I didn't make myself clear. DWDM didn't cause anyone to get rid of fiber, it just means that there is a lot of UNUSED fiber. There is an enormous potential for bandwidth that was brought about by DWDM, but the expense is whats holding it back. The problem is that there will always be limited fund, thus limited bandwidth.

        This isn't the only source of unused fiber - The majority of the fiber in the ground has never been lit. It costs almost as much to lay one strand as a hundred, so everybody laid a hundred, plus empty conduit it could be blown through later. The stuff on the ends however, is expensive, so they don't light it till they need it.

      most of the cost of running fiber anywhere is backhoe. once you've dug a trench, the cost implications for adding double the amount of fiber/cable you actually need is negligible - so you put loads in to allow for future expansion. this extra fiber just sits there until it's needed, or until other fiber breaks and is swapped over to the spare capacity...
    • Ya know... in the US we have slower bandwidth than most of the other tech countries of the world. It's not for lack of the fiber being there. It's more controls on the speeds so when they increase it a little we compare it to ourselves not what else is out there.

      Glad to see someone using some of it for somethign productive.
    • At times during the bubble, for every used fibre there were 100 dark ones.
      The material of the fibre isnt the cost factor, its the electronics driving them. So its easy to just dump a whole bunch instead a single one into the ground and buy the trancievers years later...

    what kind of video gets streamed from a natural history museum to a hospital? More seriously, here in Denmark, the electricity companies want to get in on the game, but nobady really knows where all that fiber got dumped during the bubble. One company ordered fiber along a road, and then found out there was already dark fiber: the company they asked to dig the trenches had also dug the previous ones. If it was me, I would have kept my mouth shut, but then again...
    • Maybe the hospital and the museum shouldn't be connected by the Internet, either? They're connected because they both generate and consume bandwidth, and they're people - they will communicate with each other if they can. We build networks for people, not data - and these people are researchers, inventing the future. In five years, look back at what video they did stream, and learn - that's this community's specialty.
    • I don't know about the museum but I do know that hospitals sometimes stream live feeds from operations. That's one possible use. Since this is in some way connected to education a network like this could probably be used to give classes by streaming them to the students. A sufficiently high resolution image would be needed (how else would they make out what their professor is cutting in) so a big pipe would probably come in handy.

    Having dark capacity isn't surprising when you look at the economics.

    2. Cost of laying 24 strands of fiber:

    At the time I worked for the local DOT, they laid 22 odd strands of fiber down the major highways in town, and used the revenue generated from selling off fiber to halp fund the project. It's good for the DOT as it lowers costs, and it's good for Telco/ISP/whoever because they don't have to dig a seonc trench, obtain permission, rip up roads again, etc.

    Monterey County CA, the maintenance guys were looking in some "unmarked" panels in the basement in the Salinas offices, and "found" about 200 strands of dark fiber. Apparently during the reign of one of the iterations of our local cable service (TCI/AT&T/Comcast, AT&T did it I know it :), they "knew" that fiber was the future and laid fiber all over the place, then they sold out to comcast without hooking any of it up.

    Montery started by connecting to schools and cities down the 101 highway, when MCOE lost antenna space for their educational television feed, they ran it down the fiber backbone, without causing any lag in any of the connections. So now places that were running 56k frame relays are now flying with 45mb to their router. They actually have a bigger connection than my isp :)

I am sure there is a great deal of it laying out there along the roadside, in the sewers, and under the sidewalks just waiting for an application. Unfortunately, it's a pain in the ass to find out who owns what, and who to contact in your area. Some maps or perhaps a dark fiber market would be nice. Any suggestions?

I have a map that shows me exactly where my fiber goes. (No, I can't share it with you.)
    • So "dark fiber" is not really the correct word here. BTW, I have NEVER seen the article's definition for dark fiber used before, I have always seen it used to describe the excess unlit fiber that is always installed when someone runs fiber. As many earlier posters pointed out, in most situations (especially long-haul ones that involve digging), the cost of running 100 fibers instead of one is insignificant compared to the cost of digging a hole to install the fiber in.
      • Yes "dark" is the right term. It means no telco is lighting it with their SONET or whatever equipment and then selling me a managed service. We have 20-year rights to several strands of actual glass end-to-end which we can light with whatever we want. We could send morse code by flashlight (torch for the bloody UK poster:-) but instead we chose to start with 10 gigabit Ethernet. I think the term you are looking for describing previsouly laid and unproductive fiber is "distressed assets." ;-)

    Columbia's announcement says they've increased their internet connectivity to ~300 Mbps, from their previous 150 Mbps. Seems kind of wimpy - I'd have expected an announcement that says they're running at least gigabit connections to the other participants in the study. Maybe they're doing that and the press release just doesn't mention it? Or did they just start cheap and reuse their existing OC3 cards, while maybe some of the other players have fast connections to each other?

    If you wade through the piles of documentation, it looks like they've got dark fiber routes from each of the participants to racks at a couple of hub locations where they can meet with each other and Nysernet and also crossconnect to other carriers at a carrier-neutral facility. That means they could be running whatever combination they want of DWDM or CWDM, 10 Gig Ether, 1 Gig Ether, or traditional SONET (155 Mbps x 1,4,16,64) depending on how much they want to spend on CPE. I couldn't tell how many fiber pairs they were deploying per customer, but they're using fairly new high-end fiber that supports almost anything. The cheapest way to light up the stuff is with GigE fiber connections, since you can get by with a pretty small router, and cheap cards for short-distance hops, but CWDM is coming down in price (Coarse Wavelength Division Multiplexing doesn't get as many channels per fiber as Dense Wavelength Division Multiplexing, but the hardware's a lot cheaper) so you should be able to run multiple GigEs or whatever else you feel like. It looks like hardware costs for the CWDM versions are on the order of $5-10K per FDX GigE channel.

    • If their infrastructure compares anything to the CT Edu. Network, they probably are using OC3 interfaces on their edge routers to the POP but internal GigE within NYSERNET. (CEN uses gigE between routers, and ATM/OC-3 to the actual Internets), so if Columbia is merely talking about capacity out of their ISP, then they may have faster intranet links.
