The effect of filtering on the OSNR For a 40- and 100 Gb/s DWDM system
Paper i proceeding, 2014
Quality measures like Bit Error Rate (BER) and Optical Signal to Noise Ratio (OSNR) are important indicators for verifying the quality of a received signal in the optical fiber communication. Different components like Wavelength Selective Switches and Optical Interleaver Units used in a Dense Wavelength Division Multiplexed network can decrease the operating bandwidth. This work investigates the effect of bandwidth narrowing on the OSNR value in an optical fiber link.
