I-ONU, eyaziwa nangokuthi i-Optical Network Unit, evame ukubizwa ngokuthi i-Optical Cat, isebenzisa ubuchwepheshe be-PON yokufinyelela i-fiber optic nge-fiber optic transmission medium. Njengamanje iyindlela yokufinyelela enkulumweni evamile yabaqhubi bezokuxhumana bomhlaba wonke, enezinzuzo ezifana nezindleko eziphansi, umkhawulokudonsa omkhulu, ukubambezeleka okuphansi, ukugcinwa okungenakulungiswa, kanye nokuphathwa okulula.
I-EOC: Igama eligcwele i-Ethernet Over Cable, idatha ye-Ethernet idluliselwa ngamakhebula angama-coaxial. Isekelwe kubuchwepheshe bokufinyelela bephrothokholi ye-Ethernet esetshenziswa kuzintambo ze-cable TV coaxial, ezinomkhawulokudonsa ophindwe kabili we-100M. Kuyindlela yokufinyelela eyamukelwa umsakazo nomabonakude. Ezinsukwini zakuqala, o-opharetha bomsakazo nomabonakude babesebenzisa indlela yokusakaza yendlela eyodwa ukuze bathumele izinsiza kubasebenzisi ukuze bathole ukwamukelwa. Ekuguqulweni kwe-bidirectional okwalandela kwamanethiwekhi kamabonakude wekhebula, ubuchwepheshe be-EOC baguquguquka, kusetshenziswa inethiwekhi yehhovisi ye-EPON+EOC, eyayixhunywe ekugcineni komsebenzisi i-EOC ngezintambo ze-coaxial. Ngenxa yezici ezifana nomkhawulokudonsa kanye nezingqinamba zezindleko, abaqhubi bemisakazo nethelevishini kancane kancane bamukela ubuchwepheshe be-PON ukuze badlulise, njenge-Shenzhen Tianwei, esivele ifake izintambo ze-fiber optic ezakhiweni ezintsha.
CM: Imodemu yekhebula, igama layo eligcwele okuyimodemu yekhebula, evame ukubizwa nge-coaxial cat. Kuyidivayisi yokufinyelela idatha ngentambo ye-coaxial ye-cable TV. Kuyindlela yokufinyelela esetshenziswa umsakazo nomabonakude. Uhlelo lokuphatha lwe-CMTS lusetshenziswa ekugcineni. I-Cable Modemu iguqula isignali yedijithali ekhuphukayo (IP) ibe isignali yefrikhwensi yomsakazo we-analog (RF) ukuze idluliselwe, kuyilapho umfula ongezansi uguqula isignali yomsakazo we-analog (RF) ibe isignali yedijithali (IP) ukuze yamukele. I-Cable Modem isetshenziswa kakhulu opharetha bomsakazo nomabonakude (i-Shenzhen Tianwei CM inomkhawulokudonsa omkhulu ongu-100M), kodwa ngenxa yezinto ezifana nomkhawulokudonsa kanye nezingqinamba zezindleko, le ndlela yokufinyelela nayo iyayekwa kancane kancane.
I-ADSL: I-Asymmetric Digital Subscriber Line, evame ukwaziwa ngokuthi i-E-Cat, iyindlela yokufinyelela eyamukelwa ama-opharetha okuqala. Isebenzisa ubuchwepheshe be-frequency division futhi i-transmission medium intambo yocingo. Ihlukanisa amasignali anemvamisa ephansi kanye namasignali amaza aphezulu asakazwa izintambo zocingo ezijwayelekile. Iwubuchwepheshe bokudluliswa kwedatha ngesivinini esiphezulu emigqeni yocingo evamile. Ayikwazi ukuhlangabezana nesidingo sokufinyelela kwenethiwekhi ngesivinini esiphezulu kanye nezindleko eziphezulu, kancane kancane ithathelwa indawo ubuchwepheshe be-PON.
I-Shenzhen Haidwiwei Optoelectronics ingumkhiqizi ochwepheshe weI-ONUimishini yekati ye-optical kanye nokuxhumana okuhlakaniphileI-ONUoptical cat module. Inkampani yethu njengamanje ithengisa imishini yezokuxhumana ehlukahlukene enokuxhumana okukhuphuka naphansi, okufana nama-fiber optic transceivers, amaswishi e-Ethernet,OLTimishini yekati yokubona,I-ONUoptical cat imishini, nokunye. Uma ungathanda ukufunda okwengeziwe ngolwazi lobuchwepheshe bezokuxhumana, sicela ukhululeke ukuxhumana nenkampani yethu.
