Analog and Digital Modulation Formats of Optical Fiber Communication within and beyond 100 Gb/s: a Comparative Overview
نویسنده
چکیده
For transferring data to increase performance and implementation simplicity different analogue and digital techniques are used in fiber optic communication channel. Different digital modulation formats maximizes spectral efficiency and also improves tolerance to transmission impairments. This paper reviews a comparative analysis for the different digital modulation formats within 100Gb/s and beyond the 100Gb/s. A brief overview over different transmission systems transmitting huge amount of data at channel bit rates up to 1Tb/s or beyond this. In this specific article we survey in a comparative tabular manner to analyse the advantages of digital modulation formats over old analogue modulation formats.
