back to article Alca-Lu cooks up 400 Gbps router interconnect

Increasing data centre interconnect requirements have prompted Alcatel-Lucent to introduce 400 Gbps line cards for its high-end routers. Manish Gulyani, product marketing veep for the company's IP Business, told The Register there are multiple aims with the launch: it eliminates kit that would otherwise be needed to …

    Where's the datasheet?

    What's optic will it take?

    Oversubscription? Density/module?

    What spec does it conform to?

      @Ruairi

      Where's the datasheet?

      What's optic will it take?

      Oversubscription? Density/module?

      What spec does it conform to?

      Guess they've not released those yet.

      Took 2 secs to find a post on Alcatel Lucent website that states:

      About the Alcatel-Lucent 1-port 400G IP line card

      o Quadruples the speed of interconnecting today’s IP networks.

      o Alcatel-Lucent is the first in the industry to offer clear channel IP transport at 400G bit rates. This avoids the need to aggregate IP traffic over multiple 100G links. This offers a more efficient way to transmit big data between operators’ data centers and between their metro aggregation and core networks.

      o Powered by Alcatel-Lucent’s 400G FP3 routing silicon – already proven in hundreds of network deployments worldwide - allowing operators to use it with existing 7750 Service Router (SR) and 7950 Extensible Routing System (XRS) gear.

      o Integrated tuneable DWDM (dense wavelength division multiplexing) optics allow direct interconnection between routers at 400G line rates on a single fibre over distances of hundreds of kilometers, or alternatively as alien wavelengths over a DWDM transport network.

      o The 1-port 400G IP line card will be available for use in Alcatel-Lucent’s XRS IP Core Routers and on its 7750 SRs in the second-half of 2015.

      o Also introducing GMPLS UNI on the Alcatel-Lucent router portfolio to coordinate the IP and optical network layers for simplified operations and cost savings

    "The line cards can span between 500-600 km on a single fibre pair at full speed. "

    Blimey, that's a big datacentre! ;-)

      Nope, it's a big mess of optical cable in a normal sized data centre ;-)

      It's designed to stretch across Apples new HQ ;)

        Across? don't you mean around, so as to provide link redundancy between two servers in adjacent racks...

    Soon...

    Soon we'll have terabit connections and wonder where all the speed went.

    After people upgrade to Windows 12.
