    100Tbps+...maybe I need a new system

    http://www.techspot.com/news/43594-r...cal-fiber.html

    At the Optical Fiber Communications Conference in Los Angeles last month, two separate research groups have set a world record by sending information at rate of more than 100 terabits of per second (Tbps) through a single optical fiber.


    NEC Laboratories America reached 101.7 Tbps over standard single-mode fiber using pilot-based phase noise mitigation. The team sent 370 wavelengths each with data rates of 294 Gbps over 165km of standard single-mode fiber, and claimed it achieved spectral efficiency of 11 bits/s/Hz, the highest reported to date for wavelength-division multiplexing transmission. A separate team from Sumitomo Electric Industries in Japan, demonstrated 109Tbps using spatial division multiplexed signals over a seven-core fiber. The Sumitomo group sent 97 colors through each of the cores at data rates of 172Gbps (two 86Gbps QPSK signals) over 16.8 km of fiber.

    So $9.99 can go to finance research like this.

    Lets not get into another debate on.. Why do we pay what we pay for transit again.

    I'm gonna go kick the dead horse a few more times.

    Amazing.
    Now that the research is done implement it on my home network for a far price.

    Because I'm certain that above all other things, you have the IO capacity to actually handle 100Tbps to your curb.

    100tbps at city level, 1gbps to everyone.
    I can't belive I've replied.

    That is phenomenal, and to think that Cisco exams still quote 300Mbps through fibre optic

    To me the NEC one is MUCH more impressive. Longer distance and over a single fiber, not using 7 cores.

    And considering 100 GigE cards + optics are still ~$200k a port, at least last I checked, these won't be cheap either. That isn't even looking at regens/amps for longer distance DWDM applications/long haul, etc. I find it interesting how people don't seem to understand the massive cap-ex cost in running these networks...

    that must be what 100tb.com has been using secretly LOL

    on a serious note : simply wow

    looks skywards

    Thats the easy bit done, breadboarding a point to point research network.

    Now the tricky part of rasing the multi trillion CapEx needed to switch it.
