Optical Multiple-Access Techniques,an be classified into two categories based on their physical nature: optical and electrical. This chapter introduces three major optical multiplexing technologies: WDM (wavelength division multiplexing), SDM (space division multiplexing), and PDM (polarization division multiplexing). For TDM (time d
