Chii chinonzi AON?
AON is an active optical network, kunyanya inotora point-to-point (PTP) network architecture, uye mushandisi wega wega anogona kuve neakazvitsaurira optical fiber mutsara. Active optical network inoreva kutumirwa kwerouters, switching aggregators, active optical equipment uye zvimwe zvekuchinja midziyo pakati pepakati hofisi midziyo uye mushandisi kugovera zvikamu panguva yechiratidzo chekufambisa. Aya ma switchgears anofambiswa nemagetsi kubata chiratidzo chekugovera uye masaini masaini kune chaiwo vatengi. Active optical equipment inosanganisira chiedza sosi (laser), optical receiver, optical transceiver module, optical amplifier (fiber amplifier uye semiconductor optical amplifier).
Chii chinonzi PON?
PON iPassive Optical Network, inonongedzera-kune-multipoint network, uye ndiyo tekinoroji huru yeFTTB/FTTH. Passive optical network inoreva ODN (optical distribution network) inongoshandisa optical fibers uye passive components, uye inongoda kushandisa mhenyu midziyo panzvimbo yechiratidzo uye chiratidzo chekugamuchira kupera. Mune yakajairwa PON system, iyo optical splitter ndiyo musimboti, uye optical splitter inoshandiswa kuparadzanisa uye kuunganidza masaini masaini anofambiswa kuburikidza netiweki. Aya akapatsanura ePON ane bidirectional. Munzira yakadzika, masevhisi akawanda akadai seIP data, izwi, uye vhidhiyo anogoverwa neiyoOLTiri muhofisi yepakati mune yekutepfenyura modhi kuburikidza ne1: N passive optical splitter muODN Kune vese.ONUzvikamu paPON; munzira yekumusoro, ruzivo rwesevhisi yakawanda kubva kune imwe neimweONUinosanganiswa kune imwechete optical fiber kuburikidza ne1: N passive optical musanganiswa muODN pasina kupindirana, uye pakupedzisira inotumirwa kuneOLTpacentral office kuitira reception kupera.
A passive optical network inosanganisira optical line terminal (OLT) yakaiswa pachiteshi chepakati chekutonga, uye boka rekuenzanisa optical network units (ONUs) yakaiswa panzvimbo yevashandisi. Iyo optical distribution network (ODN) pakati peOLTuyeONUine optical fibers uye passive splitters kana couplers. PON yakakamurwa kuita matatu tekinoroji zviyero: ATM-based APON (ATM PON), Ethernet-based EPON (Ethernet PON), uye GPON (Gigabit PON) zvichibva paGeneral Frame Protocol.
Mune network yeAON, mushandisi ane mutsara wakatsaurirwa optical fiber, iyo iri nyore kune gare gare kugadzirisa network, kuwedzera kwesimba, kusimudzira network, etc. Mukuwedzera, iyo AON network inovhara zvakasiyana-siyana zvemakiromita anenge 100; iyo PON network inowanzoganhurwa kune fiber optic tambo dzinosvika makiromita makumi maviri. AON inonyanya kutungamira zvikwangwani zvemaziso kuburikidza nemidziyo inoshanda, uye PON inoshandisa zvigadziriso zvisina magetsi, izvo zvinoguma nemitengo yakakwira yeAON network deployment kupfuura PON.
