Iyini i-GBIC?
I-GBIC iyisifinyezo se-Giga Bitrate Interface Converter, okuwumshini wokusebenzisana wokuguqula amasignali kagesi wegigabit abe amasignali abonakalayo.I-GBIC ingadizayinelwa ukushintshaniswa okushisayo.I-GBIC iwumkhiqizo oshintshashintshayo ohlangabezana nezindinganiso zamazwe ngamazwe.Amaswishi e-Gigabit aklanywe asebenzisa isixhumi esibonakalayo se-GBIC isabelo semakethe esikhulu emakethe ngenxa yokushintshashintsha okuvumelana nezimo.
Yini i-SFP?
I-SFP isifinyezo se-SMALL FORM PLUGGABLE, esingaqondakala kalula njengenguqulo ethuthukisiwe yamamojula we-GBIC.SFP awuhhafu wosayizi wamamojula we-GBIC futhi angacushwa ngenani lezimbobo ezingaphezu kokuphindwe kabili kuphaneli efanayo.Eminye imisebenzi yemojula ye-SFP ngokuyisisekelo iyafana ne-GBIC.Abanye abakhiqizi bokushintsha babiza imojuli ye-SFP ngokuthi i-GBIC miniaturized (MINI-GBIC).Amamojula optical wesikhathi esizayo kufanele asekele ukuxhuma okushisayo, okusho ukuthi angaxhunywa noma anqanyulwe kumadivayisi ngaphandle kokunqanyulwa. amandla.Ngenxa yokuthi i-optical module iyashisa, abaphathi benethiwekhi bangathuthukisa futhi banwebe isistimu ngaphandle kokuvala inethiwekhi, kube nomthelela omncane kubasebenzisi be-inthanethi.I-Hotplug iphinde yenza kube lula ukugcinwa okuphelele futhi ivumela abasebenzisi bokugcina ukuphatha kangcono amamojula wabo we-transceiver. Ngesikhathi esifanayo, ngenxa yalokhu kusebenza kokushintshana kokushisa, imojula inika amandla abaphathi benethiwekhi ukuthi bahlele izindleko eziphelele zokudlulisela nokudlulisa, amabanga okuxhumanisa, nawo wonke ama-topology enethiwekhi.ngokwezidingo zokuthuthukiswa kwenethiwekhi, ngaphandle kokuthi kushintshwe wonke amabhodi esistimu.Amamojula optical asekela lokhu kuxhuma okushisayo okwamanje ane-GBIC ne-SFP, ngoba ubukhulu be-SFP ne-SFF bucishe bufane, bungakwazi ukufakwa ngokuqondile ibhodi lesifunda, eligcina isikhala nesikhathi ekupakishweni, futhi linezinhlobonhlobo zezinhlelo zokusebenza.Ngakho-ke, ukuthuthukiswa kwayo kwesikhathi esizayo kufanelekile ukulindela futhi kungase kusongela ngisho nemakethe ye-SFF.
Yini i-SFF?
I-SFF(Small Form Factor) compact optical module isebenzisa ubuchwepheshe obunembayo obusezingeni eliphezulu bokubonwayo kanye nokuhlanganiswa kwesekethe futhi iyingxenye kuphela yosayizi wemodule ejwayelekile ye-duplex SC(1X9) fiber optic transceiver.Ingakwazi kabili inani lamachweba okubona endaweni efanayo, ukhuphule ukuminyana kwembobo yolayini futhi unciphise izindleko zesistimu ngembobo ngayinye. Ngaphezu kwalokho, imojula yephakheji encane ye-SFF isebenzisa isixhumi esibonakalayo se-kt-rj esifana nenethiwekhi yocingo lwethusi, usayizi ofanayo nesixhumi esibonakalayo sentambo yethusi evamile yenethiwekhi yekhompiyutha, esiza ukuguqulwa kwezinto ezikhona zenethiwekhi esekwe kwikhebula le-copper ukuya kunethiwekhi ye-fiber optical yezinga eliphezulu ukuhlangabezana nokukhula okusheshayo kwesidingo somkhawulokudonsa wenethiwekhi.
Uhlobo lwedivayisi yokuxhumeka kwenethiwekhi
Isixhumi esibonakalayo se-BNC
Isixhumi esibonakalayo se-BNC sibhekisela esibonakalayo sekhebula le-coaxial.I-interface ye-BNC isetshenziselwa ukuxhumeka kwekhebula lama-euro angama-75, ukuhlinzeka ngeziteshi ezimbili zokwamukela (RX) nokuthumela (TX), futhi isetshenziselwa ukuxhuma amasignali angalingani.
I-Optical fiber interface
I-Fiber optic interface iwukusebenza okubonakalayo okusetshenziselwa ukuxhuma izintambo ze-fiber optic.Kuvamise ukuba ne-SC, ST, LC, FC kanye nezinye izinhlobo.Ngoxhumano lwe-10base-f, isixhumi ngokuvamile siwuhlobo lwe-ST, kanti esinye isiphetho se-FC. ixhunywe ku-fiber optic cable rack.FC isifinyezo se-FerruleConnector.Ukuqiniswa kwayo kwangaphandle umkhono wensimbi futhi ukuqiniswa kuyi-screw buckle.ST interface ngokuvamile isetshenziselwa isixhumi esibonakalayo se-10base-f.SC ngokuvamile sisetshenziselwa i-100base-fx kanye ne-GBIC.LC ivame ukusetshenziselwa i-SFP.
