1. AP, rauta yopanda zingwe,imatumiza ma sign a netiweki kudzera pamagulu opotoka. Kupyolera mu kuphatikiza kwa AP, imasintha ma siginecha amagetsi kukhala ma wayilesi ndikuwatumiza.
2. ONU (Optical Network Unit)Optical network unit. Zida zapaintaneti za PON, PON imagwiritsa ntchito chingwe chimodzi cholumikizira ku OLT, kenako OLT imalumikizidwa ndi ONU. ONU imapereka deta, IPTV (Interactive Internet Television), mawu ndi mautumiki ena. Doko la PON apa likuyimira doko pa OLT. Doko limodzi la PON limafanana ndi choboola chimodzi cha kuwala. PON (Passive Optical Network) passive Optical network. Doko la PON nthawi zambiri limatanthawuza ku doko lakumunsi la OLT ndipo limalumikizidwa ndi chogawa cha kuwala. Doko lakumtunda la ONU limathanso kutchedwa doko la PON. Modemu ya kuwala imatanthawuza modemu ya fiber optic, ndipo zida zonse zosinthira za fiber optic zimatha kutchedwa kuti modemu ya kuwala. Kusinthasintha ndikusintha ma sign a digito kukhala ma analogi omwe amatumizidwa pamizere ya foni, ndipo kutsitsa ndikutembenuza ma sign a analogi kukhala ma siginecha a digito, pamodzi otchedwa modemu. Timagwiritsa ntchito matelefoni kutumizira ma analogi, pomwe ma PC amatumiza ma siginecha a digito. Chifukwa chake, mukalumikiza intaneti kudzera pa foni yam'manja, muyenera kugwiritsa ntchito modemu.
3. ONT (Optical Nerwork Unit)zida zamagetsi zamagetsi, zofanana ndi ONU. Ndi chipangizo chamagetsi chamagetsi chomwe chimagwiritsidwa ntchito kumapeto kwa wosuta. Kusiyanitsa ndiko: ONT ndi optical network terminal, yomwe ili molunjika kumapeto kwa wogwiritsa ntchito, pamene ONU ndi optical network unit, ndipo pakhoza kukhala maukonde ena pakati pake ndi wogwiritsa ntchito, monga Ethernet. Zogulitsa za CeitaTech za ONU/ONT zitha kugwiritsidwa ntchito ngati zinthu za ONU/ONT kapena ngati ma router. Chinthu chimodzi chimakhala ndi ntchito zambiri.
4. OLT (optical line terminal)Optical line terminal, zida zolumikizira zomwe zimagwiritsidwa ntchito kulumikiza mizere ya optical fiber trunk. Ntchito: (1) Tumizani deta ya Ethernet ku ONU (Optical Network Unit) m'njira yowulutsa, (2) Yambitsani ndikuwongolera njira yoyambira ndikulemba zambiri, (3) Perekani bandwidth ku ONU, ndiko kuti, kuwongolera kuyamba kwa ONU kutumiza deta. nthawi yoyambira ndikutumiza kukula kwazenera. Maukonde olumikizidwa pakati pa zida zapakati paofesi (OLT) ndi zida zogwiritsa ntchito (ONU/ONT) kudzera pa netiweki ya optical distribution network (ODN) yopangidwa ndi zingwe zowoneka bwino komanso zogawanitsa / zophatikiza.
5. Kuwalafiber transceiverndi Ethernet transmission media conversion unit yomwe imasinthanitsa ma siginoloji amagetsi opindika mtunda waufupi ndi ma siginecha akutali atali. Imatchedwanso photoelectric converter (Kusintha kwa Fiber) m'malo ambiri. . Chogulitsacho chimagwiritsidwa ntchito m'malo enieni amtaneti pomwe zingwe za Efaneti sizingathe kubisala ndipo ulusi wa kuwala uyenera kugwiritsidwa ntchito kukulitsa mtunda wotumizira, ndipo nthawi zambiri amayikidwa munjira yolumikizira maukonde a Broadband metropolitan area; Kuthandizira kulumikiza mtunda womaliza wa mizere ya fiber optic ku netiweki ya madera a metropolitan ndi Pamaneti akunja.
