Kugereranya kwa bitanu PON ishingiye kuri FTTX
Uburyo bugezweho bwo kwagura uburyo bwo guhuza imiyoboro ishingiye cyane cyane kuri PON ishingiye kuri FTTX. Ibyingenzi nibitekerezo bigira uruhare mubisesengura ryibiciro ni ibi bikurikira:
Costs Igiciro cyibikoresho byigice cyo kwinjira (harimo ibikoresho bitandukanye byinjira nimirongo, nibindi, ugereranije kuri buri murongo ukoresha)
Costs Amafaranga yo kubaka ubwubatsi (harimo amafaranga yubwubatsi nandi mafaranga yo hejuru, muri rusange 30% yikiguzi cyibikoresho byose)
Costs Amafaranga yo gukora no kuyitaho (mubisanzwe hafi 8% yikiguzi cyose kumwaka)
Rate Igipimo cyo kwishyiriraho ntigisuzumwa (ni ukuvuga igipimo cyo kwishyiriraho ni 100%)
Costs Igiciro cyibikoresho bisabwa kibarwa hashingiwe kubintu 500 byabakoresha
Icyitonderwa 1: Kwinjira kwa FTTX ntibireba ikiguzi cyicyumba cya mudasobwa yabaturage;
Icyitonderwa 2: ADSL2 + nta nyungu ifite ugereranije na ADSL mugihe intera yo kugera ari 3km. VDSL2 kuri ubu ntabwo ikoreshwa cyane, ntabwo rero igereranya rizakorwa mugihe kiri imbere;
Icyitonderwa 3: Kubona fibre optique ifite ibyiza bigaragara intera ndende.
FTTB + LAN
Ibiro bikuru byanyuze muri fibre optique (3km) kugeza hamwehinduray'ahantu ho gutura cyangwa inyubako, hanyuma igahuzwa na koridorhindurabinyuze muri fibre optique (0,95km), hanyuma ikanyuzwa kumurongo wanyuma ukoresheje umugozi wa 5 (0.05km). Kubarwa ukurikije icyitegererezo cyabakoresha 500 (utitaye ku giciro cyicyumba cyakagari), byibuze icyambu kimwe 24hindurana 21 koridorGuhindurabasabwa. Mugukoresha nyabyo, urwego rwinyongera rwahindurani Byongeyeho. Nubwo umubare rusange waGuhindurayiyongera, ikoreshwa rya moderi igiciro gito cya koridorGuhinduraigabanya igiciro cyose.
FTTH
Tekereza gushyira anOLTku biro bikuru, fibre imwe ya optique (4km) kugeza mucyumba cya mudasobwa yo hagati, mucyumba cya mudasobwa yo hagati igacamo ibice 1: 4 optique (0.8km) kuri koridor, hamwe na 1: 8 optique (0.2km) ) muri koridor ukoresha terminal. Kubarwa ukurikije icyitegererezo cy-abakoresha 500 (utitaye ku giciro cyicyumba cyakagari): Igiciro cyaOLTibikoresho bitangwa ku gipimo cy’abakoresha 500, bisaba byose hamwe 16OLTibyambu.
FTTC + EPON + LAN
Tekereza no gushyiraOLTku biro bikuru. Fibre optique imwe (4km) izoherezwa mubyumba bya mudasobwa nkuru yabaturage. Icyumba cya mudasobwa yo hagati yabaturage kizanyura muri 1: 4 optique (0.8km) igana ku nyubako. Muri buri koridor, hazakoreshwa 1: 8 optique itandukanya (0.2km). ) Jya kuri buri igorofa, hanyuma uhuze ukoresha terefone hamwe nicyiciro cya 5. Buri kimweONUifite imikorere ya Layeri 2. Urebye koONUifite ibyambu 16 FE, ni ukuvuga buri kimweONUirashobora kugera kubakoresha 16, ibarwa ukurikije urugero rwabakoresha 500.
FTTC + EPON + ADSL / ADSL2 +
Kubisabwa bimwe bya DSLAM kumanuka, tekereza gushyira anOLTku biro bikuru, hamwe na fibre imwe (5km) kuva ku biro byanyuma bya BAS kugera ku biro rusange birangirira, no ku biro rusange birangirira, inyura muri 1: 8 optique (4km) kugeza kuriONUmucyumba cya mudasobwa icyumba. UwitekaONUni mu buryo butaziguye na DSLAM binyuze muri FE Imigaragarire, hanyuma igahuzwa nu mukoresha urangije hamwe na kabili y'umuringa (1km). Irabarwa kandi hashingiwe ku moderi 500 y'abakoresha ihujwe na buri DSLAM (utitaye ku giciro cy'icyumba cy'akagari).
Ethernet
Ibiro bikuru byoherejwe binyuze muri fibre optique (4km) kugirango ikusanyirizwehinduray'abaturage cyangwa inyubako, hanyuma igahita yoherezwa kubakoresha kurangiza binyuze muri fibre optique (1km). Kubarwa ukurikije icyitegererezo cyabakoresha 500 (utitaye ku giciro cyicyumba cyakagari), byibuze 21 24-byegeranyeGuhindurabirakenewe, kandi 21 jambo ya kilometero 4 za fibre optique ya fibre optique yashyizwe mubyumba bya mudasobwa yo mu biro bikuru kugeza hamweGuhinduramu kagari. Kubera ko point-to-point optique Ethernet idakoreshwa muburyo bwo kubona umurongo mugari mugace utuyemo, mubusanzwe ikoreshwa gusa muguhuza abakoresha batatanye. Kubwibyo, ishami ryubwubatsi ryayo ritandukanye nubundi buryo bwo kugera, kuburyo bwo kubara nabwo buratandukanye.
Duhereye ku isesengura ryavuzwe haruguru, birashobora kugaragara ko gushyira optique ya optique bizagira ingaruka itaziguye kumikoreshereze ya fibre, nayo igira ingaruka kubiciro byo kubaka umuyoboro; igiciro cyibikoresho bya EPON bigarukira cyane cyane kubiturika bya optique yohereza / kwakira module hamwe na module yibanze yo kugenzura / Chips na E-PON ibiciro bya module bihora bigabanuka kugirango bikemure isoko; ugereranije na xDSL, igiciro kimwe cyinjiza cya PON kiri hejuru, kandi kuri ubu gikoreshwa cyane cyane mubice bishya byubatswe cyangwa byubatswe ahantu huzuye abakoresha. Ethernet ya point-to-point optique irakwiriye gusa kubakiriya ba leta batatanye nabakiriya ba entreprise kubera igiciro cyayo kinini. Gukoresha FTTC + E-PON + LAN cyangwa FTTC + EPON + DSL nigisubizo cyiza cyo kwimuka buhoro buhoro kuri FTTH.
