In terms of digital communications, how to expand the capacity of C-band amplifiers, overcome the deterioration of fiber dispersion effects, and increase the capacity and range of free-space transmission have become important considerations for researchers;On the other hand, in terms of analog communication, sensitivity and dynamic range are key parameters of the system.
Ngokuxhumana kwe-digital, indlela yokwandisa amandla we-C-band amplifiers, ukunqoba ukuwohloka kwemiphumela yokusabalalisa kwefayibha, nokwandisa amandla kanye nobubanzi bokudlulisa isikhala samahhala kube yizinto ezibalulekile kubacwaningi; Ngakolunye uhlangothi, ngokwemibandela kokuxhumana kwe-analog, ukuzwela kanye nobubanzi obushukumisayo yimingcele ebalulekile yesistimu.
