Makampani olankhulana ndi laser akukula mwachangu ndipo atsala pang'ono kulowa munyengo yachitukuko

Kulankhulana kwa laser ndi njira yolumikizirana pogwiritsa ntchito laser kufalitsa zidziwitso. Laser ndi mtundu watsopano wagwero lowala, yomwe ili ndi zizindikiro zowala kwambiri, kuwongolera mwamphamvu, monochromism yabwino ndi kugwirizana kolimba. Malingana ndi njira yopatsirana yosiyana, imatha kugawidwa mumlengalengaLaser kulankhulanandi optical fiber communication. Kulankhulana kwa Atmospheric laser ndi njira yolumikizirana ndi laser yogwiritsa ntchito mlengalenga ngati njira yopatsirana. Kulankhulana kwa fiber ndi njira yolankhulirana yogwiritsa ntchito kuwala kwa fiber kufalitsa ma siginecha.

Njira yolumikizirana ya laser imakhala ndi magawo awiri: kutumiza ndi kulandira. Gawo lopatsirana makamaka limapangidwa ndi laser, Optical modulator ndi optical transmitting antenna. Gawo lolandirira makamaka limaphatikizapo mlongoti wolandira kuwala, zosefera za kuwala ndiPhotodetector. Zomwe ziyenera kutumizidwa zimatumizidwa ku aOptical modulecholumikizidwa ndi laser, chomwe chimasintha chidziwitso palaserndikuzitumiza kudzera mu mlongoti wotumiza kuwala. Pamapeto olandira, mlongoti wolandira kuwala umalandira chizindikiro cha laser ndikuchitumiza kuchowunikira chowunikira, yomwe imatembenuza chizindikiro cha laser kukhala chizindikiro chamagetsi ndikuchisintha kukhala chidziwitso choyambirira pambuyo pa kukulitsa ndi kuchepetsa.

Setilaiti iliyonse mu Pentagon's mesh communications satellite network ikhoza kukhala ndi maulalo anayi a laser kuti athe kulumikizana ndi ma satellites, ndege, zombo ndi masiteshoni apansi.Maulalo a Opticalpakati pa masetilaiti ndizofunikira kwambiri kuti gulu lankhondo la US la Low-Earth orbit gulu lankhondo la US liziyenda bwino, lomwe lidzagwiritsidwe ntchito polumikizana ndi data pakati pa mapulaneti angapo. Ma Laser amatha kupereka ma data apamwamba kwambiri kuposa mauthenga achikhalidwe a RF, komanso ndi okwera mtengo kwambiri.

Asitikali aku US posachedwapa adapereka pafupifupi $ 1.8 biliyoni m'makontrakitala a pulogalamu ya 126 Constellation kuti imangidwe padera ndi makampani aku US omwe apanga ukadaulo wolumikizirana wamtundu umodzi mpaka wambiri wotumizira ma point-to-multipoint omwe angathandize kuchepetsa mtengo womanga kuwundana kwa nyenyezi pochepetsa kwambiri kufunikira kwa ma terminals. Kulumikizana kwa amodzi-ndi-ambiri kumatheka ndi chipangizo chotchedwa optical optical communication array (MOCA kwachidule), chomwe ndi chapadera chifukwa chimakhala modular, ndipo MOCA yoyendetsedwa ndi optical communication array imathandizira ma optical inter-satellite links kuti athe kuyankhulana nawo. ma satelayiti ena ambiri. Pakulankhulana kwachikhalidwe kwa laser, chilichonse chimakhala cholunjika, ubale umodzi ndi umodzi. Ndi MOCA, ulalo wa inter-satellite Optical umatha kuyankhula ndi ma satellite 40 osiyanasiyana. Ukadaulo uwu sikuti ndi phindu lokhalo lochepetsera mtengo womanga magulu a nyenyezi a satana, ngati mtengo wa node wachepetsedwa, pali mwayi wogwiritsa ntchito zomangamanga zosiyana siyana za maukonde motero milingo yosiyanasiyana yautumiki.

Kale, China Beidou Kanema anachita kuyesera laser kulankhulana, bwinobwino kupatsira chizindikiro mu mawonekedwe a laser pansi kulandira siteshoni, amene ali ndi tanthauzo lapadera kwa mkulu-liwiro kulankhulana pakati pa maukonde Kanema m'tsogolo, ntchito laser. Kuyankhulana kungathe kulola satelayiti kufalitsa ma megabits masauzande a deta pamphindikati, kuthamanga kwa moyo wathu watsiku ndi tsiku ndi megabits pang'ono kufika pa megabits khumi pamphindikati, ndipo kamodzi kulankhulana kwa laser kukuchitika, Kuthamanga kutha kufika pa gigabytes angapo pamphindi, ndipo m'tsogolomu. imathanso kupangidwa kukhala ma terabytes.

Pakali pano, China Beidou panyanja dongosolo wasaina mapangano mgwirizano ndi mayiko 137 padziko lonse, ali ndi chikoka zina padziko lapansi, ndipo adzapitiriza kukula m'tsogolo, ngakhale China Beidou navigation dongosolo ndi gulu lachitatu la okhwima Kanema panyanja dongosolo, koma ili ndi ma satelayiti ochuluka kwambiri, ngakhalenso kuposa ma satellite a GPS. Pakadali pano, njira yapanyanja ya Beidou imagwira ntchito yofunika kwambiri pamagulu ankhondo komanso anthu wamba. Ngati kulumikizana kwa laser kungatheke, kudzabweretsa uthenga wabwino padziko lapansi.
