Kugereranya kwa PON eshanu zishingiye 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) kuri sisitemu yo guteranya ahantu hatuwe cyangwa inyubako, hanyuma igahuzwa na koridor ikoresheje fibre optique (0,95km), hanyuma ikanyuzwa kumukoresha ukoresheje umugozi wa 5 (0.05 km).Kubarwa ukurikije icyitegererezo cyabakoresha 500 (utarinze gusuzuma ikiguzi cyicyumba cyakagari), harasabwa byibuze icyerekezo kimwe cyo guhuza ibyambu 24 hamwe na 21 ya 24 ya koridor.Mugukoresha nyabyo, urwego rwinyongera rwo guhinduranya muri rusange rwongeyeho.Nubwo umubare wimyanya yose wiyongera, ikoreshwa ryikiguzi cyo hasi cyibiciro bya koridor igabanya igiciro cyose.

FTTH

Tekereza gushyira OLT ku biro bikuru, fibre imwe ya optique (4km) mucyumba cya mudasobwa yo hagati, mucyumba cya mudasobwa yo hagati ukoresheje 1: 4 optique (0.8km) kuri koridor, na optique ya 1: 8 gutandukanya (0.2km) muri koridor ukoresha terminal.Kubarwa ukurikije icyitegererezo cy-abakoresha 500 (utitaye ku giciro cyicyumba cyakagari): Igiciro cyibikoresho bya OLT gitangwa ku gipimo cy’abakoresha 500, bisaba ibyambu 16 byose bya OLT.

FTTC + EPON + LAN

Tekereza kandi gushyira OLT ku 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 ONU ifite imikorere yo guhinduranya Layeri 2.Urebye ko ONU ifite ibyambu 16 FE, ni ukuvuga ko buri ONU ishobora kugera kubakoresha 16, ibarwa ukurikije urugero rwabakoresha 500.

FTTC + EPON + ADSL / ADSL2 +

Kubisabwa bimwe bya DSLAM kumanuka, tekereza gushyira OLT ku biro bikuru, hamwe na fibre imwe (5km) kuva ku biro byanyuma bya BAS kugera ku biro bikuru bikuru, no ku biro rusange birangira, inyura muri optique ya 1: 8. gutandukanya (4km) kuri ONU mucyumba cya mudasobwa ya selile.ONU ihujwe neza na DSLAM binyuze muri interineti ya FE, 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) muguhuriza hamwe kwabaturage cyangwa inyubako, hanyuma igahita yoherezwa kubakoresha kurangiza binyuze muri fibre optique (1km).Kubarwa ukurikije icyitegererezo cyabakoresha 500 (utarinze gusuzuma ikiguzi cyicyumba cyakagari), harasabwa byibura 21 24-ibyambu byo guteranya ibyambu, kandi 21 kuri kilometero 4 za fibre optique ya fibre optique ishyirwa mubyumba bya mudasobwa bikuru bikuru bikusanyirizwa hamwe. Guhindura muri selire.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.
