ITU-G.657B3 Ib qho yooj yim khoov fiber ntau
Qhib Whats App
Hom:
Khoov Insensitive Ib hom Optical Fiber (G.657.B3)
Txheem:
Cov fiber ntau ua raws los yog tshaj cov kev qhia tshwj xeeb hauv ITU-T G.657.A1/A2/B2/B3.
Feature:
Yam tsawg kawg khoov vojvoog 7.5mm, superior tiv thaiv dabtsi yog khoov;
Tau tshaj G.652 ib hom fiber ntau.Tag nrho band (1260 ~ 1626nm) kis tau tus mob;
Tsawg PMD rau siab me ntsis-tus nqi thiab kev sib kis ntev.Tsis tshua muaj micro-bending attenuation, muaj feem xyuam rau txhua hom kho qhov muag cable nrog rau ribbons;
Siab tiv thaiv kev qaug zog ua kom muaj kev pab cuam lub neej nyob rau hauv me me dabtsi yog khoov vojvoog.
Daim ntawv thov:
Tag nrho cov kev siv cable, 1260 ~ 1626nm tag nrho cov kev sib kis tau zoo, FTTH kev kub ceev kho qhov muag, kho qhov muag cable hauv me me khoov vojvoog, me me optical fiber cable thiab ntaus ntawv.
