Imojula ye-optical yakhiwe ngamadivayisi we-optoelectronic, ama-circuits asebenzayo, kanye ne-optical interfaces. Imishini ye-Optoelectronic ihlanganisa izingxenye ezimbili: ukudlulisa nokwamukela. Imojula ye-optical ingaguqula isignali kagesi ibe isignali yokubona ekugcineni kokudlulisela ngokuguqulwa kwe-photoelectric, bese iyidlulisela nge-fiber optical, bese iguqula isignali ye-optical ibe isignali kagesi ekugcineni kokwamukela. Noma iyiphi imojuli ye-optical inemisebenzi emibili yokudlulisa nokwamukela, futhi yenza ukuguqulwa kwe-photoelectric kanye nokuguqulwa kwe-electro-optical. Ngale ndlela, imojula ye-optical ayikwazi ukuhlukaniswa kumadivayisi kuzo zombili iziphetho zenethiwekhi. Ngokuvamile kukhona amashumi ezinkulungwane zamadivayisi esikhungweni sedatha. Ukuze ubone ukuxhumana kwalawa madivayisi, amamojula abonakalayo abalulekile. Namuhla, amamojula abonakalayo abe ingxenye yemakethe yezikhungo zedatha.
Ukukhethwa kwamamojula optical
Ngokunwetshwa kwamamojula optical, amakhasimende amaningi ngokwengeziwe anaka izici zokuzinza nokuthembeka kwamamojula ngokwawo. Kunezinhlobo ezintathu zamamojula optical adumile emakethe: amamojula optical original, amamojula optical asetshenzisiwe, namamojula optical ahambisanayo. Njengoba sonke sazi, intengo ye-original optical module iphezulu kakhulu, abakhiqizi abaningi bangakwazi ukuhlala kude. Ngokuqondene namamojula we-second-hand optical, nakuba intengo iphansi kakhulu, ikhwalithi ayiqinisekisiwe, futhi ukulahlekelwa kwephakethe kuvame ukuvela ngemva kwesigamu sonyaka wokusetshenziswa. Ngakho-ke, abakhiqizi abaningi baphendule ukunaka kwabo kumamojula ahambisanayo optical. Ngempela, imodyuli ye-optical ehambisanayo inokusebenza cishe okufanayo njengemodyuli yokuqala ye-optical esetshenziswayo, futhi ishibhile izikhathi eziningana kunemodyuli yasekuqaleni ye-optical, yingakho imodyuli ye-optical ehambisanayo ingashisa. Kodwa-ke, izimpahla emakethe azifani, futhi abathengisi abaningi banenkokhelo enhle nezinhlanzi ezixubile, okuye kwabangela ubunzima obuthile ekukhethweni kwamamojula optical. Okulandelayo ingxoxo enemininingwane yokukhethwa kwamamojula optical.
Okokuqala nje, sihlukanisa kanjani phakathi kwamamojula optical amasha namamojula asetshenziswa ngesandla sesibili? Sishilo ngenhla ukuthi amamojula we-second-hand optical avame ukulahlekelwa amaphakethe ngemva kwesigamu sonyaka wokusetshenziswa, okubangelwa amandla optical angazinzile kanye nokunciphisa ukuzwela kwe-optical. Uma sinemitha yamandla okubona, singayikhipha futhi siyihlole ukuze sibone ukuthi amandla ayo okubona ayahambisana yini namapharamitha eshidi ledatha. Uma ukufinyelela kukukhulu kakhulu, kuyimojuli yokubona esetshenzisiwe.
Bese ubheka ukusetshenziswa kwemojuli ye-optical ngemva kokuthengisa. Impilo yesevisi yemojula evamile ye-optical iminyaka emi-5. Ngonyaka wokuqala, kunzima ukubona ikhwalithi ye-module optical, kodwa ingabonakala ngonyaka wesibili noma wesithathu wokusetshenziswa kwayo.
Okwesibili, bheka ukuhambisana phakathi kwemojula ye-optical kanye nedivayisi. Ngaphambi kokuthenga, abathengi badinga ukuxhumana nomphakeli futhi babatshele ukuthi yiluphi uhlobo lwesisetshenziswa okufanele balusebenzise.
Okokugcina, sidinga futhi ukubheka ukuguquguquka kwezinga lokushisa kwemojula ye-optical. Izinga lokushisa lemojula ye-optical ngokwayo aliphezulu ngesikhathi sokusebenza, kodwa indawo yayo yokusebenza evamile isegumbini lekhompyutha nomashintsha. Uma izinga lokushisa liphezulu kakhulu noma liphansi kakhulu, lizophazamisa amandla ayo okubona kanye nokuzwela okubonakalayo. Ngokuvamile, izinga lokushisa lemojula ye-optical esetshenziswayo lingu-0 ~ 70 ° C. Uma lisendaweni ebanda kakhulu noma eshisa kakhulu, imboni -grade -40 ~ 85 ° C module optical liyadingeka.
Ukusetshenziswa kwamamojula optical
Uma uthola ukuthi umsebenzi we-optical module wehluleka ngesikhathi sokusetshenziswa, ungakhathazeki kuqala, kufanele uhlole ngokucophelela futhi uhlaziye imbangela ethile. Kukhona ikakhulukazi izinhlobo ezimbili zokuhluleka kokusebenza kwamamojula optical, okungukuthi ukwehluleka kokuphela kokudlulisa kanye nokwehluleka kokuphela kokuthola. Izizathu ezivame kakhulu yilezi ezilandelayo:
Imbobo yokubona yemojuli ye-optical ivezwa endaweni ezungezile. Imbobo yokubona ingcoliswe uthuli.
Ubuso bokugcina besixhumi se-fiber optical esisetshenzisiwe bungcolile, futhi imbobo yokubona yemojuli ye-optical ingcoliswa kabili.
Ubuso bokuphela kwesixhumi se-optical nge-pigtail abusetshenziswanga kahle, futhi ubuso bokugcina buhlutshiwe;
Sebenzisa izixhumi ze-fiber optic ezingaphansi.
Ngakho-ke, ngemva kokuthenga i-optical module evamile, qaphela ukuhlanza nokuvikelwa kwe-module optical ekusetshenzisweni okuvamile. Ngemuva kokuyisebenzisa ngokujwayelekile, kunconywa ukuthi ubeke ipulaki yothuli uma ingasetshenziswa. Ngoba uma oxhumene naye wamehlo engahlanzekile, kungase kuthinte ikhwalithi yesiginali, engabangela izinkinga ze-LINK kanye nezinkinga zephutha elincane.
