Utloisisa bolelele ba maqhubu a 850nm, 1310nm le 1550nm ka fiber optical
Khanya e hlalosoa ka bolelele ba maqhubu a eona, 'me ho likhokahano tsa fiber optic, leseli le sebelisoang le sebakeng sa infrared, moo bolelele ba maqhubu a khanya bo fetang ba khanya e bonahalang. Puisanong ea fiber ea optical, bolelele bo tloaelehileng ke 800 ho 1600nm, 'me maqhubu a sebelisoang haholo ke 850nm, 1310nm le 1550nm.
Mohloli oa setšoantšo:
Ha fluxlight e khetha bolelele ba phetisetso, haholo-holo e nahana ka tahlehelo ea fiber le ho hasana. Sepheo ke ho fetisa lintlha tse ngata ka tahlehelo e fokolang ea fiber sebakeng se selelele ka ho fetisisa. Ho lahleheloa ke matla a pontšo nakong ea phetisetso ke ho fokotsa. The attenuation e amana le bolelele ba waveform, ha leqhubu le le lelelele, ho fokotseha ho nyane. Leseli le sebelisoang ka har'a fiber le na le leqhubu le lelelele ho 850, 1310, 1550nm, kahoo ho fokotseha ha fiber ho fokotseha, e leng se hlahisang tahlehelo e fokolang ea fiber. 'Me maqhubu ana a mararo a na le hoo e ka bang zero absorption, e leng tse loketseng haholo bakeng sa ho fetisoa ka likhoele tsa optical e le mehloli ea leseli e fumanehang.

Puisanong ea fiber ea optical, fiber ea optical e ka aroloa ka mokhoa o le mong le oa mefuta e mengata. Sebaka sa 850nm wavelength hangata ke mokhoa oa puisano oa mefuta e mengata ea optical fiber, 1550nm ke mokhoa o le mong, 'me 1310nm e na le mefuta e' meli ea mokhoa o le mong le oa mekhoa e mengata. Ha e bua ka ITU-T, ho fokotseha ha 1310nm ho khothalletsoa hore e be ≤0.4dB / km, 'me ho fokotseha ha 1550nm ke ≤0.3dB / km. Mme tahlehelo ho 850nm ke 2.5dB/km. Tahlehelo ea fiber hangata e fokotseha ha maqhubu a ntse a eketseha. Bohareng ba wavelength ea 1550 nm ho potoloha C-band (1525-1565nm) hangata e bitsoa fensetere ea zero loss, ho bolelang hore ho fokotsoa ha fiber ea quartz ke e nyane ka ho fetisisa boleleleng bona ba maqhubu.
