Tsav los ntawm kev nrawm ntawm kev txawj ntse thiab qhov xav tau siab rau kev siv dav dav hauv cov chaw khaws ntaub ntawv, txawm hais tias kho qhov muag fiber tau ua tiav muaj kev sib koom ua ke loj ntawm cov kab ke vim yog qhov zoo ntawm kev sib kis tau zoo thiab bandwidth loj, cov tooj liab tseem yog qhov tseem ceeb hauv txoj haujlwm ntawm cov chaw zov me nyuam. Tshwj xeeb hauv kev siv ib puag ncig tshwj xeeb xws li lub suab xa mus thiab lub zog xa khoom, lub luag haujlwm ntawm tooj liab tooj liab yog kab hluav taws xob uas tsis tuaj yeem hloov pauv tau los ntawm fiber ntau.
Hauv kev txuas kab rov tav tsis pub dhau 100 metres, fiber ntau kho qhov muag tsis zoo rau tooj liab cable hais txog kev saib xyuas, tus nqi, thiab txuas. Cov tub ntxhais ntawm cov kho qhov muag fiber yog ib hom tshwj xeeb ntawm cov iav fiber, uas yog qhov tawg yooj yim dua li tooj liab hauv cov tooj liab tooj liab. Hauv kev thaiv thiab tom qab kho, yog tias cov khoom siv kho qhov muag tsis tau them nyiaj rau, nws yuav yooj yim puas thiab nws cov nqi yuav nce ntxiv; Los ntawm cov xwm txheej kev lag luam tam sim no, txawm hais tias tus nqi ntawm fiber ntau qhov muag tau raug txo qis, nws tseem siab dua tus nqi ntawm tooj liab cable feem ntau; yog li ntawd, piv rau cov kho qhov muag fiber, tooj liab txuas xov tooj thiab kho tau yooj yim dua thiab raug nqi.
Hauv daim ntawv thov siv hluav taws xob xws li lub suab xa xov thiab xa xov mus rau wireless, thiab POE cov tshuab siv hluav taws xob, cov khoom siv hluav taws xob tsis tuaj yeem hloov cov tooj liab tooj liab.
Vim tias tooj liab tooj liab sib txawv ntawm cov kab hluav taws xob hauv qhov uas lawv xa cov ntaub ntawv los ntawm hluav taws xob pulses thiab tuaj yeem txhawb lub suab qhia. Yog li ntawd, cov tooj liab tooj liab tuaj yeem siv rau kev xa suab, tab sis cov fibers kho qhov muag tsis tuaj yeem ua. Txij li cov iav siv hauv fiber ntau kho qhov muag tsis tuaj yeem siv hluav taws xob, thiab tooj liab hauv kab tooj liab tuaj yeem ua hluav taws xob, tooj liab tooj liab tuaj yeem muab hluav taws xob thaum ua cov ntaub ntawv sib txuas, yog li nws tau siv dav hauv kev siv wireless, POE lub zog muab hluav taws xob, thiab LED zog system, thiab lwm yam.
Ib qho ntxiv, qhov txuas txuas txuas txuas txuas txuas (MPTL) tau pom zoo tias yog qhov kev xaiv rau txuas cov khoom siv hauv TIA-568.2-D tus qauv. Qhov kev txav no yuav txhawb txoj kev loj hlob ntawm RJ45 daim ntawv thov tooj liab tooj liab, tshwj xeeb tshaj yog hauv kev saib xyuas lub cev siv IP koob yees duab. Nyob rau tib lub sijhawm, 28AWG cov lus qhia tshwj xeeb network dhia tau ntxiv rau cov ntawv txuas ntxiv ntawm qhov kev qhia tshwj xeeb no, thiab kev qhia me me ntawm cov tooj liab tooj liab yuav pab ua kom cua nkag thiab siv qhov chaw, yog li nws tuaj yeem tsim kho hauv cov ntawv thov ceev.
