Node ea Optical ea SR100-WD FTTH e nang le WDM ke moamoheli o monyenyane oa optical oa ka tlung o se nang phepelo ea motlakase, o etselitsoeng lits'ebetso tsa FTTP/FTTH, haholo-holo bakeng sa thelevishene ea dijithale. Tshebetso e phahameng, matla a optical a moamoheli a tlase, le litšenyehelo tse tlase ke khetho e ntle ka ho fetisisa ea tharollo ea FTTH bakeng sa MSO. WDM e hahiloeng kahare e kopantsoe bakeng sa lets'oao la video la 1550nm le lets'oao la data la 1490nm /1310nm ka har'a faeba e le 'ngoe.
Ponahalo ea 1490nm/1310nm bakeng sa ho hokela sesebelisoa sa ONT. Li loketse haholo sistimi ea PON le TV.
Mochini ona o amohela tube e amohelang ea optical e nang le kutlo e phahameng, ntle le phepelo ea motlakase, 'me ha ho na tšebeliso ea motlakase. Ha boemo ba tlhahiso ea matla a optical bo kenngoa Pin= -1dBm, Vo= 68dBuV, kopanyo ea ts'ebeliso ea moruo, e tenyetsehang, ts'ebeliso ea faeba marangrang a lapeng.
E hahiloe ka hare ho CWDM, e loketse sistimi ea bolelele ba maqhubu a mararo a faeba e le 'ngoe, Wavelength e sebetsang ea CATV ea 1550nm, ea feta bolelele ba maqhubu ba 1310/1490nm, 'me e ka hokahanya ONU ea EPON, GPON habonolo.
Likaroloana
- PON WDM e hahiloeng kahare
- Bandwidth e sebetsang ea 1 GHz
- Liphetho tse 2 tsa RF tse sa khetheheng
- Sebaka se tlase sa optical se kenyeletsang: +1 ~ -15dBm
- Boemo ba tlhahiso ho fihlela ho 61.9 - 64.4dBuV, TV ea Dijithale (Pin= -1dBm)
- Letšoao le ikhethileng le Moralo oa ho Paka lia fumaneha
- Ntle le Phepelo ea Motlakase, 'me HA HO Tšebeliso ea Motlakase
HLOKOMELA
1. Ha o sebedisa sehokelo sa RF, sebopeho sa ho kenya sa RF se tlameha ho tiisetswa ho STB. Ho seng jwalo, mobu o mobe mme o tla baka ho senyeha ha dikarolo tsa maqhubu a phahameng a matshwao a TV ya Dijithale a MER.
2. Boloka sehokelo sa optical se hlwekile, sehokelo se sebe se tla baka boemo ba tlhahiso ya RF bo tlase haholo.
