He aha ka ʻokoʻa ma waena o 250μm loose-tube uwea a me 900μm tight-tube uwea?
ʻO 250µm loose-tube cable a me 900µm tight-tube cable he ʻelua ʻano ʻano o nā kaula like ʻole me ke anawaena like, ka uhi ʻana, a me ka uhi.Eia nō naʻe, aia nō nā ʻokoʻa ma waena o nā mea ʻelua, i hoʻopili ʻia i ke ʻano, ka hana, nā pōmaikaʻi, nā hemahema, a me nā mea ʻē aʻe, ʻo ia ka mea e ʻokoʻa ai nā mea ʻelua i ka noi.
I ka hihia o ka pulupulu manuahi, ua hoʻokomo ʻia i loko o kahi paipu semi-rigid, e ʻae ana i ke kaula e hoʻolōʻihi ʻia me ka ʻole o ke kikoo ʻana i ka fiber ponoʻī.ʻO ka 250μm loose tube fiber i haku ʻia me ka core, 125μm cladding a me 250μm coating.ʻO ka mea maʻamau, ʻo ka helu o nā cores i loko o ka 250μm loose-tube optical cable aia ma waena o 6 a me 144. Koe wale no ka 6-core loose-tube optical cable, ʻo nā kaula optical ʻē aʻe i haku ʻia me nā cores 12 ma ke ʻano kumu.
ʻOkoʻa i ka ʻōnaehana loose-tube i ʻōlelo ʻia ma luna nei, ʻo ka 900 μm tight-buffered optical fiber he paʻa paʻa paʻa i hoʻohui ʻia me ka 250 μm loose-tube optical fiber structure, hiki ke pāʻani i kahi hana pale.ʻO kahi fiber 900μm paʻa paʻa paʻa i loko o kahi kumu, kahi pale 125μm, kahi uhi 250μm (ʻo ia ka plastik palupalu), a me kahi kapa (he plastic paʻakikī).Ma waena o lākou, ʻo ka papa uhi a me ka ʻaʻahu ʻaʻahu e kōkua i ka hoʻokaʻawale ʻana i ka makū mai ke komo ʻana i ke kumu fiber, a hiki ke pale i ka pilikia hoʻolaha nui i hoʻokumu ʻia e ke kuʻi ʻana a i ʻole ke kaomi ʻana i ka wā e waiho ʻia ai ke kaula optical i lalo o ka wai.ʻO ka helu o nā cores i loko o kahi kaula paʻa paʻa 900μm ma waena o 2 a me 144, a ʻo kahi kaula paʻa paʻa me ka helu nui o nā cores i haku ʻia he 6 a i ʻole 12 cores ma ke ʻano kumu.
Ma muli o nā ʻano hana like ʻole o ka 250μm loose tube cable a me ka 900μm tight tube cable, ʻokoʻa ka hoʻohana ʻana o nā mea ʻelua.He kūpono ka 250μm loose tube cable no nā kaiapuni ʻino a hoʻohana nui ʻia ma waho.Ke hoʻohālikelikeʻia me ka 900μm tight-buffer optical cable,ʻo ka 250μm loose-buffer optical cable he kiʻekiʻe ka ikaika o ka tensile, ke kūpaʻa o ka wai a me ke kūpaʻa wela kiʻekiʻe, a ua kūpono i nā wahi me nā hoʻololi wela a me ka haʻahaʻa kiʻekiʻe.Eia naʻe, inā ʻoi aku ka lōʻihi, e huki ia i ke kumu mai ka gel.Eia kekahi, ʻaʻole i koho maikaʻi ʻo 250µm i ka uwea loose-tube i ka wā e pono ai ke ala ʻana a puni nā piko he nui.
