FTTH yakira neza (CT-2002C)
Incamake
Iki gicuruzwa ni FTTH yakira optique, ikoresheje imbaraga nkeya optique yakira hamwe na optique igenzura tekinoroji ya AGC, ishobora guhaza ibikenerwa bya fibre kugeza murugo, kandi irashobora gukoreshwa ifatanije na ONU cyangwa EOC kugirango igere kumikino itatu. Hano hari WDM, 1550nm ya CATV yerekana ifoto yerekana amashanyarazi hamwe nibisohoka bya RF, 1490/1310 nm Ikimenyetso cya PON kinyura mu buryo butaziguye, gishobora guhura na FTTH imwe ya fibre optique yohereza CATV + XPON.kandi ikubahiriza ibidukikije bya XGSPON,
Ibicuruzwa byegeranye muburyo bworoshye kandi byoroshye kubishyiraho, kandi nibicuruzwa byiza byo kubaka umuyoboro wa kabili TV FTTH.
Ikiranga
> Igikonoshwa cyiza cyane cya plastike hamwe numuriro mwiza wo hejuru.
> Umuyoboro wa RF wuzuye GaAs urusaku ruke amplifier umuzunguruko. Kwakira byibuze ibimenyetso bya digitale ni -18dBm, naho kwakira byibuze ibimenyetso bisa ni -15dBm.
> AGC igenzura urwego ni -2 ~ -14dBm, kandi ibisohoka ntabwo byahindutse. (Urutonde rwa AGC rushobora gutegurwa ukurikije umukoresha).
> Igishushanyo mbonera cyo gukoresha amashanyarazi make, ukoresheje uburyo bunoze bwo guhinduranya amashanyarazi kugirango wizere neza kandi uhamye kumashanyarazi. Imbaraga zikoreshwa mumashini yose ntiziri munsi ya 3W, hamwe numuzingi wo kumenya urumuri.
> Yubatswe muri WDM, menya ubwinjiriro bwa fibre imwe (1490/1310 / 1550nm) gukina gatatu.
> SC / APC cyangwa FC / APC ihuza optique, metric cyangwa santimetero ya RF irahitamo.
> Uburyo bwo gutanga amashanyarazi ya 12V DC yinjira.

Ibibazo
FTTH yakira neza yakira ibibazo bikunze kubazwa
Q1. Niki FTTH yakira?
Igisubizo: FTTH optique yakira ni igikoresho gikoreshwa muri fibre-to-home (FTTH). Yashizweho kugirango yakire ibimenyetso bya optique biva mumiyoboro ya fibre optique no kubihindura mubimenyetso byamashanyarazi kugirango bitunganyirizwe.
Q2. Nigute FTTH optique yakira ikora?
Igisubizo: FTTH optique yakira ikoresha imbaraga nke za optique yakira hamwe na optique yunguka igenzura (AGC). Ikoranabuhanga rya AGC ryemeza ko imbaraga za optique zakiriwe ziguma murwego runaka muguhindura inyungu zabakiriye. Ibi bitanga ibimenyetso byizewe byo kwakira no gukora neza.
Q3. Ni izihe nyungu zo gukoresha FTTH optique yakira?
Igisubizo: Gukoresha FTTH optique yakira bizana inyungu nyinshi kumurongo wa FTTH. Ituma fibre optique yakira neza kandi ikanahindura, igafasha interineti yihuta, TV nziza cyane, hamwe na serivisi zijwi ryumvikana. Byongeye kandi, irashobora guhuzwa hamwe na Optical Network Unit (ONU) cyangwa Ethernet hejuru ya Coax (EOC) kubikorwa bya gatatu-gukina.
Q4. Nibihe bikorwa bya FTTH optique yakira?
Igisubizo: Ibyakirwa bya FTTH bikoreshwa cyane cyane mumiyoboro ya FTTH kugirango uhuze amazu yo guturamo cyangwa ubucuruzi nibikorwa remezo bya fibre optique. Ikora nkigikoresho cyanyuma gifata ibimenyetso bya optique bigenda mumigozi ya fibre optique ikabihindura mubyuma byamashanyarazi bikwiranye na serivisi zitandukanye, nka interineti, televiziyo, nijwi.
Q5. Ese FTTH optique yakira hamwe nibindi bikoresho?
Igisubizo: Yego, FTTH optique yakira irashobora gukoreshwa hamwe na ONU cyangwa EOC kugirango tumenye serivisi eshatu zo gukina. ONU ikora nk'ihuriro rikuru ryo gukwirakwiza interineti, televiziyo n'amajwi mu bibanza, mu gihe imashini ya optique ya FTTH itanga kwakira neza no guhinduranya ibyo bimenyetso. Hamwe na hamwe, bashyigikira guhuza hamwe na serivise zitandukanye muri FTTH.
