Izazinzulu ezivela kwihlabathi liphela ziphucule ngempumelelo ukusebenza kwee-erbium-doped fiber amplifiers (ii-EDFA), zenza inkqubela phambili enkulu kwicandelo lonxibelelwano lwe-optical.I-EDFAsisixhobo esibalulekileyo sokuphucula amandla emiqondiso ye-optical kwi-optical fibers, kwaye ukuphuculwa kokusebenza kwayo kulindeleke ukuba kuphucule kakhulu amandla eenkqubo zonxibelelwano lwe-optical.
Unxibelelwano lwe-optical, oluxhomekeke ekudlulisweni kwemiqondiso yokukhanya ngeefayibha ze-optical, luye lwaguqula iinkqubo zonxibelelwano zanamhlanje ngokubonelela ngokudluliselwa kwedatha okukhawulezayo nokuthembekileyo. Ii-EDFA zidlala indima ebalulekileyo kule nkqubo ngokwandisa ezi miqondiso zokukhanya, zonyusa amandla azo kwaye ziqinisekise ukudluliselwa okusebenzayo kumgama omde. Nangona kunjalo, ukusebenza kwee-EDFA bekusoloko kulinganiselwe, kwaye izazinzulu bezisebenza nzima ukuphucula amandla azo.
Impumelelo yamva nje ivela kwiqela lezazinzulu eziphucule ngempumelelo ukusebenza kwee-EDFA ukuze zonyuse kakhulu amandla esignali ye-optical. Le mpumelelo kulindeleke ukuba ibe nefuthe elikhulu kwiinkqubo zonxibelelwano lwe-optical, inyuse ukusebenza kwazo kunye namandla azo.
I-EDFA ephuculweyo ivavanywe kakhulu phantsi kweemeko zelebhu kwaye iziphumo zithembisa kakhulu. Izazinzulu zibone ukwanda okukhulu kwamandla esignali ye-optical, idlula imida yangaphambili ye-EDFAs eqhelekileyo. Olu phuhliso luvula amathuba amatsha kwiinkqubo zonxibelelwano lwe-optical, okwenza amazinga okudlulisa idatha akhawulezileyo nathembekileyo.
Ukuqhubela phambili kwiinkqubo zonxibelelwano lwe-optical kuya kunceda amashishini kunye namacandelo ahlukeneyo. Ukusuka kwi-telecom ukuya kwiziko ledatha, ezi EDFA ziphuculweyo ziya kubonelela ngokusebenza okuphuculweyo ukuqinisekisa ukuhanjiswa kwedatha okungenamthungo nokufanelekileyo. Olu phuhliso lubaluleke kakhulu kwixesha lobuchwepheshe be-5G, njengoko imfuno yokuhanjiswa kwedatha okukhawulezayo nomthamo ophezulu iqhubeka nokukhula ngokukhawuleza.
Abaphandi abaphambili kule mpumelelo banconywe ngokuzinikela kwabo kunye nobuchule babo. Isazinzulu esiphambili seqela, uGqr. Sarah Thompson, uchaze ukuba ukuphuculwa kwe-EDFA kufezekiswe ngokudityaniswa kwezixhobo eziphambili kunye noyilo olutsha. Olu dibaniso luzisa amandla akhulisiweyo, nto leyo eguqula ukusebenza kweenkqubo zonxibelelwano lwe-optical.
Iindlela ezinokubakho zokusetyenziswa kolu phuculo zinkulu kakhulu. Akuyi kuphucula kuphela ukusebenza kakuhle kweenkqubo zonxibelelwano lwe-optical ezikhoyo, kodwa kuya kuvula namathuba amatsha ophando nophuhliso kwiinkalo ezinxulumene noko. Amandla aphezulu e-EDFA anokunceda uphuhliso lwetekhnoloji entsha efana neenkqubo zonxibelelwano lwe-optical ezikude, ukusasazwa kwevidiyo okunentsingiselo ephezulu kakhulu, kwanonxibelelwano olukwindawo enzulu.
Nangona olu phuhliso lubalulekile ngokungathandabuzekiyo, uphando olongezelelweyo kunye nophuhliso kusafuneka ngaphambi kokuba i-EDFA ephuculweyo iqaliswe ngomlinganiselo omkhulu. Iinkampani ezaziwayo kumashishini onxibelelwano kunye netekhnoloji zibonakalise umdla wokusebenza namaqela ezenzululwazi ukuphucula itekhnoloji kunye nokuyidibanisa kwiimveliso zabo.
Ukuphuculwa kweI-EDFA luphawu olubalulekileyo kwicandelo lonxibelelwano lwe-optical. Ukwanda kwamandla okukhupha ezi zixhobo kuya kutshintsha ukusebenza kweenkqubo zonxibelelwano lwe-optical, okuvumela ukuhanjiswa kwedatha okukhawulezayo nokuthembekileyo ngakumbi. Njengoko izazinzulu ziqhubeka nokuqhubela phambili imida yetekhnoloji, ikamva lonxibelelwano lwe-optical libonakala liqaqambile kunangaphambili.
