Hoʻohana maʻamau ʻia nā uwea optical i loko i nā ʻōnaehana cabling i kūkulu ʻia. Ma muli o nā kumu like ʻole e like me ke kūkulu ʻana i ke kaiapuni a me nā kūlana hoʻonohonoho, ua ʻoi aku ka paʻakikī o ka hoʻolālā ʻana o nā kaula optical i loko. He ʻokoʻa nā mea i hoʻohana ʻia no nā fiber optical a me nā kaula, me ka ʻokoʻa o nā ʻano mechanical a me ka optical. Hoʻokomo ʻia nā uwea ʻike o loko maʻamau i nā kaula lālā kumu hoʻokahi, nā uwea hui ʻole, a me nā uwea pūʻolo. I kēia lā, e kālele ana ʻo ONE WORLD i kekahi o nā ʻano maʻamau o nā uwea optical pūʻulu: GJFJV.
GJFJV Uila Optical Loko
1. Hoʻokumu ʻia
ʻO ka hiʻohiʻona maʻamau o ka ʻoihana no nā kelepona optical i loko ʻo GJFJV.
GJ — Hoʻokaʻaʻike i loko o ke kelepona ʻōpika
F — Mea hoʻoikaika kino ʻole
J — Hoʻolālā fiber optical paʻa paʻa
V — Puu Polyvinyl chloride (PVC).
'Ōlelo Aʻo: No ka inoa ʻana o nā mea ʻūhā, ʻo "H" ke ʻano o ka ʻūhi haʻahaʻa halogen-ʻole, a ʻo "U" ʻo ia ka polyurethane sheath.
2. Kiʻi Paʻi Paʻi ʻĀpana Optical Cable
Nā mea hana a me nā hiʻohiʻona
1. Coated Optical Fiber (Hoʻokumu ʻia me ka fiber optical a me ka papa uhi waho)
Hana ʻia ka fiber optical me ka silica material, a ʻo ke anawaena cladding maʻamau ʻo 125 μm. ʻO ke anawaena kumu no ke ʻano hoʻokahi (B1.3) ʻo 8.6-9.5 μm, a no ke ʻano multi-mode (OM1 A1b) he 62.5 μm. ʻO ke anawaena kumu no ka multi-mode OM2 (A1a.1), OM3 (A1a.2), OM4 (A1a.3), a me OM5 (A1a.4) he 50 μm.
I ka wā o ke kaʻina hana kiʻi o ke aniani optical fiber, hoʻohana ʻia kahi papa o ka uhi elastic me ka hoʻohana ʻana i ke kukui ultraviolet e pale ai i ka haumia e ka lepo. Hana ʻia kēia uhi i nā mea e like me ka acrylate, silicone rubber, a me ka nylon.
ʻO ka hana o ka uhi ʻana ʻo ia ka pale ʻana i ka ʻili o ka fiber optical mai ka makū, ke kinoea, a me ka abrasion mechanical, a me ka hoʻomaikaʻi ʻana i ka hana microbend o ka fiber, a laila e hōʻemi ana i nā poho hou aʻe.
Hiki ke kala ʻia ke kala i ka wā e hoʻohana ʻia ai, a pono nā waihoʻoluʻu e kūlike me GB/T 6995.2 (Blue, ʻAlani, ʻōmaʻomaʻo, Brown, Gray, White, Red, Black, Yellow, Purple, Pink, or Cyan Green). Hiki ke waiho ʻole ʻia e like me ke ʻano kūlohelohe.
2. Lapa Hoopaa Paa
Mea Pono: Pili kaiapuni, polyvinyl chloride pale ahi (PVC),uahi haʻahaʻa halogen-ʻole (LSZH) polyolefin, Uea ho'opa'a ahi i helu 'ia e OFNR, uea ho'opa'a ahi i helu 'ia e OFNP.
Hana: Mālama ʻo ia i nā fibers optical, e hōʻoia i ko lākou hiki ke hoʻololi i nā kūlana hoʻonohonoho like ʻole. Hāʻawi ia i ke kūpaʻa ʻana i ka ʻāʻī, ka hoʻopiʻi ʻana, a me ke kuʻi ʻana, a hāʻawi pū i ka wai a me ka wai kū.
E hoʻohana: Hiki ke hoʻopaʻa inoa ʻia ka papa paʻa paʻa no ka ʻike ʻana, me nā code kala e like me nā kūlana GB/T 6995.2. No ka ʻike maʻamau ʻole, hiki ke hoʻohana ʻia nā apo kala a i ʻole nā kiko.
3. Hoʻoikaika i nā ʻāpana
Material:ʻO ke kaula Aramid, he poly(p-phenylene terephthalamide), he ʻano hou o ka fiber synthetic kiʻekiʻe. Loaʻa iā ia nā waiwai maikaʻi loa e like me ka ikaika ultra-kiʻekiʻe, modulus kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka wela, ka waikawa a me ke kūpaʻa alkali, ka māmā, ka insulation, ke kūpaʻa ʻelemakule, a me ke ola lawelawe lōʻihi. Ma nā mahana kiʻekiʻe, mālama ia i ka paʻa, me ka haʻahaʻa haʻahaʻa haʻahaʻa, ka liʻiliʻi creep, a me ka mahana hoʻololi aniani kiʻekiʻe. Hāʻawi pū ia i ke kūpaʻa corrosion kiʻekiʻe a me ka non-conductivity, e hoʻolilo iā ia i mea hoʻoikaika kūpono no nā kaula optical.
