FTTH DROP CABLE DEAD END

FTTH (Fiber - Rau - Lub - Tsev) poob cable tuag - kawg yog ib qho tseem ceeb nyob rau hauv lub FTTH network. Nws lub luag haujlwm tseem ceeb yog txhawm rau tshem tawm qhov poob cable kom ruaj ntseg, tsim kom muaj kev sib raug zoo ntawm cable thiab tus neeg siv lub davhlau ya nyob twg, xws li Optical Network Unit (ONU). Los ntawm khov kho qhov poob cable ntawm lub sijhawm no, nws tiv thaiv kev cuam tshuam kev sib txuas los ntawm sab nraud quab yuam xws li rub, vibration, lossis ib puag ncig yam. Qhov no ua kom ntseeg tau tias cov neeg siv tuaj yeem txaus siab rau qhov zoo - zoo fiber ntau - kev pabcuam kev sib txuas lus optic.
Jera Line tsim tus txiv neej tuag kawg grips los txuas cov cable sib txawv los ntawm mus txog 6.5mm poob cables.

Cov yam ntxwv tseem ceeb:
1. Kev sib txuas ruaj ntseg

FTTH nco cable tuag - kawg yog nruab nrog cable - ruaj cov khoom ua los ntawm high - zog hlau los yog ruaj engineering yas. Cov Cheebtsam no tau tsim tshwj xeeb grooves lossis clamps uas nruj nreem kaw thiab tuav lub tsho sab nraud ntawm txoj hlua khi. Lawv tuaj yeem tiv taus lub zog tensile tseem ceeb, tiv thaiv kom tsis txhob muaj cov kab hluav taws xob tawm ntawm qhov tuag - kawg, ua kom muaj kev sib txuas ruaj khov thiab ntev - ntev.
2. Ntau hom kev sib txuas
Lub fiber optic splicing mechanism muab kev txhawb nqa tseem ceeb rau kev sib txuas ntawm qhov poob cable thiab cov khoom siv kho qhov muag hauv cov neeg siv khoom. Muaj ob txoj kev sib txuas: fusion splicing thiab mechanical (txias) splicing. Fusion splicing tuaj yeem muab qhov qis - poob thiab txhim khu kev qha zoo. Cold splicing, ntawm qhov tod tes, yog tus neeg siv ntau dua - tus phooj ywg thiab tsim nyog rau kev nrawm ntawm - qhov chaw teeb tsa.
3. Kev tiv thaiv zoo
Nws los nrog cov ntaub thaiv tiv thaiv uas tsis muaj dej, plua plav - pov thawj, thiab UV - tiv taus, ua los ntawm qib siab yas lossis cov ntaub ntawv sib xyaw. Cov ntaub thaiv npog no tsis tsuas yog tiv thaiv cov kab mob xws li dej thiab plua plav los ntawm kev nkag mus thiab ua rau kev sib txuas ntawm fiber ntau optic tab sis kuj tiv thaiv UV hluav taws xob, txuas ntxiv lub neej ntawm cov neeg tuag - chav tsev kawg. Nyob rau hauv ib puag ncig sab nraum zoov, qee cov ntaub thaiv npog kuj tau tsim los nrog kev cuam tshuam - cov yam ntxwv tiv thaiv kom tiv taus lub cev puas tsuaj.
4. Kev txhim kho yooj yim
Kev xaiv ntawm qhov chaw installation yog hloov tau yooj yim. Nws tuaj yeem ntsia tau rau sab hauv ntawm tus neeg siv lub tsev sab nrauv phab ntsa, ze rau sab hauv tsev tsis muaj zog - lub thawv tam sim no. Qhov chaw no yog qhov yooj yim rau kev xaim hluav taws xob sab hauv tsev thiab txo qhov kev pheej hmoo ntawm cov kab hluav taws xob raug cuam tshuam rau sab nraum zoov, txo qhov muaj peev xwm ntawm kev puas tsuaj. Lub caij no, cov txheej txheem kev teeb tsa tau ua tiav hauv cov kauj ruam meej, ua kom yooj yim rau cov neeg ua haujlwm tsim ua haujlwm.
5. Kev tu yooj yim
Nws yog qhov yooj yim rau kev kuaj xyuas thiab tu. Cov kev kuaj xyuas niaj hnub tuaj yeem ua tiav los ntawm kev tshuaj xyuas seb lub cable puas ruaj ntseg yog xoob thiab seb qhov thaiv thaiv puas muaj qhov tawg lossis qhib. Cov cuab yeej siv kho qhov muag fiber ntau xws li Lub Sijhawm Optical - Domain Reflectometer (OTDR) kuj tuaj yeem siv los ntsuas qhov kev sib txuas ntawm fiber ntau optic poob. Thaum kuaj pom muaj teeb meem, cov khoom siv cuam tshuam tuaj yeem kho lossis hloov pauv raws sijhawm kom ntseeg tau qhov txuas ntxiv ntawm cov neeg siv kev sib txuas lus.
