ARTICLE OF THE HOUR Polarization in Fiber Systems
Squeezing out More Bandwidth
To appease the demand for bandwidth, telecommunication operators are pushed to increase the per-channel data rate of wavelength division multiplexing (WDM) systems. As bit rates increase to meet expanding demand, systems have become increasingly sensitive to polarization-related impairments. These include polarization mode dispersion (PMD) in optical fibers, polarization-dependent loss (PDL) in passive optical components, polarization-dependent modulation (PDM) in electro-optic modulators, ...more