Hana: Hoʻopili ʻia ka ʻili Aramid a hoʻopaʻa ʻia i loko o ka hulu uwea e kākoʻo, hoʻonui i ka tensile o ke kaula a me ke kūpaʻa paʻa, ka ikaika mechanical, ke kūpaʻa wela, a me ke kūpaʻa kemika.
ʻO kēia mau hiʻohiʻona e hōʻoia i ka hana o ka hoʻouna ʻana o ke kaula a me ke ola lawelawe. Hoʻohana maʻamau ʻia ʻo Aramid i ka hana ʻana i nā lole pale pale a me nā parachutes ma muli o kona ikaika tensile maikaʻi loa.
4. Pua waho
Mea Pono: Polyolefin (LSZH), polyvinyl chloride (PVC), a i ʻole OFNR/OFNP i helu ʻia i ka lapalapa ahi. Hiki ke hoʻohana ʻia nā mea sheath ʻē aʻe e like me nā koi o ka mea kūʻai aku. Pono e hoʻokō ka polyolefin halogen-free haʻahaʻa i nā kūlana YD/T1113; pono e hoʻokō ka polyvinyl chloride me GB/T8815-2008 no nā mea PVC palupalu; Pono ka polyurethane thermoplastic i nā kūlana YD/T3431-2018 no nā elastomers polyurethane thermoplastic.
Hana: Hāʻawi ka puʻu o waho i ka pale hou no nā fibers optical, e hōʻoia ana hiki iā lākou ke hoʻololi i nā wahi hoʻonohonoho like ʻole. Hāʻawi pū ia i ke kū'ē i ka ʻāʻī, ka hoʻopaʻa ʻana, a me ke kuʻi ʻana, ʻoiai e hāʻawi ana i ka wai a me ka wai. No nā hiʻohiʻona palekana ahi kiʻekiʻe, hoʻohana ʻia nā mea haʻahaʻa haʻahaʻa halogen no ka hoʻomaikaʻi ʻana i ka palekana o ke kaula, pale i nā limahana mai nā kinoea ʻino, uahi, a me nā lapalapa i ka wā o ke ahi.
E hoʻohana: Pono ka waihoʻoluʻu puʻupuʻu e kūlike me nā kūlana GB/T 6995.2. Inā he B1.3-type ka fiber optical, he melemele ka hulu; no ka B6-type, he melemele a ʻōmaʻomaʻo paha ka puʻu; no ka AIa.1-type, pono ia he alani; Pono ke ʻano AIb i hina; A1a.2-type pono he cyan green; a me A1a.3-type pono ke poni.
Nā hiʻohiʻona noiʻi
1. Hoʻohana maʻamau i nā ʻōnaehana kamaʻilio kūloko i loko o nā hale, e like me nā keʻena, nā halemai, nā kula, nā hale kālā, nā hale kūʻai kūʻai, nā kikowaena data, a me nā mea ʻē aʻe. Hoʻohui, hiki ke hoʻohana ʻia nā uwea ʻokoʻa o loko i nā wili pūnaewele home, e like me nā LAN a me nā ʻōnaehana home akamai.
2. Hoʻohana: ʻO nā kaula optical i loko he paʻa, māmā, mālama ākea, a maʻalahi hoʻi e hoʻouka a mālama. Hiki i nā mea hoʻohana ke koho i nā ʻano like ʻole o nā uwea optical i loko e pili ana i nā koi wahi kikoʻī.
Ma nā hale maʻamau a i ʻole nā keʻena keʻena, hiki ke hoʻohana ʻia nā kaula PVC i loko.
Wahi a ke kūlana aupuni GB/T 51348-2019:
①. Nā hale aupuni me ke kiʻekiʻe o 100m a ʻoi aku paha;
②. Nā hale aupuni me ke kiʻekiʻe ma waena o 50m a me 100m a ʻoi aku ka nui ma mua o 100,000㎡;
③. Nā kikowaena ʻikepili o ka papa B a i ʻole;
Pono kēia mau mea e hoʻohana i nā uwea ʻōpika pale ahi me ka helu ahi ʻaʻole haʻahaʻa ma mua o ka haʻahaʻa haʻahaʻa, halogen-noa B1.
Ma ka UL1651 maʻamau i ka US, ʻo ke ʻano kelepona pale ahi kiʻekiʻe loa ʻo OFNP-rated optical cable, i hoʻolālā ʻia e hoʻopau iā ia iho i loko o 5 mika ke ʻike ʻia i kahi lapalapa. Hoʻohui ʻia, ʻaʻole ia e hoʻokuʻu i ka uahi ʻawaʻawa a i ʻole ka mahu, kūpono ia no ka hoʻokomo ʻana i nā ducts ventilation a i ʻole nā ʻōnaehana hoʻihoʻi ea i hoʻohana ʻia i nā lako HVAC.
