Uhlobo:
Gobela Ukungazweli kwimowudi enye yeFayibha ye-Optical (G.657.A1)
Umgangatho:
Ifiber iyahambelana okanye igqithise inkcazo yobugcisa kwi-ITU-T G.657.D / A1.
Uphawu:
Ipropati ephezulu yokuchasana nokugoba;
Ihambelana ngokupheleleyo ne-G.652 i-fiber yemodi enye.Ibhendi epheleleyo (1260 ~ 1626 nm) usasazo;
I-PMD ephantsi yezinga eliphezulu kunye nokuhanjiswa komgama omde.I-micro-bending attenuation ephantsi kakhulu, esebenzayo kuzo zonke iindidi zentambo ye-optical kuquka iiribhoni;
Ipharamitha ephezulu yokulwa nokudinwa iqinisekisa ubomi benkonzo phantsi kweradiyasi encinci yokugoba.
Isicelo:
Zonke ulwakhiwo lwekhebula, i-1260 ~ 1626nm yokuhanjiswa kwebhendi epheleleyo, i-FTTH isantya esiphezulu sokuhamba kwe-optical, intambo ye-optical kwi-radius encinci ye-bend, i-fiber fiber optical encinci kunye nesixhobo, i-L-band.

Ngo-2004, i-GL FIBER yaseka umzi-mveliso wokuvelisa iimveliso zentambo ye-optical, ikakhulu ivelisa intambo yokulahla, intambo yangaphandle yangaphandle, njl.
I-GL Fiber ngoku ineesethi ezili-18 zezixhobo zokufaka imibala, iiseti ezili-10 zezixhobo zokugquma zeplastiki zesibini, iiseti ezili-15 zezixhobo zokujija ze-SZ, iiseti ezili-16 zezixhobo zokugquma, iiseti ezisi-8 zezixhobo zokuvelisa iintambo ze-FTTH, iiseti ezingama-20 zezixhobo zentambo ze-OPGW optical cable, kunye 1 izixhobo ezihambelanayo kunye nezinye izixhobo ezincedisa imveliso.Okwangoku, umthamo wonyaka wemveliso yeentambo ze-optical ufikelela kwi-12 yezigidi ze-core-km (i-avareji yemveliso yemihla ngemihla ye-45,000 yeekhilomitha ezingundoqo kunye neentlobo zeentambo zinokufikelela kwi-1,500 km).Iifektri zethu zinokuvelisa iintlobo ezahlukeneyo zeentambo zangaphakathi nangaphandle (ezifana ne-ADSS, i-GYFTY, i-GYTS, i-GYTA, i-GYFTC8Y, i-micro-cable evuthelwa ngumoya, njl njl.).umthamo wemihla ngemihla wemveliso yeentambo eziqhelekileyo unokufikelela kwi-1500KM / ngosuku, umthamo wemihla ngemihla wemveliso yentambo yokulahla unokufikelela kubuninzi.I-1200km / ngosuku, kunye nomthamo wemveliso yemihla ngemihla ye-OPGW inokufikelela kwi-200KM / ngosuku.
