ʻAno:
Bend Insensitive Single-mode Optical Fiber (G.657.B3)
Kūlana:
Hoʻokō a ʻoi paha ka fiber i nā kikoʻī loea ma ITU-T G.657.A1/A2/B2/B3.
Hiʻona:
ʻO ka radius piko liʻiliʻi he 7.5mm, ʻoi aku ka maikaʻi o ka waiwai anti-bending;
Hoʻopili piha me ka fiber G.652 hoʻokahi-mode fiber. Hoʻouna i ka hui piha (1260~1626nm);
PMD haʻahaʻa no ka hoʻouna ʻana i ka bit-rate kiʻekiʻe a me ka lōʻihi. ʻO ka attenuation micro-bending haʻahaʻa haʻahaʻa loa, pili i nā ʻano uwea optical āpau me nā lipine;
ʻO ka palena anti-fatigue kiʻekiʻe e hōʻoiaʻiʻo i ke ola lawelawe ma lalo o ka radius liʻiliʻi liʻiliʻi.
Noi:
ʻO nā hana uwea āpau, 1260~1626nm ka hoʻouna ʻana i ka band piha, FTTH kiʻekiʻe kiʻekiʻe o ka hoʻokele ʻana i ka optical, ke kaula uila ma ka radius liʻiliʻi liʻiliʻi, ka liʻiliʻi liʻiliʻi optical fiber cable a me ka mea hana.

Hale Hana Uila Optical
I ka makahiki 2004, ua hoʻokumu ʻo GL FIBER i ka hale hana no ka hana ʻana i nā huahana cable optical, ka mea nui e hana ana i ke kaula hāʻule, waho optical cable, etc.
Loaʻa iā GL Fiber i kēia manawa he 18 mau ʻāpana kala, 10 mau ʻāpana o nā mea hoʻonaninani kiʻekiʻe kiʻekiʻe, 15 sets o SZ layer twisting equipments, 16 sets of sheathing equipments, 8 sets of FTTH drop cable production equipments, 20 sets of OPGW optical cable equipments, and 1 nā lako hana like a me nā mea hana kōkua ʻē aʻe he nui.
