Lefatšeng la kajeno le potlakileng, moo khokahanyo e bapalang karolo ea bohlokoa karolong e 'ngoe le e 'ngoe ea bophelo ba rona, ho bohlokoa ho ba le litharollo tsa marang-rang tse tšepahalang le tse sebetsang hantle ho fihlela litlhoko tse fapaneng tsa malapa. Ka ho fihla ha mahlale a tsoetseng pele joalo ka CATV ONUs (Optical Network Units), re bona tsoelo-pele e kholo ea khokahanyo ea lapeng. Posong ena ea blog, re tla shebana le lefatše le monate la CATV ONU, bokhoni ba lona, le kamoo le ka fetolang khokahanyo ea lapeng.
E kopantsoe le theknoloji ea dual-fiber three-wave:
CATV ONUe hahiloe holim'a dual-fiber le thekenoloji ea maqhubu a mararo ho netefatsa khokahanyo ea Inthanete e tsitsitseng, e potlakileng. Theknoloji ena e tsoetseng pele e kopanya matla a fiber optics ho fetisetsa melaetsa ea data, lentsoe le video ka nako e le 'ngoe, ho fa basebelisi phihlelo ea inthanete e se nang moeli, e sa sitisoeng.
Komiti ea Khoebo ea Phatlalatso ea Phatlalatso le Thelevishene ea FTTH:
E 'ngoe ea likarolo tse ka sehloohong tsa CATV ONU ke boto ea eona e kopantsoeng ea litšebeletso, e ka kopanyang ntle le seam radio le thelevishene litšebeletso tsa FTTH (fiber to the home). Ka kopanyo ena, basebelisi ba ka natefeloa ke mefuta e fapaneng ea liteishene tsa seea-le-moea le TV ho tsoa boiketlong ba malapa a bona, ba ntlafatsa boiphihlelo ba bona ba boithabiso. Ka ho sebelisa matla a ho amohela optical, CATV ONU e netefatsa kamohelo ea matšoao le phetisetso e se nang sekoli ho feta litharollo tse tloaelehileng tsa koporo.
WiFi e se nang mohala le ts'ebetso ea ho amohela leseli la CATV:
CATV ONU e kopanya bokhoni ba ho amohela WiFi le CATV optical ho feta litharollo tsa setso tsa khokahanyo. Khokahano ena e thusa basebelisi ho theha LAN ea lehae habonolo (Local Area Network). CATV ONU e fana ka likhokahano tse 4 tsa Ethernet le likhokahano tsa WiFi tse se nang mohala, tse lumellang lisebelisoa tse ngata ho hokela le ho arolelana lisebelisoa ka nako e le 'ngoe. Ebang u shebella lifilimi, lipapali tsa marang-rang, kapa u sebetsa u le hae, LAN ea lapeng e entsoeng ke CATV ONU e thusa ho hokahanya le ho arolelana boitsebiso ka lapeng.
Ts'ehetsa lits'ebeletso tsa TV tsa Marang-rang le tsa cable le thelevishene:
Ka CATV ONU, basebelisi ba ke ke ba natefeloa ke lits'ebeletso tsa Marang-rang feela, empa hape ba khona ho fihlella khaso e kholo ea CATV le litaba tsa thelevishene. Ka ho sebelisa sebopeho sa Ethernet le WiFi e se nang mohala, CATV ONU e nolofalletsa basebelisi ho sheba Marang-rang ka lebelo la lehalima ho feta EPON (Ethernet Passive Optical Network). Ka nako e ts'oanang, CATV optical receiver e fumana lipontšo tsa TV tsa digital ho etsa bonnete ba hore basebelisi ba fumana phihlelo ea boleng bo phahameng, e phahameng ea tlhaloso ea TV. Khokahano ea lits'ebeletso tsa TV tsa Marang-rang le tsa cable e hlile e hlokomela pono ea fiber-to-the-hae (FTTH), e fa basebelisi tharollo e felletseng ea khokahanyo.
Ka kakaretso:
Ka bokhutšoane,CATV ONUthekenoloji e fetotse ka ho feletseng likhokahano tsa lapeng ka ho kopanya theknoloji ea li-dual-fiber le maqhubu a mararo, liboto tse kopanetsoeng tsa tšebeletso, WiFi e se nang mohala le mesebetsi ea ho amohela optical CATV. Popontshwa ena e bulela tsela bakeng sa ho hokahana le ho abelana ka seqo ka lapeng, ho fana ka tshebeletso e sa sitisweng ya Inthanete le kgaso e ngata ya dikheibole le dikahare tsa thelevishene. Ka CATV ONU, malapa a ka amohela bokamoso ba khokahanyo le ho natefeloa ke Marang-rang a lebelo le phahameng, thelevishene ea boleng bo holimo le liphihlelo tsa boithabiso tse ke keng tsa bapisoa.