I-interface ye-RJ-45
I-interface ye-rj-45 iyisixhumi esibonakalayo se-Ethernet esisetshenziswa kakhulu.I-Rj-45 yigama elivamile lamajekhi asetshenziswayo noma amapulaki anezindawo ezingu-8 (amaphini angu-8) njengoba kuchazwe indinganiso yesixhumi samazwe ngamazwe, esimiswe yi-IEC(60)603-7.
RS – 232 interface
I-interface ye-Rs-232-c (ebuye yaziwe ngokuthi i-EIA rs-232-c) iyindlela esetshenziswa kakhulu yokuxhumana ye-serial. Yasungulwa ngo-1970 yinhlangano yemboni yezogesi yaseMelika (EIA) ngokubambisana nezinhlelo zensimbi, abakhiqizi bemodemu kanye nekhompyutha. abakhiqizi bamatheminali bezilinganiso zokuxhumana ze-serial.Igama layo eligcwele ”izinga lobuchwepheshe le-serial kanambambili yokushintshisana kwedatha phakathi kwemishini yedatha terminal (DTE) kanye namadivayisi zokuxhumana ngedatha (DCE)”.Izinga licacisa ukusetshenziswa kwesixhumi se-DB25 samaphini angama-25, sicacisa. okuqukethwe kwesignali yephinikhodi ngayinye yesixhumi kanye nezinga lamasignali ahlukahlukene.
I-interface ye-RJ-11
I-interface ye-RJ-11 yilokho esikubiza ngokuthi i-interface yolayini wefoni.I-RJ-11 igama elijwayelekile lesixhumi esakhiwe yi-Western Electric.Umumo waso uchazwa njengesixhumi samaphini angu-6.Umumo waso uchazwa njengesixhumi samaphini angu-6. .Phambilini eyayaziwa ngokuthi i-WExW, u-x lapha umele "okusebenzayo", ukuthintana noma umjovo inaliti.Isibonelo, i-WE6W inabo bonke othintana nabo abayisithupha, izinombolo 1 ukuya ku-6, isixhumi esibonakalayo se-WE4W SEBENZISA ophini abangu-4 kuphela, oxhumana nabo ababili abangaphandle kakhulu (1 kanye no-6) ungasebenzisi, i-WE2W ISEBENZISA kuphela izikhonkwane ezimbili ezimaphakathi (okungukuthi, isixhumi esibonakalayo somugqa wefoni).
I-CWDM ne-DWDM
Ngokukhula okusheshayo kwesevisi yedatha ye-inthanethi ye-IP, isidingo somugqa wokudlulisa umkhawulokudonsa siyakhula.Nakuba ubuchwepheshe be-DWDM(dense wavelength division multiplexing) buyindlela ephumelela kakhulu yokuxazulula ukunwetshwa komkhawulokudonsa womugqa, ubuchwepheshe be-CWDM (i-coarse wavelength division multiplexing) bunezinzuzo ngaphezu kwalokho. I-DWDM kuzindleko zesistimu, ukugcinwa kanye nezinye izici.
I-CWDM ne-DWDM zombili ubuchwepheshe bokuhlukanisa i-wavelength multiplexing, obungakwazi ukuhlanganisa ukukhanya kwamaza ahlukene kube yifayibha ewumongo owodwa futhi iwadlulisele ndawonye.ukungakwazi kanye nezinye izici.
Izinga lakamuva le-ITU le-CWDM ngu-g.695, elihlinzeka ngamashaneli e-wavelength angu-18 ngesikhawu esingu-20nm ukusuka ku-1271nm kuya ku-1611nm.Uma kucatshangelwa ithonya lokuphakama kwamanzi kwe-g evamile.I-fibre engu-652, iziteshi ezingu-16 zivame ukusetshenziswa.Ngenxa yesikhala esikhulu sesiteshi, izihlukanisi zamagagasi ezihlanganisiwe nama-lasers ishibhile kunamadivayisi e-DWDM.
Izikhathi zesiteshi se-DWDM ziyi-0.4nm, 0.8nm, 1.6nm nezinye izikhawu ezihlukene njengoba kudingekile, ezincane futhi ezidinga amadivayisi engeziwe okulawula ubude begagasi.Ngakho-ke, amadivaysi asekelwe kubuchwepheshe be-DWDM abiza kakhulu kunalawo asekelwe kubuchwepheshe be-CWDM.
I-PIN photodiode iyisendlalelo sezinto zohlobo lwe-n-doped kancane, olwaziwa ngokuthi isendlalelo se-I(Intrinsic), phakathi kohlobo lwe-p olune-doped kakhulu kanye nama-semiconductors ohlobo lwe-n.Ngenxa yokuthi i-doped kancane, ukugxila kwe-electron kuphansi kakhulu.Ngemva kokusabalalisa, ungqimba olubanzi kakhulu lokuwohloka luyakhiwa, olungathuthukisa isivinini salo sokuphendula nokusebenza kahle kokuguqulwa.I-APD iyi-photodiode enenzuzo.Uma ukuzwela kwesitholi sokubonwayo kuphakeme, i-APD iyasiza ukunweba ibanga lokudlulisela lesistimu.
