Getting Religious with Coherent Technologies in High-Speed Optical Access Systems
Coherent technologies offer promising solutions for high-speed optical access beyond the rate of 100 Gb/s. By embracing coherent detection, optical access system capacity can be enhanced by encoding information in amplitude, phase, as well as polarization components of a carrier. With the use of digital signal processing (DSP), coherent receivers can mitigate signal impairments through the use of distortion equalization and fiber dispersion compensation. Compared to Intensity Modulation / Direct...
