Ishishini lonxibelelwano nge-laser likhula ngokukhawuleza kwaye liza kungena kwixesha legolide lophuhliso
Unxibelelwano nge-laser luhlobo lwendlela yonxibelelwano esebenzisa i-laser ukudlulisa ulwazi. I-laser luhlobo olutsha lweumthombo wokukhanya, eneempawu zokukhanya okuphezulu, isikhokelo esinamandla, i-monochromism elungileyo kunye nokuhambelana okuqinileyo. Ngokweendlela ezahlukeneyo zokudlulisa, inokwahlulwahlulwa ibe yi-atmosphericunxibelelwano lwelaserkunye nonxibelelwano lwefayibha ye-optical. Unxibelelwano lwelaser yomoya lunxibelelwano lwelaser olusebenzisa umoya njengendlela yokudlulisela. Unxibelelwano lwefayibha ye-optical luyindlela yonxibelelwano olusebenzisa ifayibha ye-optical ukuhambisa imiqondiso ye-optical.
Inkqubo yonxibelelwano lwelaser inamacandelo amabini: ukuthumela nokufumana. Inxalenye yokuthumela ikakhulu iquka ilaser, i-Optical modulator kunye ne-optical transmitting antenna. Inxalenye yokwamkela ikakhulu iquka i-optical receiving antenna, i-optical filter kunye ne-optical filter.Isixhobo sokubona iifotoUlwazi oluza kudluliselwa luthunyelwa kuImodulator yokubonisaiqhagamshelwe kwi-laser, eguqula ulwazi olukwi-ilezakwaye iyithumela nge-antenna yokudlulisa ebonakalayo. Kwicala lokwamkela, i-antenna yokwamkela ebonakalayo ifumana isignali yelaser ize iyithumele kwiisixhobo sokubona, eguqula isignali yelaser ibe sisignali yombane ize iyiguqule ibe lulwazi lokuqala emva kokwandiswa kunye nokususwa kombane.
Isathelayithi nganye kwinethiwekhi yesathelayithi yonxibelelwano lwe-mesh ecwangcisiweyo yePentagon inokuba neekhonkco ezine ze-laser ukuze ikwazi ukunxibelelana nezinye iisathelayithi, iinqwelo-moya, iinqanawa kunye nezikhululo zomhlaba.Amakhonkco okukhanyaphakathi kweesathelayithi kubalulekile kwimpumelelo yeqela lemikhosi yase-US elijikeleza uMhlaba ophantsi, eliza kusetyenziselwa unxibelelwano lwedatha phakathi kweeplanethi ezininzi. Iilaser zinokubonelela ngamanani aphezulu okudluliselwa kwedatha kunonxibelelwano lweRF lwendabuko, kodwa zikwabiza kakhulu.
Umkhosi wase-US usandula ukunika izivumelwano eziphantse zibe yi-1.8 yeebhiliyoni zeerandi zenkqubo yeConstellation eyi-126 eza kwakhiwa ngokwahlukeneyo ziinkampani zase-US eziphuhlise itekhnoloji yonxibelelwano lwe-optical eyodwa ukuya kweninzi yokudlulisela i-point-to-multipoint enokunceda ukunciphisa iindleko zokwakha i-constellation ngokunciphisa kakhulu imfuneko yee-terminals. Uqhagamshelo lwe-one-to-many lufezekiswa sisixhobo esibizwa ngokuba yi-managed optical communication array (i-MOCA ngamafutshane), esikhethekileyo kuba si-modular kakhulu, kwaye i-MOCA managed optical communication array ivumela amakhonkco e-optical inter-satellite ukunxibelelana nezinye ii-satellite ezininzi. Kunxibelelwano lwe-laser yendabuko, yonke into i-point-to-point, ubudlelwane be-one-to-one. Nge-MOCA, ikhonkco le-optical phakathi kwe-satellite linokuthetha nee-satellites ezingama-40 ezahlukeneyo. Le teknoloji ayisiyonto nje yokunciphisa iindleko zokwakha ii-constellations ze-satellite, ukuba iindleko zee-nodes zincitshisiwe, kukho ithuba lokuphumeza uyilo lwenethiwekhi ezahlukeneyo kwaye ngaloo ndlela amanqanaba enkonzo ahlukeneyo.
Kwixesha elidlulileyo, i-Beidou satellite yaseTshayina yenze uvavanyo lonxibelelwano lwe-laser, yadlulisela ngempumelelo isignali ngendlela ye-laser kwisikhululo sokwamkela emhlabeni, nto leyo ebaluleke kakhulu kunxibelelwano olukhawulezayo phakathi kweenethiwekhi zesathelayithi kwixesha elizayo, ukusetyenziswa konxibelelwano lwe-laser kunokuvumela i-satellite ukuba idlulisele amawaka ee-megabits zedatha ngomzuzwana, isantya sethu sokukhuphela ubomi bemihla ngemihla si-megabits ezimbalwa ukuya kwi-megabits ezilishumi ngomzuzwana, kwaye xa unxibelelwano lwe-laser lufezekisiwe, isantya sokukhuphela sinokufikelela kwii-gigabytes ezininzi ngomzuzwana, kwaye kwixesha elizayo sinokuphuhliswa sibe zii-terabytes.
Okwangoku, inkqubo yokuhamba ngenqanawa yaseTshayina iBeidou isayine izivumelwano zentsebenziswano namazwe ali-137 kwihlabathi liphela, inempembelelo ethile kwihlabathi liphela, kwaye iya kuqhubeka isanda kwixesha elizayo, nangona inkqubo yokuhamba ngenqanawa yaseTshayina iBeidou iseti yesithathu yenkqubo yokuhamba ngesatellite evuthiweyo, kodwa inenani elikhulu leesathelayithi, nangaphezulu kunenani leesathelayithi zenkqubo yeGPS. Okwangoku, inkqubo yokuhamba ngenqanawa yaseBeidou idlala indima ebalulekileyo kwicandelo lomkhosi nakwintsimi yoluntu. Ukuba unxibelelwano lwelaser lunokufezekiswa, luya kuzisa iindaba ezimnandi kwihlabathi.
