Idivayisi ye-CWDM
Incazelo Yomkhiqizo
I-CWDM-55 iyidivayisi engu-1550nm CWDM mux noma yedemux enesihlungi esakhelwe ngaphakathi esingu-1550nm esengeza isignali engu-1550nm ku-com port noma yehlisa isignali engu-1550nm ukusuka ku-com port. Idivayisi yochungechunge lwe-CWDM-xx ilungele ukwengeza noma ukulahla isiteshi se-xx CWDM ohlelweni lwe-fiber optic. Ibanga le-wavelength elijwayelekile le-CWDM lisuka ku-1270nm, 1290nm, 1310nm, 1330nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1410nm, 1450nm, 7nm I-1530nm, 1550nm, 1570nm, 1590nm kuya ku-1610nm, lapho i-1310nm ne-1490nm kuyi-GPON izindlela ezimbili zamaza optical optical for fibre ekhaya, i-1550nm iwubude obujwayelekile bokusakaza bokuqukethwe ngokusetshenziswa kwe-optical fibre amplifier. Idivayisi evamile ye-Nch CWDM mux noma i-de-mux iyisitaki sedivayisi yokuhlunga ye-N-1 ye-CWDM ye-cascading eyodwa.
Ukuxhumana kwe-Fiber optic kushintshe le planethi kusukela ngo-1980s. I-fiber yemodi eyodwa inezinzuzo zokuyilungisa kalula, ukunciphisa kancane, ububanzi be-wavelength optical kanye nedatha yesivinini esiphezulu kubude begagasi obubonakalayo ngakunye. Ngaphezu kwalokho, i-fiber inokuzinza okuphezulu ekushintsheni kwezinga lokushisa kanye nezindawo ezihlukahlukene. I-Fiber optic communications idlala indima ebalulekile kusukela ekushintshisaneni kolwazi lwe-intercontinental kuya kwezokuzijabulisa zomndeni. Amadivaysi e-WDM, ama-Fiber splitters nama-fiber patchcords ayizici ezibalulekile kunethiwekhi ye-passive optical network (PON), esekela amaza amaza okukhanya amaningi asebenza ngokubambisana ukusuka kwelinye iphuzu ukuya kumaphoyinti amaningi izinhlelo zokusebenza zezindlela ezimbili. Ngokuhambisana nokuqanjwa kwezinto ezisetshenziswayo ezifana ne-laser, i-photodiode, i-APD ne-optical amplifier, izingxenye ze-passive fibre optic zenza ikhebula le-fiber litholakale emnyango wekhaya lababhalisile ngezindleko ezithengekayo. I-inthanethi enesivinini esikhulu, ukusakazwa okukhulu kwevidiyo ye-HD ngefayibha kwenza le planethi ibe mncane.
Idivayisi ye-CWDM ingasetshenziswa njengedivayisi ezimele noma ishumekwe ku-laser ne-photodiode. Iphakheji ethandwayo yi-fiber pigtail tube emithathu, ibhokisi lepulasitiki lekhasethi, izindlu ze-LGX kanye ne-chassis engu-19” 1RU.
