Electromagnetic Spectrum Photonics: : 0.75  1.65  m f: THz } Microwaves f: 300MHz  300GHz : 1m  1mm } As carrier frequency increases, the same relative bandwidth means higher absolute bandwidth!

Communication Bandwidth Available in Optical Fiber Transmission Lines

Progress in Microelectronics

Improvement in system capacity Higher speed, more channels ,000 10, ,000 1,000,  Source: RHK System Capacity (Gbps)

Reduction in bandwidth cost Higher speed ， lower prices
