ʻO waho FTTH Kākoʻo pilikino Bow-Type Drop Cable

ʻO Aipu-waton GJYXCH a me GJYXFCH uwea optical he FTTH kakaka-ʻano hāʻule waho. Aia ka uwea optical 1 ~ 4 silica optical fibers me ka uhi, hiki iā G657A1 a i ʻole G652D. E hoʻohana ʻia nā fiber optical i hana ʻia e ka hoʻolālā like, nā mea a me nā kaʻina hana i loko o ka pūʻulu o nā huahana like, a e kau ʻia nā fibers optical i waenakonu o ke kaula optical. Hiki ke waihoʻoluʻu i ka papa uhi uhi fiber optical. ʻO ka waihoʻoluʻu o ka papa waihoʻoluʻu he uliuli, ʻalani, ʻōmaʻomaʻo, ʻeleʻele, hina, keʻokeʻo, ʻulaʻula, ʻeleʻele, melemele, poni, ʻulaʻula a cyan paha e like me GB 6995.2, a hiki i ka fiber hoʻokahi ke kala maoli. ʻO ke ʻano o ka uhi ʻana, ka pae nānā ikaika o ka fiber, ke anawaena o ke kahua a me nā ʻāpana nui, ka lōʻihi o ka nalu ʻoki ʻia a me ka nalo ʻana o ka fiber optical mode hoʻokahi i hoʻohana ʻia no ka hoʻopili ʻana e hoʻokō me nā ʻōlelo ma ka Papa 1, 2 a me 3 ma lalo nei. ʻO ka lālā ikaika i ka uwea hāʻule optical hiki ke lilo i ka uea kuhiliʻole ikaika kiʻekiʻe a i ʻole ke kila phosphated, a i ʻole he lālā hoʻoikaika kino ʻole o ka uea polyester aramid a i ʻole nā ​​puʻupuʻu fiber kūpono ʻē aʻe, e loaʻa i ka modulus o Young's modulus a me ka elastic strain range. ʻO nā lālā ikaika o ka uwea optical he 2 like a like me ke ʻano o ke kaula optical. A mānoanoa kila uea e kau ana uea ma kaʻaoʻao lawe i ka hana paʻa ponoʻī. No ka PVC sheathed optical uwea, ka mea sheath pono e hoʻokō i nā mea o ka hr-70 "70 ℃ soft sheath grade soft PVC plastic" ma GB/T 8815; No ka polyethylene sheathed flame cable optical, pono e hoʻokō ka mea sheath me nā ʻōlelo o YD/T 1113; He palahalaha a pahee ka ili o ka pu, aole ikeia na mawae, na ohu, na lua one a me na hemahema e ae ma kona pauku. ʻEleʻele maʻamau ka waihoʻoluʻu sheath, hiki ke hana ʻia e like me nā kala ʻē aʻe i koi ʻia e nā mea hoʻohana. E kaha mau ʻia ka uwea optical ma ka ʻili o ka puʻu, ʻaʻole e hoʻopilikia i ka hana o ke kaula optical, a ʻo ka mamao ma waena o nā wahi hoʻomaka o nā hōʻailona pili ʻaʻole e ʻoi aku ma mua o 500m.
