…solutions.  The piece of today?s announcement that is likely to get the most headlines is that WaveLogic 3 can scale to 400G, but there is much more to the news than just 400G.  To get you quickly up-to-speed, here’s a run-down on what you need to know along with links to additional resources…

…has motivated many optical systems vendors to bring to market their own coherent solutions to provide a path for optical transport speeds of 100G, 400G and even 1Tbps. However, now that the entire optical vendor market is scampering to implement this key technology, a challenge has come to the surface…

…end with 100G.  That’s why Ciena is already working on future generations of its WaveLogic coherent optical processors that will scale to 400G and Terabit (1Tbps) speeds.  These new generations will feature technology advancements such as soft decision forward error correction (soft FEC…

…coherent optical processors that support 10G, 40G and 100G wavelengths working side by side.  BT also highlighted the desire to eventually move to 400G speeds using the Ciena platform (see below quote).  Commercial roll-out is scheduled to begin by the end of 2011, and the initial deployment will…

…equipped with Raman amplifiers. All equipment in this demonstration is commercially available. • Terabit and 400G Transmission: Ciena will show 400G performance data from a 400G demonstration and a video from a Terabit demonstration from a customer event held in October 2010 that are powered by…

…vastly expand capacity without disrupting existing networks, providing simple and cost-effective upgrades from 10G to 40G or 100G, with a clear path to 400G. That’s game-changing. * Recent news:  BT Expands 21CN Using Ciena?s Next Generation of High Bandwidth Optical DWDM Technology (press release…

…400G per wavelength is looking feasible with an improved spectral efficiency compared to 100G on 50GHz grid, but it is somewhat doubtful that 1T per wavelength can further improve on this while maintaining adequate reach. Consequently, while I expect that there will be plenty of people saying that 400G…

…evolution of carrier networks, it is very likely not the end game.  The industry is already debating how to push capacities further, and whether 400G is the next step or if carriers should wait for Terabit (1Tbps) availability.  Sounds kind of like the 40G vs 100G debate, doesn?t it?   And…

…at the gear we had on display. * Under the topic of “what’s next” from the show, there was the obvious talk of faster speeds like 400G and Terabit.  Additionally, the idea of “tunable bandwidth” came up in several discussions.  The idea here is that a coherent…
