Isandulelo:
Ngokuthuthuka kwesayensi nobuchwepheshe, isivinini sokwaziswa kwasemadolobheni siyakhula, futhi izidingo zobuchwepheshe bezokuxhumana ziya ngokuya ziba phezulu.Imicu ye-Optical isiye yathandwa kakhulu ekuxhumaneni ngenxa yezinzuzo zayo zejubane lokudlulisa ngokushesha, ibanga elide, ukuphepha nokuzinza, ukulwa nokuphazanyiswa, nokwandisa okulula.Inketho yokuqala lapho ubeka.Sivame ukubona ukuthi izidingo zokudluliswa kwedatha yebanga elide ekwakheni amaphrojekthi ahlakaniphile ngokuyisisekelo zisebenzisa i-optical fiber transmission.Isixhumanisi phakathi kwalokhu sidinga amamojula optical kanye ne-fiber optic transceivers.Abasebenzisi abaningi banokungabaza okuthile mayelana nokusetshenziswa kwamamojula optical kanye ne-fiber optic transceivers.Kufanele kuxhunywe kanjani okubili?Yiziphi izinyathelo zokuphepha?
Ake siqale siqonde umehluko phakathi kwalokhu okubili:
1.I-optical module iyimojuli esebenzayo, noma isisekeli, isisetshenziswa esingenakwenziwa esingeke sisetshenziswe sodwa.Isetshenziswa kuphela ekushintsheni nakumadivayisi anezikhala zemojuli ye-optical;ama-transceivers e-fiber optical angamadivayisi asebenzayo futhi ahlukene asebenzayo Imishini ingasetshenziswa yodwa ngokunikezwa kwamandla;
I-2.I-module ye-optical ngokwayo ingenza inethiwekhi ibe lula futhi inciphise iphuzu lokuhluleka, futhi ukusetshenziswa kwama-transceivers optical fiber kuzokwandisa 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 ngokuqhathaniswa, futhi kuyoba nzima kakhulu ukushintshwa nokuthuthukiswa kwe-module optical;
Amamojula we-4.Optical abiza kakhulu kunama-transceivers optical fiber, kodwa azinzile futhi akulula ukuwalimaza;ama-transceivers e-fiber optical ayonga futhi ayasebenza, kodwa izici eziningi ezifana nama-adaptha amandla, isimo se-fiber, kanye nesimo sekhebula lenethiwekhi kufanele kucatshangelwe, futhi ama-akhawunti wokulahlekelwa kokudluliselwa cishe ku-30%;
Amamojula we-5.Optical asetshenziselwa ikakhulukazi ukuxhumana okubonakalayo kwemishini yokuxhumana yenethiwekhi ye-optical efana nokushintsha kokuhlanganisa, ama-core routers, i-DSLAM, i-OLT nezinye izinto zokusebenza, njengalezi: ividiyo yekhompiyutha, ukuxhumana kwedatha, ukuxhumana kwezwi okungenantambo kanye nomunye umgogodla wenethiwekhi ye-fiber optical;ama-transceiver e-fiber optical asetshenziswa ku-Ethernet Endaweni yenethiwekhi yangempela lapho ikhebula lenethiwekhi ingakwazi ukumbozwa khona futhi i-fiber kufanele isetshenziselwe ukunweba ibanga lokudlulisela, ngokuvamile itholakala ekusetshenzisweni kongqimba lokufinyelela lwenethiwekhi yendawo ye-broadband, njenge: high- incazelo yokuhanjiswa kwesithombe sevidiyo yokuqapha ubunjiniyela bezokuphepha kanye nokuxhunywa komugqa wokugcina wekhilomitha wefayibha kumanethiwekhi ezindawo zedolobha elikhulu kanye namanethiwekhi asezingeni eliphezulu;
Ukwengeza, naka amaphuzu amaningana lapho uxhuma i-fiber optical module kanye ne-optical fiber transceiver: ubude be-wavelength kanye nebanga lokudlulisela kufanele kufane, isibonelo, ubude be-waveleng yi-1310nm noma i-850nm ngesikhathi esifanayo, ibanga lokudlulisela liyi-10km. ;i-fiber jumper noma i-pigtail kufanele ibe isixhumi esibonakalayo esifanayo ukuze kuxhunywe Ngokuvamile, imbobo ye-SC esetshenziswa i-optical fibre transceiver kanye nembobo ye-LC isetshenziswa imojula yokubona.Leli phuzu lizovumela ukukhetha kohlobo lwesixhumi esibonakalayo lapho uthenga.Ngesikhathi esifanayo, izinga le-transceiver ye-fiber optical kanye ne-module optical kumele kube okufanayo.Isibonelo, i-Gigabit transceiver ihambisana ne-1.25G optical module, 100M kuya ku-100M, kanye ne-Gigabit kuya ku-Gigabit;uhlobo lwefiber optical yemojula ye-optical kumele lufane, ifayibha eyodwa ibe yifayibha eyodwa Ifayibha ekabili kuya kwemicu emibili.
