Uburyo Fibre Optic Reflectors ikoreshwa mugukurikirana PON Network

Muri PON (Passive Optical Network) imiyoboro, cyane cyane murwego rugoye-kugwiza PON ODN (Optical Distribution Network) topologiya, kugenzura byihuse no gusuzuma amakosa ya fibre bitanga ibibazo bikomeye. Nubwo optique ya domeni yerekana (OTDRs) ikoreshwa cyane mubikoresho, rimwe na rimwe ntibabura sensibilité ihagije yo kumenya ibimenyetso byerekana ibimenyetso bya fibre ya ODN cyangwa kumutwe wa ONU. Gushiraho igiciro gito-cyumurongo-uhitamo fibre yerekana fibre kuruhande rwa ONU nigikorwa gisanzwe gifasha gupima neza amaherezo ya endenuation yo gupima optique ihuza.

Imashini ya fibre ikora ikoresheje optique ya fibre optique kugirango igaragaze impanuka ya OTDR igaruka hamwe na 100% byerekana. Hagati aho, imikorere isanzwe yumurambararo wa sisitemu ya optique ya optique (PON) inyura mumashanyarazi hamwe na attenensiya nkeya kuko idahaza fibre ya fibre ya Bragg. Igikorwa cyibanze cyubu buryo ni ukubara neza igihombo cyagarutse kuri buri shami rya ONU ishami ryarangiye mugutahura ibimenyetso byerekana ibimenyetso bya OTDR. Ibi bifasha kumenya niba ihuza ryiza riri hagati ya OLT na ONU rikora bisanzwe. Kubwibyo, igera ku gihe nyacyo cyo kugenzura ingingo zamakosa no kwisuzumisha byihuse.

Mugukoresha byoroshye ibyuma byerekana kugirango tumenye ibice bitandukanye bya ODN, gutahura byihuse, kwimenyekanisha, hamwe nimpamvu zisesengura ryamakosa ya ODN birashobora kugerwaho, kugabanya igihe cyo gukemura amakosa mugihe uzamura imikorere yikizamini hamwe nubwiza bwumurongo. Mubice byambere bitandukanya, fibre yerekana fibre yashyizwe kuruhande rwa ONU yerekana ibibazo mugihe urumuri rwishami rwerekana igihombo cyagarutse cyane ugereranije nubuzima bwiza. Niba amashami ya fibre yose afite ibyuma byerekana icyarimwe kwerekana igihombo cyagarutse, byerekana amakosa muri fibre nyamukuru.

Mugihe cya kabiri cyo gutandukanya ibintu, itandukaniro ryo gutakaza kugaruka rishobora no kugereranywa neza niba amakosa ya attenuation aboneka mugice cyo gukwirakwiza fibre cyangwa igice cya fibre. Haba mubice byambere cyangwa byisumbuyeho gutandukana, bitewe nigabanuka ritunguranye ryimpinga yibitekerezo kumpera yumurongo wikizamini cya OTDR, igihombo cyo gutakaza agaciro kumashami maremare maremare mumurongo wa ODN ntushobora gupimwa neza. Kubwibyo, impinduka murwego rwo kumurika zigomba gupimwa nkibanze ryo gupima amakosa no gusuzuma.

Ibyuma bya fibre optique birashobora kandi koherezwa ahantu hasabwa. Kurugero, kwishyiriraho FBG mbere ya Fibre-Kuri-Murugo (FTTH) cyangwa Fibre-to-the-Building (FTTB) aho winjirira, hanyuma ukagerageza hamwe na OTDR, bituma ugereranya amakuru yikizamini ukoresheje amakuru y'ibanze kugirango umenye imbere / hanze cyangwa kubaka imbere / hanze ya fibre fibre.

Fibre optique yerekana irashobora gushyirwa muburyo bukurikirana kumpera yumukoresha. Kuramba kwabo, kwizerwa gushikamye, kuranga ubushyuhe buke, hamwe nuburyo bworoshye bwo guhuza imiterere ya adapt nimwe mumpamvu ari amahitamo meza ya optique yo guhitamo guhuza imiyoboro ya FTTx. Yiyuantong itanga ibyuma bya fibre optique ya FBG muburyo butandukanye bwo gupakira, harimo amaboko ya plastike, amaboko yicyuma, hamwe ningurube hamwe na SC cyangwa LC.
