No ka hōʻoia ʻana i ka pale ʻana o ke kaula optical mai ka mechanical, thermal, chemical, a me ka moisture e pili ana i ka pōʻino, pono e hoʻolako ʻia me kahi puʻupuʻu a i ʻole nā papa o waho. Hoʻonui maikaʻi kēia mau ana i ke ola lawelawe o nā fiber optical.
ʻO nā pū i hoʻohana maʻamau ʻia i loko o nā uwea optical, ʻo ia ka A-sheaths (aluminum-polyethylene bonded sheaths), S-sheaths (steel-polyethylene bonded sheaths), a me ka polyethylene sheaths. No nā uwea ʻōpika wai hohonu, hoʻohana maʻamau ʻia nā sheaths sila i hoʻopaʻa ʻia.
Hana ʻia ka polyethylene sheaths mai ka laina haʻahaʻa haʻahaʻa, medium-density, a i ʻolemea polyethylene ʻeleʻele kiʻekiʻe, e like me ke kūlana GB/T15065. Pono ka ʻili o ka uhi polyethylene ʻeleʻele e maʻemaʻe a ʻaʻahu ʻole, ʻaʻohe ʻōhū i ʻike ʻia, nā pinhole, a i ʻole nā māwae. Ke hoʻohana ʻia ma ke ʻano he puʻu waho, ʻo ka mānoanoa nominal he 2.0 mm, me ka liʻiliʻi o ka mānoanoa o 1.6 mm, a ʻo ka awelika mānoanoa o kēlā me kēia ʻāpana ʻaʻole e emi iho ma mua o 1.8 mm. Pono nā waiwai mechanical a me ke kino o ka puʻu i nā koi i kuhikuhi ʻia ma YD/T907-1997, Papa 4.
Aia ka A-sheath i kahi papa pale pale i hana ʻia me ka ʻōwili lōʻihi a uhi ʻialipine alumini i uhi ʻia i ka plastik, hui pū me ka ʻeleʻele polyethylene sheath extruded. Hoʻopaʻa ka polyethylene sheath me ka lipine composite a me nā ʻaoʻao o luna o ka lipine, hiki ke hoʻoikaika hou ʻia me ka pipili inā pono. ʻAʻole pono e emi iho ka laulā o ka lipine composite ma lalo o 6 mm, a i ʻole no nā cores uwea me nā anawaena ma lalo o 9.5 mm, ʻaʻole ia e emi iho ma mua o 20% o ke anapuni o ke kumu. ʻO ka mānoanoa inoa o ka polyethylene sheath he 1.8 mm, me ka liʻiliʻi o ka mānoanoa o 1.5 mm, a me ka mānoanoa awelika ʻaʻole i emi iho ma mua o 1.6 mm. No ka ʻano 53 papa waho, ʻo ka mānoanoa inoa he 1.0 mm, ʻo ka mānoanoa liʻiliʻi he 0.8 mm, a ʻo ka mānoanoa awelika he 0.9 mm. Pono ka lipine alumini-plastic composite e kū i ke kūlana YD/T723.2, me ka lipine alumini he 0.20 mm a i ʻole 0.15 mm (ka liʻiliʻi 0.14 mm) a me ka mānoanoa kiʻi ʻoniʻoni o 0.05 mm.
Ua ʻae ʻia kekahi mau hui lipine composite i ka wā o ka hana ʻana i ke kaula, inā ʻaʻole i emi ka mamao o ka hui ma lalo o 350 m. Pono kēia mau hui e hōʻoia i ka hoʻomau uila a hoʻihoʻi hou i ka papa plastic composite. ʻAʻole pono e emi ka ikaika ma ka hui ma lalo o 80% o ka ikaika o ka lipine kumu.
Ke hoʻohana nei ka S-sheath i kahi papa pale makū i hana ʻia me ka ʻōwili lōʻihi a uhi ʻia.lipine kila i uhi ʻia i ka plastik, hui pū me ka ʻeleʻele polyethylene sheath extruded. Hoʻopaʻa ʻia ka polyethylene sheath me ka lipine composite a me nā ʻaoʻao overlapping o ka lipine, hiki ke hoʻoikaika ʻia me ka pipili inā pono. Pono ka lipine composite corrugated e like me ke apo ma hope o ka wahī ʻana. ʻAʻole pono e emi iho ka laulā ma lalo o 6 mm, a i ʻole no nā cores uwea me nā anawaena ma lalo o 9.5 mm, ʻaʻole ia e emi iho ma mua o 20% o ke anapuni o ke kumu. ʻO ka mānoanoa inoa o ka polyethylene sheath he 1.8 mm, me ka liʻiliʻi o ka mānoanoa o 1.5 mm, a me ka mānoanoa awelika ʻaʻole i emi iho ma mua o 1.6 mm. Pono ka lipine hoʻopili kila-plastic composite e hoʻokō i ka maʻamau YD/T723.3, me ka lipine kila me ka mānoanoa inoa o 0.15 mm (ka liʻiliʻi 0.13 mm) a me ka mānoanoa kiʻi ʻoniʻoni o 0.05 mm.
Ua ʻae ʻia nā hui lipine composite i ka wā o ka hana ʻana i ke kaula, me ka palena liʻiliʻi o 350 m. Pono e hui pū ʻia ka lipine kila, e hōʻoia ana i ka hoʻomau ʻana o ka uila a me ka hoʻihoʻi ʻana i ka papa hana. 'A'ole e emi ka ikaika ma ka hui 'ana ma lalo o 80% o ka ikaika o ka lipine hui kumu.
ʻO ka lipine aluminika, ka lipine kila, a me nā ʻāpana pale kila i hoʻohana ʻia no nā pale wai e mālama i ka hoʻomau uila ma ka lōʻihi o ke kaula. No nā pūpū i hoʻopaʻa ʻia (me nā ʻāpana waho Type 53), ʻo ka ikaika ʻili ma waena o ka alumini a i ʻole ka lipine kila a me ka polyethylene sheath, a me ka ikaika o ka ʻili ʻana ma waena o nā ʻaoʻao overlapping o ka alumini a i ʻole ka lipine kila, ʻaʻole pono e emi ma lalo o 1.4 N/mm. Eia nō naʻe, i ka wā e hoʻohana ʻia ai kahi mea pale wai a i ʻole ka uhi ʻana ma lalo o ka alumini a i ʻole ka lipine kila, ʻaʻole koi ʻia ka ikaika peeling ma nā ʻaoʻao overlapping.
Mālama kēia ʻōnaehana pale piha i ka lōʻihi a me ka hilinaʻi o nā kaula optical i nā ʻano like ʻole, e hoʻokō pono ana i nā pono o nā ʻōnaehana kamaʻilio hou.
