Ukuhlangabezana nesidingo esandayo sabantu semininingwane, izinga lokudlulisa le-Optical Fibriection Systems landa usuku nosuku. Inethiwekhi yokuxhumana yesikhathi esizayo izothuthukisa inethiwekhi yezokuxhumana ye-Optical Fibrical enejubane eliphezulu, i-Ultra-Imali enkulu, ibanga elide le-Ultra-high. I-Transmitter ibalulekile. I-Transmitter ye-High-Speed Speed SINGALS ihlanganiswe ne-laser ekhiqiza i-Optical Carrier, idivaysi eguqukayo kagesi ekhiqizayo, kanye ne-electro-speed electro-optical modulator eguqula i-Optical Carriers. Uma kuqhathaniswa nezinye izinhlobo zama-modulators angaphandle, ama-lithium niobate ectron-optical modro anezinzuzo zemvamisa ebanzi, ukuqina okuqinile, ukuhlanganiswa okuphezulu, ukuhlanganiswa okuvuthiwe, ukuhambisa okuvuthiwe, kusetshenziswa amasistimu wokuhambisa amabanga amancane.
I-Half-Wave Voltage iyipharamitha ebaluleke kakhulu yomzimba ye-electro-optic modulator. Imelela ushintsho ku-BIAS VOLTTAGE ehambelana namandla okukhanya okukhanya kwe-electro-optic modulator kusuka kubuncane kuya kokuphezulu. Inquma i-electro-optic modulator ngezinga elikhulu. Ungakulinganisa kanjani ngokunembile futhi ngokushesha ukulinganisa ama-voltage we-Half-wave we-electro-optic modulator kubaluleke kakhulu ekwakheni ukusebenza kwensiza kanye nokwenza ngcono ukusebenza kahle kwensiza. I-Half-Wave Voltage ye-Electro-Optic Modulator ifaka i-DC (Half-Wave
I-Voltage ne-Radiofrequency) Voltage Half-Wave Voltage. Umsebenzi wokudlulisa we-Electro-Optic Modulator umi kanjena:
Phakathi kwazo kungamandla okuphuma we-electro-optic modulator;
Ngumbuso obonakalayo we-modulator;
Ukuwohloka kokufaka kwe-electro-optic modulator;
Izindlela ezikhona zokulinganisa i-Half-wave voltage zifaka phakathi imali yenani elibi kakhulu kanye nezindlela zokuphindaphindeka eziphindaphindeka, ezingalinganisa i-voltage eqondile yamanje (DC) ye-Half-wave voltage ne-radio frequency of modulator, ngokulandelana.
Ithebula 1 Ukuqhathaniswa kwezindlela ezimbili zokuhlola ze-Voltage Voltage
| Indlela Yenani Elikhulu | Indlela yemvamisa ye-Frequency | |

Isebenza kanjena:
(1) indlela yenani elikhulu kakhulu
Indlela yenani eleqisayo isetshenziselwa ukukala i-VoLtage ye-DC Half-Wave ye-Electro-Optic Modulator. Okokuqala, ngaphandle kwesiginali yokushintshanisa, ijika lomsebenzi wokudlulisa le-electro-optic modulator litholakala ngokulinganisa i-VC BIAS VOLTAGE kanye nokushintshwa komsebenzi wokukhipha, futhi uthole amanani we-VC Voltage Voltage, bese uthola ngokulandelana. Okokugcina, umehluko phakathi kwalawa manani amabili kagesi yi-Half-wave voltage vπ = vmax-vmin ye-electro-optic modulator.
(2) Indlela yokuphindaphinda i-Frequency
Bekusebenzisa indlela yokuphindaphinda kaningi ukukala amandla kagesi we-RF Half we-Electro-Optic Modulator. Ngeza ikhompyutha ye-DC Bias Computer kanye ne-AC Modal Signal ku-Electro-Optic Modulator ngasikhathi sinye ukulungisa i-DC Voltage lapho ukuqina kokukhanya kushintshiwe kube yinani eliphakeme noma elincane. Ngasikhathi sinye, futhi kungahle kubhekwe e-Oscilloscope ye-Dual-Trace ukuthi kuzovela isiginali esezingeni eliphakeme azovela imvamisa. Umehluko wodwa we-DC Voltage ehambelana nokuhlanekezelwa okuzayo okusondelene kwamandla okuphindaphindwayo yi-voltage ye-RF Half ye-actro-optic modulator.
Isifinyezo: Zombili indlela yenani elikhulu kakhulu kanye ne-Frequency Okuphindaphindiwe Indlela ingalinganisa amavolumu we-Half-Wave Modulator we-Electro-Optic Modulator, kepha indlela yenani elinamandla idinga amandla okuphuma kwe-laser flueff flueff kanye nebangela amaphutha wokulinganisa. Indlela yenani elikhulu kakhulu idinga ukuskena i-DC BIAS ngenani lesinyathelo esincane bese irekhodiwe amandla okuphuma kwesilungiselelo ngasikhathi sinye ukuthola inani elinembe ka-DC Half-Wave Voltage Value ngasikhathi sinye ukuthola inani elinembile le-DC Half-Wave Voltage Value ngasikhathi sinye ukuthola inani elinembile le-DC Half-Wave Voltage Value ngasikhathi sinye ukuthola inani elinembile le-DC Half-Wave Voltage Value ngasikhathi sinye ukuthola inani elinembile le-DC Half-Wave Voltage Value ngasikhathi sinye ukuthola inani elinembile le-DC Half-Wave Voltage Value ngasikhathi sinye.
Indlela yokuphinda kabili ephinda kabili yindlela yokuthola i-Half-Wave Voltage ngokubheka i-Frequency Everal Waveform. Lapho i-applection bias Voltage ifinyelela inani elithile, ukuthuthukiswa kokuphindaphindwa kwenzeka kwenzeka, futhi ukuphambuka kwe-waveform akubonakali kakhulu. Akulula ukubona ngeso elinqunu. Ngale ndlela, kuzodala amaphutha abalulekile kakhulu, nokuthi yiziphi izinyathelo i-voltage ye-RF Half-Wave Modulator ye-Electro-Optic Modulator.
