PLC Enables 40-100G NGN

The availability of bandwidth intensive services such as Fiber-to-the-Home, along with bandwidth requirements in the commercial sector, have created a growing demand for the introduction of new 40G/100G optical networks. Many of these new systems rely on advanced modulation formats like Differential Phase Shift Keying (DPSK), and Differential Quadrature Phase Shift Keying (DPQSK), to complement more traditional architectures like Dense Wavelength Division Multiplexing (DWDM). Each of these methods presents substantial optical, mechanical, and electronic complexity. Traditional bulk-optic assemblies can in some cases achieve the required complexity in relatively low volumes, but have substantial problems meeting the additional requirements of volume manufacturability, compactness, ruggedness, and low-cost.
