ONU (Optical Network Unit) Optical network unit, ONU yakakamurwa kuita inoshanda optical network unit uye passive optical network unit.Kazhinji, michina ine optical receivers, uplink optical transmitters, uye akawanda mabhiriji amplifiers ekutarisisa network inonzi optical node.PON inoshandisa imwe optical fiber kubatanidza kuOLT, uyezve OLT yakabatana neONU.ONU inopa masevhisi akadai sedata, IPTV (Interactive Internet TV), izwi (uchishandisa IAD, Yakabatanidzwa Kupinda Chishandiso), uye inonyatso ziva "katatu-kutamba" zvikumbiro.
Pakazere, zvishandiso zveONU zvinogona kuiswa zvinoenderana neakasiyana maficha ekushandisa akadai SFU, HGU, SBU, MDU, uye MTU.
1. SFU mhando ONU deployment
Kubatsira kweiyi nzira yekuendesa ndeyekuti network zviwanikwa zvakawandisa, uye inokodzera mhuri dzakazvimiririra mune FTTH mamiriro.Inogona kuve nechokwadi chekuti mushandisi wekupedzisira ane Broadband yekuwana mabasa, asi haisanganisire yakaoma basa gedhi repamba.Iyo SFU munharaunda iyi ine maitiro maviri akafanana: kupa ese maEthernet ports uye POTS ports;uye kupa chete Ethernet ports.Izvo zvinofanirwa kucherechedzwa kuti iyo SFU mune ese ari maviri mafomu anogona kupa coaxial tambo mabasa kufambisa kuzadzikiswa kweCATV masevhisi, uye inogona zvakare kushandiswa nemasuwo epamba kufambisa kupihwa kweiyo kukosha-yakawedzerwa masevhisi.Iyi mamiriro anoshanda zvakare kumabhizinesi asingade kuchinjanisa TDM data
2. HGU mhando ONU deployment
Nzira yekuendesa yeHGU yerudzi rweONU terminal yakafanana neyemhando yeSFU, kunze kwekuti mabasa eONU neRG akabatanidzwa mune hardware.Kuenzaniswa neSFU, inogona kuona zvakanyanya kuomarara kutonga uye manejimendi mabasa.Mune ino mamiriro ekutumira, iyo U-yakaita interface inovakwa mumudziyo wenyama uye haipe chimiro.Kana midziyo ye xDSLRG ichidikanwa, mhando dzakawanda dzemafafiterani dzinogona kubatanidzwa zvakananga kunetiweki yepamba, iyo yakaenzana negedhi repamba rine EPON uplink interface.Inoshandiswa kune zviitiko zveFTTH.
3. SBU type ONU deployment
Iyi mhinduro yekuendesa inonyanya kukodzera kuvakwa kwetiweki yevashandisi vebhizinesi vakazvimiririra muFTTO application mode, uye ishanduko yebhizinesi inoenderana neSFU neHGU deployment scenarios.Iyo network iri pasi peiyi nharaunda yekutumirwa inogona kutsigira iyo Broadband yekuwana terminal basa uye inopa vashandisi akasiyana e data interfaces anosanganisira El interface, Ethernet interface, uye POTS interface, iyo inogona kuzadzisa zvinodiwa nemabhizinesi mukukurukurirana kwedata, kutaurirana kwezwi, uye TDM yakavanzika. line services.Zvido zvekushandisa.Iyo U-yakaumbwa interface munharaunda inogona kupa mabhizinesi ane furemu chimiro ane akasiyana hunhu, uye basa racho rine simba.
4. MDU type ONU deployment
Iyi mhinduro yekuendesa inokodzera kuvakwa kwetiweki pasi pemazhinji-mashandisirwo maitiro akadai seakawanda-mushandisi FTTC, FTTN, FTTCab, uye FTTZ.Kana vashandisi vebhizinesi-chikamu vasingade masevhisi eTDM, mhinduro iyi inogona kushandiswa zvakare kuEPON network deployment.Ichi chirongwa chekuendesa chinogona kupa vashandisi vakawanda vane Broadband data communication services kusanganisira Ethernet/IP masevhisi, VoIP masevhisi, uye CATV masevhisi uye mamwe akawanda-sevhisi modes, uye ine simba rekufambisa data.Imwe neimwe yezviteshi zvayo zvekutaurirana inogona kuenderana nemushandisi wetiweki, saka mukuenzanisa, chiyero chekushandisa kwayo network chakakwira.
5. MTU type ONU deployment
Iyi sarudzo yekuendesa ndeye shanduko yekutengeserana yakavakirwa pane iyo MDU deployment solution.Inogona kupa vashandisi vemabhizinesi akawanda akasiyana-siyana masevhisi ekubatanidza anosanganisira Ethernet interfaces uye POTS nzvimbo, uye inogona kusangana neakasiyana masevhisi akadai sezwi, data, uye TDM akarenda mutsara masevhisi emabhizinesi.need.Kana iyo slot-mhando yekumisikidza chimiro ichishandiswa musanganiswa, akapfuma uye ane simba bhizinesi mabasa anogona kuitika.
