ONU.Mubisanzwe, ibikoresho bifite ibikoresho byakira optique, uplink optique yohereza, hamwe na amplifier nyinshi yikiraro kugirango ikurikirane imiyoboro yitwa optique node.PON ikoresha fibre optique imwe kugirango ihuze na OLT, hanyuma OLT ihuze na ONU.ONU itanga serivisi nkamakuru, IPTV (Interineti ikora kuri interineti), ijwi (ukoresheje IAD, Igikoresho cyinjira), kandi ikamenya rwose "gukinisha gatatu".
Muri rusange, ibikoresho bya ONU birashobora gushyirwa mubice ukurikije ibintu bitandukanye bisabwa nka SFU, HGU, SBU, MDU, na MTU.
1. Ubwoko bwa SFU bwohereza ONU
Ibyiza byubu buryo bwo kohereza nuko umutungo wurusobe ari mwinshi, kandi birakwiriye ingo zigenga mubihe bya FTTH.Irashobora kwemeza ko umukoresha arangije afite umurongo mugari wa enterineti, ariko ntabwo ikubiyemo imirimo igoye yo murugo.SFU muri ibi bidukikije ifite uburyo bubiri busanzwe: gutanga ibyambu byombi bya Ethernet na POTS;no gutanga ibyambu bya Ethernet gusa.Twabibutsa ko SFU muburyo bwombi ishobora gutanga imiyoboro ya coaxial kugirango yorohereze serivisi za CATV, kandi irashobora no gukoreshwa ninzugi zurugo kugirango byorohereze itangwa rya serivisi zongerewe agaciro.Ibi birashobora no gukoreshwa mubigo bidakenera guhana amakuru ya TDM
2. HGU andika ONU yoherejwe
Ingamba zo kohereza ubwoko bwa HGU ONU terminal isa niy'ubwoko bwa SFU, usibye ko imikorere ya ONU na RG ihujwe mubyuma.Ugereranije na SFU, irashobora kumenya imikorere igoye yo kugenzura no kuyobora.Muri ubu buryo bwo kohereza, U-shusho yimbere yubatswe mubikoresho bifatika kandi ntabwo itanga intera.Niba ibikoresho bya xDSLRG bisabwa, ubwoko bwinshi bwimikorere burashobora guhuzwa neza numuyoboro murugo, ibyo bikaba bihwanye numuryango winzu hamwe na EPON uplink interface.Byakoreshejwe mubihe bya FTTH.
3. Ubwoko bwa SBU ONU yoherejwe
Iki gisubizo cyoherejwe kirakenewe cyane muburyo bwo kubaka urusobe rwabakoresha imishinga yigenga muburyo bwa porogaramu ya FTTO, kandi ni impinduka yibikorwa bishingiye kuri gahunda yo kohereza SFU na HGU.Umuyoboro uri munsi yibi bikorwa ushobora gushyigikira ibikorwa byogukoresha umurongo mugari kandi bigaha abakoresha interineti itandukanye yamakuru arimo El interface, interineti ya Ethernet, hamwe na POTS, ishobora guhuza ibikenerwa ninganda mu itumanaho ryamakuru, itumanaho ryijwi, na TDM wigenga. serivisi z'umurongo.Ibisabwa.Imigaragarire ya U-mubidukikije irashobora gutanga inganda zifite imiterere yimiterere itandukanye, kandi imikorere irakomeye.
4. Ubwoko bwa MDU bwohereza ONU
Iki gisubizo cyoherejwe gikwiranye no kubaka imiyoboro munsi yuburyo bwinshi busaba nkabakoresha benshi FTTC, FTTN, FTTCab, na FTTZ.Niba abakoresha urwego rwimishinga badakeneye serivisi za TDM, iki gisubizo kirashobora no gukoreshwa muburyo bwo kohereza imiyoboro ya EPON.Iyi gahunda yo kohereza irashobora guha abakoresha benshi serivisi zogutumanaho amakuru mugari harimo serivisi za Ethernet / IP, serivisi za VoIP, na serivisi za CATV nubundi buryo bwa serivisi nyinshi, kandi ifite ubushobozi bukomeye bwo kohereza amakuru.Buri cyambu cyitumanaho gishobora guhura nu mukoresha, bityo ugereranije, igipimo cyacyo cyo gukoresha kiri hejuru.
5. Ubwoko bwa MTU bwohereza ONU
Iki gisubizo cyo kohereza ni impinduka zubucuruzi zishingiye kubisubizo bya MDU.Irashobora guha abakoresha imishinga myinshi hamwe na serivise zinyuranye zirimo interineti ya Ethernet hamwe na POTS, kandi irashobora guhura na serivisi zitandukanye nkijwi, amakuru, hamwe na TDM yatijwe kumurongo wibigo.bikenewe.Niba imiterere-yuburyo bwo gushyira mubikorwa ikoreshwa muguhuza, ibikorwa byubucuruzi bikize kandi bikomeye birashobora kugerwaho.
