Cov yam ntxwv ntawm cov khoom
Fiber ntau: G.657A2
FUTONG bending insensitive G.657.A2 ib hom fiber ntau ua raws li G.657.a2 tus qauv pom zoo los ntawm I-TUT B6a2 tus qauv pom zoo los ntawm IEC. Nws muaj qhov zoo tshaj plaws attenuation coefficient, qis dej-peak thiab kev sib kis tau zoo. Nws tuaj yeem xa mus rau hauv OESCL rau tag nrho cov qhab, thiab tag nrho sib xws nrog G.652D network, nyob rau hauv qhov chaw ntawm me me dabtsi yog khoov txoj kab uas hla ntawm cov chaw xaim. Nyob rau tib lub sijhawm, cov khoom siv txheej txheej zoo ua rau nws lub zog qaug zog ntau dua, uas tuaj yeem tiv thaiv nws los ntawm kev tawg thaum lub cable nyob rau hauv ib qho me me dabtsi yog khoov vojvoog ntawm lub sijhawm ntev .Yog li nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm FTTH xaim.
