Iimodyuli zamehlo, njengezona nxalenye eziphambili zeenkqubo zokunxibelelana kwe-optical, zinoxanduva lokuguqula izibonakaliso zombane kwiimpawu ze-optical kunye nokuzithumela kumgama omde kunye nesantya esiphezulu nge-fiber optical.Ukusebenza kweemodyuli ze-optical kuchaphazela ngokuthe ngqo ukuzinza kunye nokuthembeka kwayo yonke inkqubo yonxibelelwano ye-optical.Ke ngoko, kubalulekile ukuqonda izikhombisi eziphambili zokusebenza kweemodyuli ze-optical.Eli nqaku liza kwazisa izibonakaliso eziphambili zokusebenza kweemodyuli ze-optical ngokweenkcukacha kwiinkalo ezininzi.
1. Izinga losulelo
Isantya sothumelo sesinye sezona zibonakaliso zokusebenza ezisisiseko zemodyuli ye-optical.Imisela inani leebhithi ezinokuhanjiswa yimodyuli ye-optical ngesekhondi.Amazinga okutshintshela aqhele ukulinganiswa ngeMbps (Megabits ngesekhondi) okanye Gbps (Gigabits ngesekhondi).Ukuphakama kwezinga lokudlulisa, amandla okuhanjiswa kwemodyuli ye-optical, enokuxhasa i-bandwidth ephezulu yedatha kunye nokuhanjiswa kwedatha ngokukhawuleza.
2. Amandla akhanyayo kunye nokufumana ubuntununtunu
Amandla akhanyayo abhekiselele ekukhanyeni kokukhanya ekupheleni kokudlulisa imodyuli ye-optical, ngelixa uvakalelo olufumanayo lubhekiselele kukukhanya okuncinci okunokuthi kubonwe yimodyuli ye-optical.Amandla akhanyayo kunye nokufumana uvakalelo zizinto eziphambili kumgama wokuhanjiswa kweemodyuli ze-optical.Ukuphakama kwamandla okukhanya, ukude umqondiso we-optical unokudluliselwa kwi-fiber optical;kwaye ukuphakama kokufumana uvakalelo, imodyuli ye-optical inokubona iimpawu ezibuthathaka ezingabonakaliyo, ngaloo ndlela iphucula amandla okuchasana nokuphazamiseka kwenkqubo.
3. Ububanzi beSpectral
Ububanzi be-Spectral bubhekiselele kuluhlu lwe-wavelength yesignali ye-optical ekhutshwe yimodyuli ye-optical.Ukunciphisa ububanzi be-spectral, uzinzile ngakumbi ukuhanjiswa kweempawu ze-optical fibers kunye nokuxhathisa ngakumbi kwimiphumo yokusabalalisa kunye nokunciphisa.Ngoko ke, ububanzi be-spectral sinye sezibonakaliso ezibalulekileyo zokulinganisa ukusebenza kweemodyuli ze-optical.
4. Ukufota
I-Photostability ibhekisela ekuzinzeni kwamandla akhanyayo kunye neempawu ze-spectral zemodyuli ye-optical ngexesha lokusebenza kwexesha elide.Okungcono ukuzinza kokukhanya, encinci i-attenuation yokusebenza kwemodyuli ye-optical, kwaye iphezulu ukuthembeka kwenkqubo.I-Photostability yenye yezibonakaliso ezibalulekileyo zokulinganisa umgangatho weemodyuli ze-optical.
5. Iimpawu zobushushu
Iimpawu zokushisa zibhekisela ekusebenzeni kweemodyuli ze-optical kumaqondo okushisa ahlukeneyo.Ububanzi beqondo lokushisa lokusebenza kwemodyuli ye-optical, inamandla amandla ayo okuziqhelanisa nokutshintsha kweqondo lokushisa, kunye nokuphakama kozinzo lwenkqubo.Ngoko ke, iimpawu zeqondo lokushisa ngenye yezibonakaliso ezibalulekileyo zokulinganisa ukusebenza kweemodyuli ze-optical.
6. Ukusetyenziswa kwamandla kunye nokusebenza kokutshatyalaliswa kobushushu
Ukusetyenziswa kwamandla kubhekisela kumandla ombane asetyenziswe yimodyuli ye-optical ngexesha lokusebenza, ngelixa ukusebenza kokutshatyalaliswa kobushushu kubhekisela kumandla emodyuli ye-optical yokuchitha ukushisa okuveliswayo.Ukunciphisa ukusetyenziswa kwamandla, ukuphakama kokusetyenziswa kwamandla kwimodyuli ye-optical kunye nokuncinci ukusetyenziswa kwamandla kwenkqubo;kwaye ngcono ukusebenza kokutshatyalaliswa kobushushu, ukuphakama kozinzo lwemodyuli ye-optical kwiindawo eziphezulu zokushisa.
Isishwankathelo, izibonakaliso zentsebenzo eziphambili zeemodyuli ze-optical zibandakanya izinga lokudluliselwa, amandla akhanyayo kunye nokufumana i-sensitivity, ububanzi be-spectral, ukuzinza kokukhanya, iimpawu zeqondo lokushisa, ukusetyenziswa kwamandla kunye nokusebenza kokutshatyalaliswa kobushushu, njl. imodyuli.Xa ukhetha iimodyuli ze-optical, ezi zikhombisi kufuneka ziqwalaselwe ngokubanzi ngokusekelwe kwiimfuno zangempela zokuqinisekisa ukuzinza nokuthembeka kwenkqubo.
