Maluso owoneka bwino ndi ukwati wawo wa pa-chip ndiKuyankhulana kwatseko: kuwunikira

Njira zosinthika za kusinthika ndi mutu wofufuzira mwachangu, ndipo akatswiri onse padziko lonse lapansi akuchititsa kuti anthu azikhala akuzama m'munda uno. Kwa zaka zambiri, matekinoloje ambiri a Milwection monga kuchuluka kwa kuchuluka (WDM), mawonekedwe a magawo angapo (MDM), polation Divising inxing (ORM) ndi maofesi) afunsidwa. Unduna wa Highlength Mexing (WDM) umathandizira zizindikiro ziwiri kapena zingapo za magwero osiyanasiyana kuti afalitsidwe kudzera mu ulusi umodzi, ndikugwiritsa ntchito mapangidwe otsika a fiber pamlingo waukulu. Chiphunzitsocho chinafunsidwa koyamba ndi delaange mu 1970, ndipo mpaka 1977 kuti kafukufuku woyamba wa ukadaulo wa WDM adayamba, zomwe zimangoganiza za kugwiritsa ntchito ma network. Kuyambira pamenepo, ndikupitiliza kupitilizabefiberi yota, gwero loyera, chithunzindi minda ina, kufufuza kwa anthu mwaukadaulo wa WDM kwathandizanso. Ubwino wa polarization Disxing (PDM) ndikuti kuchuluka kwa kufalitsa chizindikiro kumatha kuchulukana, chifukwa ma signals awiri odziyimira paofesi omwewo amapatulidwa.

Monga momwe kufunikira kwapamwamba kumapitilira, digiri yomaliza ya ufulu wamakono, malo, adaphunzitsidwa kwambiri pazaka khumi zapitazi. Zina mwa izo, mawonekedwe ogawana masinthidwe (MDM) amapangidwa ndi n n kusuntha, zomwe zimadziwika ndi mawonekedwe a spatial. Pomaliza, chizindikirocho chikuthandizidwa ndi mawonekedwe a spatial chimafalikira ku fiber yotsika. Pakapangidwe kake, mitundu yonse yomwe ili ndi mzere womwewo umathandizidwa ngati gawo la malo ogawika (sdm) Mu mdm, zopinga zosiyanasiyana (ndiye kuti, mawonekedwe osiyanasiyana) a dongosolo amapatsidwa njira zosiyanasiyana. Mwachitsanzo, njira yomwe imatumizidwa pamwamba pamtengo wa laser yomwe imawoneka ngati makona atatu, lalikulu, kapena bwalo. Maonekedwe omwe amagwiritsidwa ntchito ndi MDM m'mitundu yeniyeni ndi yovuta kwambiri ndipo imakhala ndi machitidwe apadera komanso mawonekedwe. Tekinolojeyi ndi yodabwitsa kwambiri yomwe imasinthiratu kwambiri kufala kwa dambo wa fiber kuyambira 1980s. Tekinoloje ya MDM imapereka njira yatsopano yogwiritsira ntchito njira zambiri ndikuwonjezera kulumikizana ndi kunyamula umodzi wogwiritsira ntchito. Orbital angular funguum (Oam) ndi mawonekedwe akuthupi a mafunde a elekitomic momwe njira yofalitsira imatsimikiziridwa ndi gawo lamphamvu kwambiri. Popeza izi zitha kugwiritsidwa ntchito kukhazikitsa njira zingapo zolekanitsa, zopanda zingwe zam'madzi pang'ono (Oam) zimatha kuwonjezera kuchuluka kwa kufalikira kwa-pointer-to-zingwe kapena kutsogolo).
