Wireless router;ONU;OLT;fiber optic transceiver terminology explanation

1. AP, router e se nang mohala,e fetisetsa mats'oao a marang-rang ka lipara tse sothehileng.Ka pokello ea AP, e fetola matshwao a motlakase hore e be matshwao a radio ebe e a romela.

2. ONU (Optical Network Unit)yuniti ea marang-rang ea optical.Lisebelisoa tsa marang-rang tsa PON, PON e sebelisa fiber e le 'ngoe ea optical ho hokahanya le OLT, ebe OLT e amana le ONU.ONU e fana ka data, IPTV (Interactive Internet Television), lentsoe le litšebeletso tse ling.Boema-kepe ba PON mona bo bua ka boema-kepe bo ho OLT.Boema-kepe bo le bong ba PON bo lumellana le sekhahla se le seng sa optical.PON (Passive Optical Network) marang-rang a se nang letho.Boema-kepe ba PON hangata bo bua ka boema-kepe bo tlase ba OLT mme bo hokahantsoe le sekhechana sa mahlo.Boema-kepe bo ka holimo ho ONU bo ka boela ba bitsoa boema-kepe ba PON.Optical modem e bua ka modem ea fiber optic, 'me lisebelisoa tsohle tsa phetoho ea mosebelisi oa fiber optic li ka bitsoa modem ea optical.Modulation ke ho fetolela matshwao a dijithale hore e be matshwao a analoge a fetisetswang mehalang ya mehala, mme demodulation ke ho fetolela matshwao a analoge hore e be matshwao a dijithale, ka kopanelo a bitswang modem.Re sebelisa mehala ea mohala ho fetisa matšoao a analoge, ha li-PC li fetisa matšoao a dijithale.Ka hona, ha o hokela Inthaneteng ka mohala oa mohala, o tlameha ho sebelisa modem.

3. ONT (Optical Nerwork Unit)lisebelisoa tsa marang-rang tsa optical, tse lekanang le ONU.Ke sesebelisoa sa marang-rang sa optical se sebelisoang qetellong ea mosebedisi.Phapang ke: ONT ke setsi sa marang-rang sa optical, se fumanehang ka ho toba qetellong ea mosebedisi, ha ONU e le mochine oa marang-rang oa optical, 'me ho ka' na ha e-ba le marang-rang a mang pakeng tsa eona le mosebedisi, joalo ka Ethernet.Lihlahisoa tsa CeitaTech's ONU/ONT li ka sebelisoa e le lihlahisoa tsa ONU/ONT kapa joalo ka li-routers.Sehlahisoa se le seng se na le lisebelisoa tse ngata.

4. OLT (terminal ea optical line)optical line terminal, lisebelisoa tsa terminal tse sebelisetsoang ho hokahanya lithapo tsa optical fiber trunk.Mesebetsi: (1) Romela data ea Ethernet ho ONU (Optical Network Unit) ka mokhoa oa ho phatlalatsa, (2) Qala le ho laola mokhoa oa ho phalla le ho tlaleha boitsebiso bo fapaneng, (3) Abela marang-rang ho ONU, ke hore, laola ho qala ha ONU ho romella data.nako ea ho qala le ho romella boholo ba fensetere.Marang-rang a kopantsoeng pakeng tsa thepa ea ofisi e bohareng (OLT) le lisebelisoa tsa mosebedisi (ONU / ONT) ka marang-rang a optical distribution network (ODN) a entsoeng ka lithapo tsa optical tse sa sebetseng le li-splitter tsa optical / combiners.

5. Opticalfiber transceiverke Ethernet phetiso yuniti ya phetiso ya mecha ea phatlalatso e fapanyetsanang sebaka se sekhuts'oane sothehileng matshwao a motlakase le matshwao a malelele a optical.E boetse e bitsoa photoelectric converter (Fiber Converter) libakeng tse ngata..Hangata sehlahisoa se sebelisoa libakeng tsa sebele tsa marang-rang moo lithapo tsa Ethernet li ke keng tsa koahela 'me fiber ea optical e lokela ho sebelisoa ho atolosa sebaka sa phetisetso,' me hangata e behiloe sebakeng sa ts'ebeliso ea marang-rang ea marang-rang a libaka tsa metse e meholo ea broadband;ho thusa ho hokahanya mile ea ho qetela ea likhoele tsa fiber optic ho marang-rang a libaka tsa metropolitan le Marang-rang a kantle.
