Imodyuli ye-optical yenziwe ngezixhobo ze-optoelectronic, iisekethe ezisebenzayo, kunye ne-optical interfaces. Izixhobo ze-Optoelectronic ziquka iinxalenye ezimbini: ukuhambisa kunye nokwamkela. Imodyuli ye-optical inokuguqula isignali yombane kwi-signal optical ekupheleni kokudlulisa ngokuguqulwa kwe-photoelectric, kwaye emva koko idlulisele nge-fiber optical, kwaye emva koko iguqule isignali ye-optical ibe ngumqondiso wombane ekupheleni kokufumana. Nayiphi na imodyuli ye-optical inemisebenzi emibini yokudlulisa kunye nokufumana, kwaye yenza ukuguqulwa kwe-photoelectric kunye nokuguqulwa kwe-electro-optical. Ngale ndlela, imodyuli ye-optical ayinakuhlukaniswa kwizixhobo kuzo zombini iziphelo zenethiwekhi. Kuhlala kukho amashumi amawaka ezixhobo kwiziko ledatha. Ukuqonda ukudityaniswa kwezi zixhobo, iimodyuli ze-optical ziyimfuneko. Namhlanje, iimodyuli ze-optical ziye zaba yinxalenye yemarike kumaziko edatha.
Ukukhethwa kweemodyuli zamehlo
Ngokwandiswa kweemodyuli ze-optical, abathengi abaninzi ngakumbi bahlawula ingqalelo kwiimpawu zokuzinza kunye nokuthembeka kweemodyuli ngokwabo. Kukho iintlobo ezintathu zeemodyuli ze-optical ezithandwayo kwiimarike: iimodyuli zangaphambili zamehlo, iimodyuli ze-optical ezisetyenzisiweyo, kunye neemodyuli ezibonakalayo ezihambelanayo. Njengoko sonke siyazi, ixabiso lemodyuli ye-original optical liphezulu kakhulu, abaninzi abavelisi banokuhlala kude. Ngokubhekiselele kwiimodyuli ze-second-hand optical, nangona ixabiso liphantsi, umgangatho awuqinisekiswanga, kwaye ukulahleka kwepakethi kudla ngokuvela emva kwesiqingatha sonyaka wokusetyenziswa. Ngoko ke, abaninzi abavelisi baye bajika ingqalelo kwiimodyuli ezihambelanayo ze-optical. Enyanisweni, imodyuli ye-optical ehambelanayo inokusebenza okufanayo njengemodyuli ye-optical yasekuqaleni esetyenziswayo, kwaye amaxesha amaninzi aphantsi kunemodyuli ye-optical yasekuqaleni, yiyo loo nto imodyuli ye-optical ehambelanayo inokutshisa. Nangona kunjalo, iimpahla kwiimarike azifani, kwaye abathengisi abaninzi banentlawulo efanelekileyo kunye neentlanzi ezixubileyo, ezibangele ubunzima obuthile ekukhetheni iimodyuli ze-optical. Oku kulandelayo yingxoxo ecacileyo yokukhethwa kweemodyuli ze-optical.
Okokuqala, sahlula njani phakathi kweemodyuli ezintsha ze-optical kunye neemodyuli ze-optical second hand? Sikhankanye ngasentla ukuba iimodyuli ze-second-hand-optical modules zivame ukulahlekelwa iipakethi emva kwesiqingatha sonyaka wokusetyenziswa, okubangelwa amandla optical angazinzanga kunye nokunciphisa i-optical sensitivity. Ukuba sinawo imitha yamandla okukhanya, sinokuyikhupha kwaye siyivavanye ukuze sibone ukuba amandla ayo okukhanya ahambelana neeparitha kwiphepha ledatha. Ukuba ufikelelo lukhulu kakhulu, yimodyuli esetyenziswayo yokubona.
Emva koko jonga ukusetyenziswa kwemodyuli ye-optical emva kokuthengisa. Ubomi benkonzo yemodyuli eqhelekileyo ye-optical yiminyaka emi-5. Ngomnyaka wokuqala, kunzima ukubona umgangatho wemodyuli ye-optical, kodwa inokubonwa kunyaka wesibini okanye wesithathu wokusetyenziswa kwayo.
Okwesibini, jonga ukuhambelana phakathi kwemodyuli ye-optical kunye nesixhobo. Phambi kokuthenga, abathengi kufuneka banxibelelane nomthengisi kwaye babaxelele ukuba loluphi uhlobo lwesixhobo ekufuneka basisebenzise.
Ekugqibeleni, kufuneka sijonge ukuguquguquka kobushushu bemodyuli ye-optical. Ubushushu bemodyuli ye-optical ngokwayo ayiphezulu ngexesha lokusebenza, kodwa indawo yayo yokusebenza ngokubanzi ikwigumbi lekhompyuter okanye kwikhompyuter.tshintsha. Ukuba iqondo lokushisa liphezulu kakhulu okanye liphantsi kakhulu, liya kuchaphazela amandla ayo optical kunye novelwano lwamehlo. Ngokuqhelekileyo, uluhlu lobushushu lwemodyuli ye-optical esetyenzisiweyo yi-0 ~ 70 ° C. Ukuba kwindawo ebanda kakhulu okanye eshushu kakhulu, i-industrial -ibakala -40 ~ 85 ° C imodyuli ebonakalayo iyafuneka.
Ukusetyenziswa kweemodyuli zamehlo
Ukuba ufumanisa ukuba umsebenzi wemodyuli ye-optical uyasilela ngexesha lokusetyenziswa, ungakhathazeki kuqala, kufuneka uhlolisise ngononophelo kwaye uhlalutye unobangela othile. Kukho ubukhulu becala iintlobo ezimbini zokungaphumeleli kokusebenza kweemodyuli ze-optical, oko kukuthi ukungaphumeleli kokuphela kokudlulisa kunye nokungaphumeleli kokuphela kokufumana. Ezona zizathu zixhaphakileyo zezi zilandelayo:
I-port ye-optical port yemodyuli ye-optical ibonakaliswe kwimeko-bume. Izibuko lamehlo lingcoliswe luthuli.
Ubuso besiphelo somdibaniso wefiber optical osetyenzisiweyo bungcolisekile, kwaye i-port optical yemodyuli ye-optical ingcolisekile kabini.
Ubuso besiphelo somdibaniso we-optical kunye ne-pigtail abusetyenziswanga ngokufanelekileyo, kwaye ubuso bokugqibela buhlanjululwe;
Sebenzisa izihlanganisi zefiber optic ezisezantsi.
Ngoko ke, emva kokuthenga imodyuli ye-optical ngokuqhelekileyo, nikela ingqalelo ekucoceni nasekukhuseleni imodyuli ye-optical ekusebenziseni ngokuqhelekileyo. Emva kokuyisebenzisa ngokuqhelekileyo, kuyacetyiswa ukuba ubeke iplagi yothuli xa ingasetyenziswa. Kuba ukuba umfowunelwa wamehlo akacocekanga, unokuchaphazela umgangatho womqondiso, onokubangela iingxaki ze-LINK kunye neengxaki ze-bit error.
