Zoo mechanical thiab kub kev ua haujlwm.
Siab tensile zog. Loose tube tso tseg nrog ib lub raj tshwj xeeb filling compound kom ntseeg tau tias muaj kev tiv thaiv tseem ceeb ntawm fiber ntau.
Xaiv cov khoom siv kho qhov muag zoo tshaj plaws kom ntseeg tau tias cov khoom siv fiber ntau muaj cov khoom sib kis tau zoo. Qhov tshwj xeeb fiber ntau qhov ntev tswj txoj kev muab cov cable nrog cov khoom siv zoo heev thiab ib puag ncig.
Cov khoom siv nruj heev thiab kev tswj xyuas kev lag luam tau lees tias cov cable tuaj yeem ua haujlwm ruaj khov rau ntau tshaj 30 xyoo.
Tag nrho cov ntoo khaub lig-section dej-resistant qauv ua rau lub cable muaj zoo heev noo noo tsis kam.
Qhov tshwj xeeb jelly ntim rau hauv lub raj xoob muab cov fibers nrog kev tiv thaiv tseem ceeb.
Lub steel daim kab xev lub zog optical fiber cable muaj crush kuj.
Daim duab-8 tus qauv txhawb nqa tus kheej muaj lub zog nruj thiab ua kom yooj yim rau kev teeb tsa dav hlau, ua rau cov nqi qis qis.
Lub raj xoob stranding cable core xyuas kom meej tias cov qauv cable ruaj khov.
Lub raj tshwj xeeb filling compound ua kom muaj kev tiv thaiv tseem ceeb ntawm cov fiber ntau thiab ua haujlwm rau dej.
Cov txheej txheej tiv thaiv lub cable los ntawm ultraviolet hluav taws xob.
Qhov me me thiab lub teeb yuag ua rau nws yooj yim rau nteg.

OYI cables yog coiled ntawm bakelite, ntoo, lossis hlau nruas. Thaum lub sij hawm kev thauj mus los, cov cuab yeej tsim nyog yuav tsum tau siv kom tsis txhob ua kom puas lub pob thiab ua rau lawv yooj yim. Cables yuav tsum muaj kev tiv thaiv los ntawm ya raws, khaws cia kom deb ntawm qhov kub thiab txias thiab hluav taws kub, tiv thaiv los ntawm over-bending thiab crushing, thiab tiv thaiv los ntawm mechanical kev nyuaj siab thiab kev puas tsuaj. Nws tsis raug tso cai kom muaj ob qhov ntev ntawm cable hauv ib lub nruas, thiab ob qhov kawg yuav tsum tau muab kaw. Ob qhov kawg yuav tsum tau ntim rau hauv lub nruas, thiab qhov ntev ntawm cable yuav tsum tsis pub tsawg tshaj 3 meters.
Cov xim ntawm cov cim cable yog dawb. Kev luam ntawv yuav tsum tau nqa tawm ntawm qhov sib txawv ntawm 1 meter ntawm sab nraud ntawm lub cable. Cov lus dab neeg rau lub tsho sab nrauv tuaj yeem hloov pauv raws li tus neeg siv qhov kev thov.
Cov ntawv xeem thiab ntawv pov thawj muab.
Yog tias koj tab tom nrhiav kev txhim khu kev qha, kev kub ceev fiber ntau optic cable daws, saib tsis pub dhau OYI. Hu rau peb tam sim no kom pom tias peb tuaj yeem pab koj txuas nrog thiab coj koj txoj kev lag luam mus rau qib tom ntej.
