Ngokuthuthuka okuqhubekayo kwemboni yezokuxhumana ye-optical, ubuchwepheshe obusha nezixazululo zokonga ziyaqhubeka nokutholakala.Isibonelo, imikhiqizo ye-CWDM ne-DWDM iya ngokuya isetshenziswa kabanzi, ngakho-ke namuhla sizofunda ngemikhiqizo ye-CWDM ne-DWDM!
I-CWDM ubuchwepheshe bokudlulisa i-WDM obungabizi kakhulu bongqimba lokufinyelela lwenethiwekhi yendawo yedolobha elikhulu.Ilondoloza ngempumelelo izinsiza ze-fiber nezindleko zokuxhumana, ixazulula izinkinga ezimbili zokushoda kwefayibha kanye nokudluliswa okusobala kwezinsizakalo eziningi.Inethiwekhi ingakhiwa futhi ibhizinisi lingenziwa ngesikhathi esifushane.
Izinzuzo ze-CWDM:
※ Inzuzo ebaluleke kakhulu ye-CWDM yizindleko eziphansi zemishini.
※ Inganciphisa izindleko zokusebenza zenethiwekhi.
※ Ingakhuphula kakhulu umthamo wokudlulisela we-fiber optical futhi ithuthukise ukusetshenziswa kwezinsiza ze-fiber optical.
※ Usayizi omncane kanye nokusetshenziswa kwamandla okuphansi.
※ Inokuvumelana nezimo okuhle nokuqina
I-DWDM ingahlanganisa futhi idlulise amaza ahlukene kufibre efanayo ngesikhathi esisodwa.Ukuze isebenze kahle, i-fiber eyodwa iguqulwa ibe imicu eminingi ebonakalayo.I-DWDM ivamise ukuba namafomu amabili okufaka isicelo: i-DWDM evulekile kanye ne-DWDM edidiyelwe.
Izinzuzo ze-DWDM:
※ Iphrothokholi yayo nesivinini sokudlulisa akubalulekile.
※ I-multiplexer kanye ne-splitter yohlelo oludidiyelwe lwe-DWDM kusetshenziswa ngokuhlukene kumthumeli nomamukeli.
※ Imishini ye-DWDM edidiyelwe inesakhiwo esilula nevolumu encane, cishe ingxenye eyodwa kwezinhlanu zesikhala esithathwe i-DWDM evulekile, igcina izinsiza zegumbi lekhompyutha.
※ Uhlelo oludidiyelwe lwe-DWDM lusebenzisa kuphela izingxenye ze-passive (ezifana nama-multiplexer noma ama-demultiplexer) ekugcineni kokwamukela nokudlulisa.Ama-opharetha e-Telecom angafaka ama-oda ngokuqondile avela kubakhiqizi bedivayisi, behlise izixhumanisi zokuhlinzeka nezindleko eziphansi, ngaleyo ndlela bonge izindleko zemishini.
I-CWDM ne-DWDM zombili zingama-wavelength division multiplexers, ngakho-ke yimuphi umehluko phakathi kwazo?I-CWDM (okungukuthi, i-sparse wavelength division multiplexing) ne-DWDM (okungukuthi, ukuphindaphinda kwe-wavelength eminyene), ngokwezwi nezwi singabona umehluko phakathi kwakho kokubili: “okuminyene” kanye “nokuncane”.I-Sparse Wavelength Division Multiplexing, njengoba igama lisho, isihlobo esiseduze se-Dense Wavelength Division Multiplexing.
Ukwehluka kwabo kubonakala ngokuyinhloko kumaphuzu amathathu alandelayo:
1) Isikhala sesiteshi senkampani yenethiwekhi ye-CWDM sibanzi uma kuqhathaniswa, ngakho-ke, amaza amaza okukhanya angama-5 kuya ku-6 kuphela angaphindaphindwa ku-fiber optical efanayo, futhi umehluko phakathi kwamagama "ancane" kanye "naminyene" uvela kulokhu;
2) I-laser eguquliwe ye-CWDM isebenzisa i-laser engapholi, kuyilapho i-DWDM isebenzisa i-laser epholile.I-laser epholile isebenzisa ukulungisa izinga lokushisa, kanti i-laser engapholisiwe isebenzisa ukushuna kwe-electronic.I-CWDM manje isidume kakhulu phakathi kwabahlinzeki bezicelo zebhizinisi jikelele.Kalula nje: I-DWDM iyingxenye ye-CWDM.
3) Indawo esetshenziswayo ihlukile.I-CWDM isetshenziswa kakhulu kusendlalelo sokuhlangana kanye nesendlalelo sokufinyelela;I-DWDM isetshenziswa endaweni yokusebenza yokuxhumana nololiwe.
