…development of several key technologies such as coherent detection, electronic dispersion compensation and Dual-Polarization Quadrature Phase Shift Keying (DP-QPSK) modulation.  In fact, Ciena holds more than 20 patents related to its work in 100G optical transmission.  Since its introduction, Ciena…

…technology and is uniquely tailored for the ultra-long haul requirements that come with submarine networks.  The other flavor is the more common DP-QPSK modulation format, which is also used in Reliance?s network for shorter spans where add/drop ROADM functionality is being used. By using Ciena?s coherent…

…developed several key technologies, including coherent detection, electronic dispersion compensation and Dual-Polarization Quadrature Phase Shift Keying (DP-QPSK) modulation. In August 2008, the Optical Internetworking Forum (OIF) acknowledged the strong performance of this approach, selecting it as the recommended…

…Ciena?s CN 4200 RS and CoreStream platforms.  A new 40G coherent module for the CN 4200 RS, due out in the second half of 2010, will bring in the DP QPSK modulation, coherent detection and electronic dispersion compensation features that have already been deployed with over 50 customers using the OME…

…formats are used?  WaveLogic 3 supports multiple coherent modulation formats.  * Dual-channel DP BPSK for 100G at trans-Pacific distances * DP QPSK for 100G Ultra Long Haul (single channel 100G) * DP 16QAM for 200G at metro and regional distances (two 100G waves in a single 50 GHz space) * Dual…
