LM240TUW5 dual-mode ONU/ONT e sebetsa ho FTTH/FTTO, ho fana ka tshebeletso ya data e itshetlehileng hodima netweke ya EPON/GPON.LM240TUW5 e ka kopanya ts'ebetso ea mohala ka ho kopana le litekanyetso tsa tekheniki tsa 802.11 a/b/g/n/ac, e ts'ehetsa lets'oao la waelese la 2.4GHz le 5GHz hape.E na le litšobotsi tsa matla a phunyeletsang a matla le ho koahela ka bophara.E ka fa basebelisi ts'ireletso e sebetsang haholoanyane ea phetiso ea data.'Me e fana ka lits'ebeletso tsa TV tsa boleng bo holimo ka 1 CATV Port.
Ka lebelo la ho fihla ho 1200Mbps, 4-Port XPON ONT e ka fa basebelisi mokhoa o makatsang oa ho palama marang-rang, ho letsa mehala ea inthanete le papali ea inthaneteng.Ho feta moo, ka ho amohela antenna ea kantle ea Omni-directional, LM240TUW5 e ka eketsa haholo marang-rang a se nang mohala le kutlo, e u nolofalletsang ho amohela matšoao a waelese k'honeng e hole ea lehae la hau kapa ofisi.U ka boela ua hokahanya le TV le ho ntlafatsa bophelo ba hau.
ONU (Optical Network Unit) ke sesebelisoa sa optical transmission se sebelisoang tsamaisong ea puisano ea fiber optic e nang le mesebetsi e 'meli ea "ho romela" le "ho amohela".Ke sesebelisoa sa marang-rang a optical se kopanyang lisebelisoa tsa optical ho lisebelisoa tsa mosebedisi.Fiber optic communication ke thekenoloji ea puisano e sebelisang leseli e le letšoao la Bellman, ONU ke e 'ngoe ea lisebelisoa tsa bohlokoa ka ho fetisisa bakeng sa puisano le phetisetso ea matšoao.Ha ho bapisoa le lisebelisoa tse tloaelehileng tsa marang-rang, ONU e na le litšobotsi tse peli:
Taba ea pele, mabapi le khokahanyo ea 'mele, ONU e sebelisa likhoele tsa fiber optic ho fapana le likhoele tsa marang-rang tse tloaelehileng.Hobane thapo ea fiber optic e na le lebelo le phahameng la phetisetso, matla a phetiso ea data e phahameng, le sebaka se selelele sa phetiso, e loketse haholo phetiso ea data e potlakileng le e phahameng.
Ea bobeli, ONU e sebelisa theknoloji e ikhethang ea TDMA (Time Division Multiple Access) ho fetisetsa data ka botšepehi ho basebelisi ba fapaneng ka linako tse fapaneng ho netefatsa botsitso le ts'ireletso ea phetiso ea data.
Litlhoko
Ntlafatso ea Machaba a Kopaneng e potlakisitse haholo nts'etsopele ea marang-rang.Scope ka kakaretso e na le lintlha tse tharo tse latelang:
1. Fumana bophara ba ntlo
Ho phaella moo, litlhoko tsa digital tsa malapa a kajeno li eketsehile 'me ho hlokahala hore ho romelloe boitsebiso bo eketsehileng sebakeng sa lehae, se hlokang tšehetso e potlakileng le e sebetsang.Nakong e fetileng, theknoloji ea ADSL e ne e na le mefokolo mabapi le lebelo la phetisetso, empa UN e sebelisa fiber optics ho fihlela basebelisi ba ho qetela.E ts'ehetsa lebelo le phahameng la li-megabits tse makholo, tse tla fihlela litlhoko tsa ho romella lintlha tse ngata.
2. Ho fihla mahaeng
Libakeng tsa mahaeng, phihlello ea marang-rang e tloaelehileng e thata ho fihlela litlhoko tsa basebelisi ka lebaka la meaho e fokolang.Machaba a Kopaneng a sebelisa theknoloji ea fiber optic e ka fetisang lintlha libakeng tse telele, ho fana ka litšebeletso tse potlakileng libakeng tsa mahaeng le ho kenya letsoho haholo ho meralo ea motheo ea Machaba a Kopaneng.
3. Sebopeho sa khoebo
Mabapi le khoebo, ha o romela lintlha libakeng tse fapaneng, ONU e sebelisa mekhoa e fapaneng le e fapaneng ea mekhoa e mengata, e sa ntlafatse ts'ebetso ea marang-rang feela, empa hape e ntlafatsa tšireletso ea phetisetso ea data.khampani.

Hajoale, ka nts'etsopele ea 5G, komporo ea maru le mahlale a mang, marang-rang a setso a ke ke a fihlela tlhokahalo e ntseng e eketseha.Ka lehlakoreng le leng, theknoloji ea fiber optic e na le melemo ea phetisetso ea lebelo le phahameng, botsitso bo botle le bandwidth e pharaletseng.Ka hona, ONU e le sesebelisoa se atolositsoeng se na le menyetla e mengata ea ntlafatso.Nakong e tlang, lipatlisiso tse ling li ka etsoa libakeng tse latelang:
1. Ho ntlafatsa thekenoloji ho ntlafatsa hardware le lebelo la ho jarolla
Etsa lipatlisiso tse tsoelang pele mabapi le theknoloji e amanang le eona, ho tsepamisa maikutlo ho ntlafatsa botsitso ba hardware, ho eketsa lebelo la phetisetso ka ho fokotsa lisebelisoa tse senyang matla, le ho fokotsa haholo litšenyehelo tsa phetisetso ea marang-rang.
2. Eketsa sebaka sa ts'ebeliso le ho matlafatsa tsamaiso ea litaba tsa sechaba
Likopo tsa UN ha li felle feela malapeng le likhoebong.Nakong e tlang, libaka tsa kopo li ka atolosoa, 'me tsamaiso ea tlhahisoleseding ea sechaba e ka sebelisoa libakeng tse kang ho haha toropo e bohlale le ho aha Inthanete ea Lintho ho ntlafatsa tsamaiso ea tlhahisoleseding.
3. Matlafatsa ts'ireletso ea marang-rang le ho ntlafatsa ts'ireletso ea basebelisi
Ha botlokotsebe ba marang-rang bo ntse bo fetoha bo fapaneng le bo rarahaneng, ts'ireletso ea marang-rang e tlameha ho matlafatsoa ho netefatsa tšireletso e felletseng le e felletseng ea phetiso ea data ea basebelisi.
