…significant economic benefits through the reduction or elimination of a variety of network equipment such as amplifiers, regenerators, and dispersion and PMD compensators * Avoid new fiber installation with the ability to use 10G-marginal fiber for 40G and 100G transmission * Fully satisfy customer expectations…

…over impaired fiber that cannot be used for 10Gbps without the need for separate optical Chromatic Dispersion (CD) and Polarization Mode Dispersion (PMD) compensators.  With an in-service upgrade, existing CN 4200 customers can obtain a four-fold increase in capacity with existing ROADM schemes,…

…additional in-line amplifiers or regeneration equipment (which of course adds cost to the network).  Additionally, polarization mode dispersion (or PMD) is increased 4X with 40G and 10X with 100G versus traditional 10G transmission.  Chromatic dispersion is 16X worse at 40G and100X worse at 100G…
