1. AP, wireless router,inotumira masaini etiweki kuburikidza nemapeya akamonyoroka. Kuburikidza nekuunganidzwa kweAP, inoshandura masaini emagetsi kuita masaini eredhiyo uye oatumira kunze.
2. ONU (Optical Network Unit)Optical network unit. PON network midziyo, PON inoshandisa imwe optical fiber kuti ibatane neOLT, uye ipapo OLT yakabatana neONU. ONU inopa data, IPTV (Interactive Internet Television), izwi uye mamwe masevhisi. Chiteshi chePON pano chinoreva chiteshi chiri paOLT. Imwe chiteshi chePON inoenderana neapo optical splitter. PON (Passive Optical Network) passive optical network. Iyo PON port kazhinji inoreva kune yakadzika chiteshi cheOLT uye yakabatana kune yekuona kupatsanura. Chiteshi chepamusoro cheONU chinogonawo kunzi PON port. Optical modem inoreva fibre optic modem, uye ese fiber optic mushandisi-yekupedzisira shanduko midziyo inogona kunzi pamwe chete seOptical modem. Modulation ndeye kushandura masaini edhijitari kuita masaini eanalog anofambiswa pamitsara yefoni, uye demodulation ndeye kushandura masaini eanalog kuita masaini edhijitari, pamwe chete anonzi modem. Isu tinoshandisa mitsara yenhare kutumira masaini eanalogi, ukuwo maPC achitumira masaini edhijitari. Naizvozvo, kana uchibatanidza kuInternet kuburikidza netambo yefoni, unofanirwa kushandisa modem.
3. ONT (Optical Nerwork Unit)Optical network michina, yakaenzana neONU. Icho chinhu che optical network chinoshandiswa pamagumo emushandisi. Musiyano ndewekuti: ONT ndeye optical network terminal, inowanikwa zvakananga kumagumo evashandisi, nepo ONU iri optical network unit, uye panogona kunge paine mamwe ma network pakati payo nemushandisi, senge Ethernet. CeitaTech's ONU/ONT zvigadzirwa zvinogona kushandiswa seONU/ONT zvigadzirwa kana semarouta. Chigadzirwa chimwe chine mashandisiro akawanda.
4. OLT (Optical line terminal)Optical line terminal, terminal michina inoshandiswa kubatanidza optical fiber trunk mitsara. Mabasa: (1) Tumira Ethernet data kuONU (Optical Network Unit) nenzira yekutepfenyura, (2) Tanga uye udzore nzira yekufamba uye rekodha ruzivo rwakasiyana, (3) Govera bandwidth kuONU, ndiko kuti, kutonga kutanga kweONU kutumira data. kutanga nguva uye kutumira hwindo saizi. Network yakabatana pakati pepakati hofisi midziyo (OLT) uye mushandisi midziyo (ONU/ONT) kuburikidza neyekugovera network network (ODN) inoumbwa nemapassive optical cables uye optical splitters/combiners.
5. Opticalfiber transceiveriEthernet transmission media conversion unit iyo inotsinhana kure-kure-monyoroka masaini masaini emagetsi uye kureba-kureba kwemaziso masaini. Inonzi zvakare photoelectric converter (Fiber Converter) munzvimbo dzakawanda. . Chigadzirwa chacho chinowanzo shandiswa munzvimbo chaidzo dzenetiweki uko tambo dzeEthernet dzisingakwanisi kuvhara uye optical fiber inofanira kushandiswa kuwedzera nhambwe yekufambisa, uye inowanzoiswa muchikamu chekushandisa chebroadband metropolitan area network; kubatsira kubatanidza maira ekupedzisira efiber optic mitsara kune metropolitan area network uye Panetiweki yekunze.
