G.657A1 Fiber-hal qaab oo qaloocsan

G.657A1 Qallooca aan xasaasi ahayn ee qaab-hal-hab ah Sawirka

Sharaxaad Gaaban:

Badeecadu waxay qabataa tignoolajiyada wax-soo-saarka fiber-ka-horumarsan ee dhammaan-synthetic fiber-ka-horumarsan, kaas oo xakameyn kara OH-ka-koobnaanta usha hore ee fiber-ka-horumarsan ilaa heer aad u hooseeya, sidaa darteed alaabtu waxay leedahay is-barbar-dhigid heersare ah iyo heerka ugu sarreeya ee biyaha, waxqabadka gudbinta oo aad u wanaagsan.Alaabtu waxay xaqiijin kartaa radius yar oo foorarsi ah iyada oo si buuxda ula jaanqaadi karta shabakadda G.652D, sidaas darteed fiberku wuxuu si buuxda u buuxin karaa shuruudaha xargaha ee FTTH.

Tilmaamaha Alaabta

● Wax-soo-saarka attenuation oo aad u wanaagsan iyo biyaha ugu sarreeya.

● "O - E - S - C - L ee dhammaan gudbinta band.

● Lumay laabasho hoose.

● Xoog daal badan.

● Si buuxda ula jaan qaada shabakada G.652D.

Wax soo saarka alaabta

Codsiga Alaabta

1. Ku habboon dhammaan noocyada qaab dhismeedka fiilada fiber optic: nooca tube beam dhexe, lakabka gacanta dabacsan nooca xayiran, nooca qalfoofka, qaab-dhismeedka fiilada fiber optic;

2. Codsiyada fiber optics-ka waxaa ka mid ah: nidaamyada fiber optic-ga ee u baahan khasaare hoose iyo baaxad sare;Waxay si gaar ah ugu habboon tahay MAN fiilada jilicsan ee jilicsan, qalab yar oo fiber optic ah, xirmooyinka fiber optic iyo codsiyada kale ee gaarka ah;

3. Fiberka noocaan ah wuxuu ku habboon yahay O, E, S, C iyo L bands (taas oo ah, laga bilaabo 1260 ilaa 1625nm).Fiber indhaha noocan oo kale ah ayaa si buuxda ula jaan qaada fiber G.652D.Tilmaamaha leexinta luminta iyo booska is haysta ayaa inta badan la hagaajiyay, labadaba si loo hagaajiyo isku xirnaanta;

4. Waxa ay taageeri kartaa in lagu rakibo hababka farsamaynta fiber optic-ga ee dhexroorka yar iyo mugga yar ee xarumaha xafiisyada isgaarsiinta iyo goobaha macaamiisha ee dhismayaasha la deggan yahay iyo guryaha gaarka ah.
