Uhlobo:
I-Bend Engazweli Yemodi Eyodwa I-Optical Fiber (G.657.B3)
Okujwayelekile:
Ifayibha ithobelana noma idlule izicaciso zobuchwepheshe ku-ITU-T G.657.A1/A2/B2/B3.
Isici:
Ubuncane bendawo yokugoba engu-7.5mm, indawo ephakeme evimbela ukugoba;
Ihambisana ngokugcwele ne-G.652 yemodi eyodwa fibre. Ukuhanjiswa kwebhendi egcwele (1260~1626nm);
I-PMD ephansi yokudluliselwa kwebanga eliphezulu kanye nebanga elide. I-attenuation ephansi kakhulu yokugoba okuncane, esebenza kuzo zonke izinhlobo zekhebula le-optical kuhlanganise namaribhoni;
Ipharamitha ephezulu yokulwa nokukhathala iqinisekisa impilo yesevisi ngaphansi kwerediyasi encane yokugoba.
Isicelo:
Konke ukwakhiwa kwekhebula, 1260~1626nm ukudluliselwa kwebhendi egcwele, umzila we-FTTH obona ngesivinini esiphezulu, ikhebuli yokubona ku-radius encane yokugoba, ikhebuli yefiber ebonakalayo enosayizi omncane kanye nedivayisi.

I-Optical Cable Factory
Ngo-2004, i-GL FIBER yasungula ifekthri ukuze ikhiqize imikhiqizo yekhebula elikhanyayo, ikakhulukazi ikhiqiza ikhebula lokudonsa, ikhebula lokukhanya langaphandle, njll.
I-GL Fiber manje inamasethi angu-18 emishini yokufaka imibala, amasethi angu-10 ezinto zokumboza zepulasitiki zesibili, amasethi angu-15 emishini yokusonta ungqimba lwe-SZ, amasethi angu-16 emishini yokushela, amasethi angu-8 emishini yokukhiqiza amakhebula e-FTTH drop, amasethi angu-20 emishini yentambo ye-optical ye-OPGW, kanye Imishini ehambisanayo engu-1 Kanye nezinye izinto eziningi ezisizayo zokukhiqiza. Njengamanje, umthamo wonyaka wokukhiqiza wezintambo ezibonakalayo ufinyelela ku-12 million core-km (isilinganiso somthamo wansuku zonke wokukhiqiza wama-45,000 core km kanye nezinhlobo zezintambo zingafinyelela ku-1,500 km). Izimboni zethu zingakhiqiza izinhlobo ezahlukene zezintambo zangaphakathi nezangaphandle (njenge-ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, ikhebula elincane eliphephetha umoya, njll.). umthamo wokukhiqiza wansuku zonke wezintambo ezivamile ungafinyelela ku-1500KM/ngosuku, umthamo wokukhiqiza wansuku zonke wekhebula lokudonsa ungafinyelela ubuningi. 1200km/ngosuku, futhi umthamo wansuku zonke wokukhiqiza we-OPGW ungafinyelela ku-200KM/ngosuku.
