Ngokuthuthuka kokuxhumana kwe-optical, izingxenye zokuxhumana ze-optical nazo zikhula ngokushesha.Njengenye yezingxenye zokuxhumana optical, module optical idlala indima photoelectric ukuguqulwa.Kunezinhlobo eziningi zamamojula optical, ezivamile yi-QSFP28 optical module, i-SFP optical module, i-QSFP + optical module, i-CXP optical module, i-CWDM optical module, i-DWDM optical module nokunye.Imojula ngayinye ye-optical inezimo ezihlukene zohlelo lokusebenza nemisebenzi.Manje ngizokwethula imojula yokubona ye-CWDM.
I-CWDM ubuchwepheshe bokudlulisa i-WDM obungabizi kakhulu bongqimba lokufinyelela lwenethiwekhi yendawo yedolobha elikhulu.Empeleni, i-CWDM iwukusebenzisa i-multiplexer optical to multiplex optical signals of wavelengths ehlukene ibe i-fiber optical eyodwa ukuze idluliselwe.isignali, xhuma kumshini wokwamukela ohambelanayo.
Ngakho-ke, iyini imojula ye-CWDM optical?
I-CWDM optical module iyimojula yokubona esebenzisa ubuchwepheshe be-CWDM, esetshenziselwa ukubona ukuxhumana phakathi kwemishini yenethiwekhi ekhona kanye ne-CWDM multiplexer/demultiplexer.Uma esetshenziswa nama-multiplexers/demultiplexers e-CWDM, amamojula e-CWDM optical angakhuphula umthamo wenethiwekhi ngokudlulisa iziteshi zedatha eziningi ezinamaza okukhanya okuhlukile (1270nm kuya ku-1610nm) ku-fiber eyodwa efanayo.
Yiziphi izinzuzo ze-CWDM?
Inzuzo ebaluleke kakhulu ye-CWDM izindleko eziphansi zemishini.Ngaphezu kwalokho, enye inzuzo ye-CWDM ukuthi inganciphisa izindleko zokusebenza zenethiwekhi.Ngenxa yobukhulu obuncane, ukusetshenziswa kwamandla okuphansi, ukugcinwa kalula kanye nokunikezwa kwamandla okulula kwemishini ye-CWDM, ukunikezwa kwamandla ka-220V AC kungasetshenziswa.Ngenxa yenani elincane lama-wavelengths, amandla okusekela ebhodi mancane.Imishini ye-CWDM esebenzisa amagagasi angu-8 ayinazo izidingo ezikhethekile kuma-optical fibers, futhi i-G.652, G.653, ne-G.655 optical fibers ingasetshenziswa, futhi izintambo ezibonakalayo ezikhona zingasetshenziswa.Uhlelo lwe-CWDM lungakhuphula kakhulu amandla okudlulisela ama-optical fibers futhi luthuthukise ukusetshenziswa kwezinsiza ze-fiber optical.Ukwakhiwa kwenethiwekhi yendawo yedolobha elikhulu kubhekene nezinga elithile lokushoda kwezinsiza ze-fiber optical noma intengo ephezulu yamafiber optical aqashisiwe.Njengamanje, uhlelo olujwayelekile lokuhlukanisa i-wavelength division multiplexing lungahlinzeka ngamashaneli angu-8 optical, futhi lungafinyelela iziteshi ze-optical eziyi-18 ngokwesilinganiso se-G.694.2 se-ITU-T.
Enye inzuzo ye-CWDM ubukhulu bayo obuncane kanye nokusetshenziswa kwamandla okuphansi.Ama-lasers ohlelweni lwe-CWDM awadingi iziqandisi ze-semiconductor nemisebenzi yokulawula izinga lokushisa, ngakho-ke ukusetshenziswa kwamandla kungancishiswa kakhulu.Isibonelo, i-laser ngayinye kusistimu ye-DWDM idla amandla angaba ngu-4W, kuyilapho i-laser ye-CWDM engenawo okupholile idla kuphela u-0.5W wamandla.Imodyuli ye-laser eyenziwe lula ohlelweni lwe-CWDM inciphisa umthamo wemojula ye-transceiver optical edidiyelwe, futhi ukwenziwa lula kwesakhiwo semishini nakho kunciphisa umthamo wemishini futhi kusindisa isikhala ekamelweni lemishini.
Yiziphi izinhlobo zamamojula we-CWDM optical?
(1) CWDM SFP module optical
I-CWDMSFP optical module iyimojula yokubona ehlanganisa ubuchwepheshe be-CWDM.Ngokufanayo ne-SFP evamile, imojula yokubona ye-CWDM SFP iyidivayisi eshintshashintshayo/yokukhiphayo eshintshwayo efakwe embobeni ye-SFP yeswishi noma umzila, futhi ixhunywe kunethiwekhi yefiber optical ngokusebenzisa lesi mbobo.Kuyisixazululo esinomnotho nesisebenzayo soxhumano lwenethiwekhi esisetshenziswa kakhulu ezinhlelweni zenethiwekhi ezifana ne-Gigabit Ethernet ne-Fiber Channel (FC) emakhempasini, ezikhungweni zedatha, kanye namanethiwekhi endawo yedolobha elikhulu.
(2) I-CWDM GBIC (I-Gigabit Interface Converter)
I-GBIC iyidivayisi eshintshashintshayo eshintshashintshayo/yokukhiphayo exhuma embobeni ye-Gigabit Ethernet noma i-slot ukuze iqedele uxhumano lwenethiwekhi.I-GBIC futhi iyindinganiso ye-transceiver, evame ukusetshenziswa ngokuhambisana ne-Gigabit Ethernet kanye ne-Fiber Channel, futhi isetshenziswa kakhulu ekushintsheni kwe-Gigabit Ethernet namarutha.Ukuthuthukiswa okulula okuvela engxenyeni evamile ye-LH, kusetshenziswa amalaza e-DFB anobude obuthile obuthile, kukhuthaza ukuthuthukiswa kwamamojula okusebenza we-CWDM GBIC kanye namamojula okusebenza we-DWDM GBIC.Amamojula we-GBIC optical ngokuvamile asetshenziselwa ukudluliselwa kwe-fiber optical ye-Gigabit Ethernet, kodwa futhi ahilelekile kwezinye izimo, njengokunciphisa isivinini senethiwekhi ye-fiber optical, ukusheshisa kanye nezinhlelo zokusebenza zokudlulisa isilinganiso eziningi ezizungeze i-2.5Gbps.
I-GBIC optical module iyashintshashintsha.Lesi sici, esihlanganiswe nomklamo owenziwe ngomsiki wendlu, senza kube nokwenzeka ukushintsha usuka kolunye uhlobo lwesixhumi esibonakalayo sangaphandle uye kolunye uhlobo lokuxhuma ngokumane ufake i-GBIC optical module.Ngokuvamile, i-GBIC ivamise ukusetshenziswa ngokuhlangana nezixhumi ze-SC interface.
(3) CWDM X2
I-CWDM X2 optical module, esetshenziselwa ukuxhumana kwedatha ye-CWDM optical, njenge-10G Ethernet kanye nezinhlelo zokusebenza ze-Fiber Channel ye-10G.Ubude be-wavelength be-CWDMX2 optical module bungaba ukusuka ku-1270nm ukuya ku-1610nm.Imojula yokubona ye-CWDMX2 ithobelana nezinga le-MSA.Isekela ibanga lokudlulisela elingafika kumakhilomitha angu-80 futhi ixhunywe kuntambo ye-fiber patch ye-duplex SC yemodi eyodwa.
