ONU (Ishami ry'Umuyoboro w'Amatara) Igice cy'umuyoboro w'amatara, ONU igabanyijemo igice cy'umuyoboro w'amatara ukorana n'igice .... Muri rusange, ibikoresho bifite ibikoresho byakira amatara, ibikoresho byo kohereza amatara bihuza n'amatara, n'ibindi bikoresho byinshi byo kugenzura umuyoboro byitwa node y'amatara. PON ikoresha fibre imwe y'amatara kugira ngo ihuze na OLT, hanyuma OLT igahuzwa na ONU. ONU itanga serivisi nka data, IPTV (Televiziyo ya Interactive Internet), ijwi (ikoresheje IAD, Ibikoresho byo Kugeramo), kandi igakora porogaramu "zitatu".
Muri rusange, ibikoresho bya ONU bishobora gushyirwa mu byiciro hakurikijwe uburyo butandukanye bwo kubikoresha nka SFU, HGU, SBU, MDU, na MTU.
1. Gushyiramo ONU yo mu bwoko bwa SFU
Akamaro k'ubu buryo bwo gushyiraho amakuru ni uko umutungo wa interineti ari mwinshi, kandi ukwiriye ingo zigenga muri FTTH. Ishobora kwemeza ko umukoresha afite imikorere yo kugera kuri interineti, ariko ntikubiyemo imikorere igoye yo kwinjira mu rugo. SFU muri ubu buryo ifite imiterere ibiri ihuriweho: itanga imiyoboro ya Ethernet na POTS; kandi itanga imiyoboro ya Ethernet gusa. Tugomba kumenya ko SFU muri ubwo buryo bwombi ishobora gutanga imikorere ya coaxial cable kugira ngo yorohereze ishyirwa mu bikorwa rya serivisi za CATV, kandi ishobora no gukoreshwa n'imiyoboro yo mu rugo kugira ngo yorohereze gutanga serivisi ziyongereye ku gaciro. Iyi mimerere irareba kandi ibigo bidakeneye guhanahana amakuru ya TDM.
2. Gushyira ONU mu bwoko bwa HGU
Ingamba zo gushyiraho terminal ya HGU ONU isa n'iya SFU, uretse ko imikorere ya ONU na RG ihujwe muri hardware. Ugereranyije na SFU, ishobora gukora imirimo igoye yo kugenzura no gucunga. Muri iki gihe cyo gushyiraho, interface ifite ishusho ya U iba yubatswe mu gikoresho gifatika kandi ntitanga interface. Niba ibikoresho bya xDSLRG bikenewe, ubwoko bwinshi bwa interfaces bushobora guhuzwa mu buryo butaziguye n'umuyoboro wo mu rugo, bingana n'irembo ryo mu rugo rifite interface ya EPON. Ikoreshwa ku bihe bya FTTH.
3. Gushyira mu bikorwa ONU yo mu bwoko bwa SBU
Ubu buryo bwo gushyiraho amakuru bukwiriye cyane mu kubaka umuyoboro w’abakoresha ubucuruzi bwigenga muri porogaramu ya FTTO, kandi ni impinduka mu bigo bishingiye ku buryo bwo gushyiraho amakuru bwa SFU na HGU. Umuyoboro uri muri ubu buryo bwo gushyiraho amakuru ushobora gushyigikira imikorere ya interineti ikoresha umurongo mugari no guha abakoresha uburyo butandukanye bwo kugenzura amakuru harimo na El interface, Ethernet interface, na POTS interface, bishobora guhaza ibyifuzo by’ibigo mu itumanaho ry’amakuru, itumanaho ry’amajwi, na serivisi z’umurongo wigenga wa TDM. Ibisabwa mu ikoreshwa. Umuyoboro ufite ishusho ya U mu bidukikije ushobora guha ibigo imiterere y’umuyoboro ifite imiterere itandukanye, kandi imikorere yayo ni ikomeye cyane.
4. Gushyira ONU mu bwoko bwa MDU
Iyi gahunda yo gushyiraho amakuru ikwiriye mu kubaka umuyoboro w’itumanaho hakoreshejwe uburyo bwinshi nka FTTC, FTTN, FTTCab, na FTTZ. Niba abakoresha bo ku rwego rw’ikigo badakeneye serivisi za TDM, iyi gahunda ishobora no gukoreshwa mu gushyiraho umuyoboro wa EPON. Iyi gahunda yo gushyiraho amakuru ishobora guha abakoresha benshi serivisi zo gutumanaho kuri interineti harimo serivisi za Ethernet / IP, serivisi za VoIP, na serivisi za CATV n’ubundi buryo bwinshi bwo kohereza amakuru, kandi ifite ubushobozi bukomeye bwo kohereza amakuru. Buri muyoboro wayo w’itumanaho ushobora kuba uhuye n’umukoresha w’umuyoboro w’itumanaho, bityo ugereranije, igipimo cyo gukoresha umuyoboro w’itumanaho kiri hejuru.
5. Gushyira ONU mu bwoko bwa MTU
Iyi gahunda yo gushyiraho porogaramu ni impinduka mu bucuruzi ishingiye ku gisubizo cyo gushyiraho porogaramu cya MDU. Ishobora guha abakoresha b’ibigo byinshi serivisi zitandukanye zirimo imiyoboro ya Ethernet na POTS, kandi ishobora guhaza serivisi zitandukanye nka serivisi z’ijwi, amakuru, na serivisi z’umurongo wa TDM zikenewe n’ibigo. Iyo imiterere y’uburyo bwo gushyira mu bikorwa porogaramu ikoreshejwe hamwe, imirimo y’ubucuruzi ikungahaye kandi ikomeye ishobora kugerwaho.
