Ngokuthuthuka kwesayensi nobuchwepheshe, isivinini sokwaziswa kwasemadolobheni siyakhula, futhi izidingo zobuchwepheshe bezokuxhumana ziya ngokuya ziba phezulu. Imicu yamehlo iya ngokuya ithandwa kakhulu ekuxhumaneni ngenxa yezinzuzo zayo zejubane lokudlulisa ngokushesha, ibanga elide, ukuphepha nokuzinza, ukulwa nokugxambukela, nokwanda okulula. Inketho yokuqala lapho ubeka. Sivame ukubona ukuthi izidingo zokudluliselwa kwedatha yebanga elide ekwakheni amaphrojekthi ahlakaniphile ngokuyisisekelo zisebenzisa i-optical fiber transmission. Isixhumanisi phakathi kwalokhu sidinga amamojula optical kanye nama-fiber optic transceivers.
Umehluko phakathi kwe-optical module kanye ne-optical fiber transceiver:
1.I-optical module iyimojuli esebenzayo, noma isisekeli, iyisisetshenziswa esingenzi lutho esingeke sisetshenziswe sodwa. Isetshenziswa kuphela ngaphakathiamaswishikanye namadivayisi anezikhala zemojuli ye-optical; i-optical fibre transceiver iyisisetshenziswa esisebenzayo futhi iyisisetshenziswa esihlukile.
I-2.I-module ye-optical ngokwayo ingenza inethiwekhi ibe lula futhi inciphise iphuzu lokuhluleka, futhi ukusetshenziswa kwama-transceivers optical fiber kuzokwengeza imishini eminingi, kwandise kakhulu izinga lokuhluleka kanye nokuthatha indawo yokugcina yekhabhinethi, engeyona enhle;
I-3.I-module ye-optical isekela ukushintshwa okushisayo, futhi ukucushwa kuvumelana nezimo; i-transceiver ye-fiber optical ilinganiselwe, futhi ukushintshwa nokuthuthukiswa kuyoba nzima kakhulu kunemodyuli ye-optical;
Amamojula we-4.Optical abiza kakhulu kunama-transceivers optical fiber, kodwa azinzile futhi awawonakali kalula; ama-transceiver efiber optical ayonga futhi ayasebenza, kodwa izici eziningi ezifana nama-adaptha amandla, isimo se-fiber, nesimo sekhebula lenethiwekhi kufanele kucatshangelwe. Ukulahleka kokudluliselwa kubalelwa cishe ku-30%;
Ukwengeza, qaphela amaphuzu amaningana lapho uxhuma i-fiber optical module kanye ne-optical fiber transceiver: ubude be-wavelength kanye nebanga lokudlulisela kumele kufane, isibonelo, ubude be-waveleng yi-1310nm noma i-850nm ngesikhathi esifanayo, ibanga lokudlulisela liyi-10km. ; i-fiber jumper noma i-pigtail kufanele ibe isikhombimsebenzisi esifanayo sokuxhuma, Ngokuvamile, i-transceiver ye-fiber optical isebenzisa i-SC port, futhi imodyuli ye-optical isebenzisa ichweba le-LC.Leli phuzu lizokwenza ukuthi kukhethwe uhlobo lwesixhumi esibonakalayo lapho uthenga. Ngesikhathi esifanayo, izinga le-transceiver ye-fiber optical kanye nemodyuli ye-optical kufanele ifane, isibonelo, i-transceiver ye-Gigabit ihambisana ne-module ye-1.25G optical, i-100M kuya ku-100M, ne-Gigabit ku-Gigabit; uhlobo lwe-fiber optical yemojula ye-optical kumele ifane, i-fiber eyodwa ibe yifayibha eyodwa, i-Dual fiber kuya ku-dual fiber.
