U-Paidu ungumkhiqizi nomphakeli waseChina okhiqiza ngokuyinhloko ama-Solar Cable Optical Voltages aneminyaka eminingi yesipiliyoni. I-Voltage isho umehluko ongaba khona kagesi phakathi kwamaphoyinti amabili kusekethe kagesi. Ngomongo wezintambo zelanga, sivame ukukhuluma ngesilinganiso samandla kagesi wekhebula, okubonisa ubukhulu be-voltage ikhebula engakwazi ukuyiphatha ngokuphephile ngaphandle kokuwohloka noma ukwehluleka ukuhlukanisa. Lesi silinganiso samandla kagesi ngokuvamile sicaciswa ngama-volts (V) noma ama-kilovolts (kV).Uma ubuza "ngama-voltage okukhanya kwekhebula yelanga," kungase kube ukungaqondi kahle noma igama elingelona iqiniso. Amakhebuli elanga awahlobene nama-optical voltages njengoba enzelwe ukuthwala amandla kagesi, hhayi amasignali abonakalayo. Kodwa-ke, uma ungathanda ukusebenzisa ubuchwepheshe befiber optical kumasistimu wamandla elanga ukudlulisa idatha noma izinjongo zokuqapha, ungase ucabange ukuhlanganisa ama-optical fibre eduze kwezintambo zikagesi ezivamile ukuze udlulise idatha kusuka kuzinzwa, iziguquli, noma izisetshenziswa zokuqapha zibuyisele kusistimu yokulawula emaphakathi.
