1. Ukuhlukaniswa kwebhizinisi lokuxhumana
Ngokwezinhlobo ezahlukene zezinsizakalo zokuxhumana, izinhlelo zokuxhumana zingahlukaniswa zibe izinhlelo zokuxhumana ngocingo, izinhlelo zokuxhumana ngocingo, izinhlelo zokuxhumana ngedatha, kanye nezinhlelo zokuxhumana ngezithombe.Ngenxa yokuthi inethiwekhi yokuxhumana ngocingo iyona ethuthuke kakhulu futhi ethandwa kakhulu, ezinye izinsiza zokuxhumana zivame ukudluliselwa ngenethiwekhi yokuxhumana ngocingo lomphakathi, njengokuxhumana ngocingo kanye nokuxhumana ngedatha amabanga amade, kungadluliswa ngeshaneli yocingo.Isevisi edidiyelwe yenethiwekhi yezokuxhumana yedijithali ifanele ukudluliswa kolwazi lwezinhlobo ezahlukene zezinsizakalo.
2. Ukuhlelwa okusekelwe ekuguquguqukeni
Ngokuya ngokuthi isignali edluliselwe esiteshini ishintshiwe yini, isistimu yokuxhumana ingahlukaniswa ibe isistimu yokudlulisa i-baseband kanye nesistimu yokudlulisa i-bandpass.Ukudluliswa kwe-Baseband ukudluliswa okuqondile kwamasiginali angashintshiwe, njengezingcingo zendawo kanye nokusakaza ngekhebula;ukudluliswa kwe-bandpass yigama elijwayelekile lokudlulisa okushintshiwe kwamasignali ahlukahlukene.Kunezindlela eziningi zokuguquguquka.Ithebula 1-1 yenza uhlu lwezindlela ezijwayelekile zokuguquguquka.
3. Ukuhlukaniswa ngokwezimpawu zesignali
Uhlelo lokuxhumana luhlukaniswe ngokufanayo lwaba uhlelo lokuxhumana lwe-analogue kanye nohlelo lokuxhumana lwedijithali ngokuya ngokuthi isignali ye-analogue noma isignali yedijithali idluliselwa esiteshini.
4. Transmission medium classification
Ngokwe-transmission medium, izinhlelo zokuxhumana zingahlukaniswa zibe izigaba ezimbili: izinhlelo zokuxhumana ezinezintambo kanye nezinhlelo zokuxhumana ezingenazintambo.Ukuxhumana okunezintambo kusebenzisa izintambo (njengezintambo ezihamba phezulu, izintambo eziqinile, ama-optical fibres, ama-waveguides, njll.) njengendlela yokudlulisela ukuze kuqedelwe ukuxhumana, njengocingo lwasendaweni, umabonakude wekhebula, ukuxhumana kwekhebula elingaphansi kolwandle, njll. Ukuze ukuxhumana okungenantambo kusebenze, amaza kagesi kufanele ahambe emkhathini.Lokhu kwenziwa ngokusebenzisa i-short-wave ionospheric propagation, i-microwave line-of-sight propagation, kanye nokudluliswa kwesathelayithi, phakathi kwezinye izinto.
5. Ukuhlukaniswa kwebhendi yokusebenza
Imishini yokuxhumana ihlukaniswe yaba ukuxhumana kwamagagasi amade, ukuxhumana namagagasi aphakathi nendawo, ukuxhumana ngamaza amafushane, ukuxhumana kwe-infrared ekude, njll., ngokusekelwe kufrikhwensi noma ubude begagasi lapho isebenza khona.
6. Ukwahlukanisa ngokuphindaphinda isignali
Kunezindlela ezintathu eziyisisekelo zokuphindaphinda zokudlulisa amasiginali ane-multiplex, okuyi-multiplexing ye-frequency division, i-multiplexing ye-time division, kanye ne-code division multiplexing.Ukuphindaphinda kwe-frequency division ukusebenzisa indlela yokuguqula i-spectrum ukwenza amasignali ahlukene athathe izigaba zamafrikhwensi ahlukene;i-time division multiplexing iwukusebenzisa indlela yokushintshashintsha kwe-pulse ukwenza amasignali ahlukene athathe izikhawu zesikhathi ezahlukene;futhi i-code division multiplexing iwukusebenzisa amakhodi e-orthogonal ukuphatha amasignali ahlukene, ngokulandelana.Isiginali.I-Frequency division multiplexing isetshenziswa ekuxhumaneni kwe-analogue yendabuko.Ngokuthuthuka kokuxhumana kwedijithali, uhlelo lokuxhumana lwe-multiplexing lokuhlukanisa isikhathi luya ngokuya lusetshenziswa kabanzi.I-Code division multiplexing isetshenziswa kakhulu ekuxhumaneni kwe-spectrum esakazwayo kanye nezinhlelo zokuxhumana zeselula zokuxhumana emkhathini.Ngaphezu kwalokho, kukhona i-wavelength division multiplexing, kanye ne-multiplexing yokuhlukanisa isikhala.
Okungenhla isihloko esithi “Ukuhlelwa Kwezinhlelo Zokuxhumana” olethwe kuwe ngabakwa-Shenzhen HDV phoelectron Technology Co., Ltd. ngethemba ukuthi lesi sihloko singakusiza ukukhulisa ulwazi lwakho.Ngaphandle kwalesi sihloko uma ufuna inkampani enhle yabakhiqizi bemishini yokuxhumana ye-fiber ongase uyicabangeleMayelana NATHI.
I-Shenzhen HDV phoelectron Technology Co., Ltd.ikakhulukazi umkhiqizi wemikhiqizo yezokuxhumana.Njengamanje, imishini ekhiqizwayo ihlanganisaUchungechunge lwe-ONU, optical module uchungechunge, Uchungechunge lwe-OLT, futhiuchungechunge lwe-transceiver.Singahlinzeka ngezinsizakalo ezenziwe ngezifiso ezimweni ezahlukahlukene.Wamukelekilebonisana.
