Zoo hnub rau txhua tus!
Tsab xov xwm no yuav tham txog lub network cable (Ethernet cable, los yog nkawm twist, kom ntau hu nws), ua tsaug uas lub koos pis tawj nrog rau Internet, tsim kom tau ib lub tsev hauv zos, Internet telephony, thiab lwm yam.
Feem ntau, qhov sib txuas sib txuas network hauv khw yog muag hauv metres thiab tsis muaj kev sib txuas ntawm nws qhov xaus (plugs thiab RJ-45 connectors uas txuas rau lub network card ntawm lub computer, router, modem, thiab lwm yam khoom siv. Ib qho txuas zoo ib yam nyob hauv daim duab saib ua ntej ntawm sab laug.). Nyob rau hauv tsab ntawv no kuv xav qhia koj yuav ua li cas rau kev sib txuas lus xws li cable yog koj xav tsim kom muaj ib qho chaw hauv zos hauv tsev (zoo, lossis, piv txwv, hloov lub computer txuas nrog Internet los ntawm ib chav mus rau lwm tus). Ntxiv thiab, yog tias koj lub network disappears thiab cov cable yog kho, nws zoo nkaus li, Kuv xav kom koj siv lub sijhawm thiab rov txuas rau lub network cable.
Nco ntsoov! Los ntawm txoj kev, nyob rau hauv lub khw muaj twb twb crimped cables nrog tag nrho cov connectors. Muaj tseeb tiag, lawv yog tus qauv ntev: 2m., 3m., 5m., 7m. (m - metres). Tsis tas li ntawd, nco ntsoov hais tias qhov crimped cable yog teeb meem los ntawm ib chav mus rau lwm tus - i.e. thaum nws tsim nyog los thawb nws los ntawm ib lub qhov nyob hauv phab ntsa / kev faib, thiab lwm yam ... Koj tuaj yeem tsis ua lub qhov loj, thiab tus connector yuav tsis haum ntawm lub qhov me me. Yog li no, qhov no, kuv xav kom ncab cov kab ua ntej thiab tom qab ntawd muab hlob.
Koj yuav ua haujlwm dabtsi?
1. Network cable (tseem hu ua nkawm twisted, Ethernet cable, thiab lwm yam). Muag rau hauv metres, koj tuaj yeem yuav luag txhua cov duab (tsawg kawg rau kev xav tau hauv tsev koj yuav pom tsis muaj teeb meem ntawm tej lub kiab khw). Lub screenshot hauv qab no qhia tau hais tias qhov kab no zoo li cas.

Crimping lub network cable nrog tongs (crimper)
Qhov kev xaiv no yooj yim dua thiab sai, yog li kuv mam li pib nrog nws. Tom qab ntawd, kuv yuav hais ob peb lo lus hais txog tias qhov no yuav ua li cas nrog ib tus pa luam yeeb dav hlau.
1) Pruning
Lub network cable yog: ib yam khoom khoob khawm, tom qab uas muaj plaub khi ntawm cov xov hlau nyias, uas muaj lwm txoj kev tiv thaiv (ntau xim, uas tau qhia nyob rau theem kawg ntawm tsab xov xwm).
Yog li, thawj zaug uas koj yuav tsum tau txiav lub plhaub (tiv thaiv lub hnab), koj tuaj yeem tam sim ntawd los ntawm 3-4 cm. Yog li ntawd, nws yuav yooj yim dua mus muab cov kab hluav taws tso rau hauv qhov kev txiav txim kom yog. Los ntawm txoj kev, nws yog yooj yim ua nrog ticks (crimper), tab sis ib txhia xav siv ib tug riam dog dig los yog txiab. Nyob rau hauv cov hauv paus ntsiab lus, lawv tsis hais txhua yam ntawm no, vim nws yooj yim dua rau leej twg - nws tsuas yog ib qho tseem ceeb uas tsis yog ua kom puas hlau khi ntawm lub plhaub.
Lub plhaub yog raug tshem tawm ntawm lub cable cable 3-4 cm.
2) Kev tiv thaivcap
Ntxiv mus, ntxig rau lub hau kev tiv thaiv mus rau hauv lub network cable, mam li ua nws - nws yuav tsis tshua phim. Los ntawm txoj kev, ntau tus neeg tsis quav ntsej cov khwb no (thiab los ntawm txoj kev, dhau lawm). Nws yuav pab kom tsis txhob khoov tsis ruaj ntawm kab ntawv, tsim ib qho "hnov qab plhaub" (thiaj li hais tau lus).

3) Kev faib khoom ntawm qhov thaiv thiab kev xaiv ntawm thaj tsam
Tom qab ntawd faib cov thaiv nyob rau hauv qhov kev txiav txim nyob rau hauv qhov koj xav tau, nyob ntawm xaiv lub tswvyim (qhov no yog tham saum toj no nyob rau hauv tsab xov xwm). Tom qab muab cov xov hlau faib raws li cov tswv yim xav, ua kom lawv nrog cov pliers txog li 1 cm (Koj tuaj yeem txiav lawv nrog txiab, yog tias koj tsis ntshai los txeeb lawv :)).
4) Muab qhov thaiv hlua khi rau hauv qhov txuas
Tom ntej no koj yuav tsum tau muab cov hlua txuas nruab rau hauv lub RJ45 connector. Tus screenshot hauv qab no qhia tau tias yuav ua li cas.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias yog cov xov hlau tsis muaj teeb meem txaus - lawv yuav tawm ntawm lub RJ45 connector, uas yog yam khoom uas tsis zoo - txhua yam kev hloov me ntsis uas koj kov lub xov tooj tuaj yeem ua rau koj lub network puas thiab tawg tau qhov txuas.
Yuav ua li cas txuas mus rau cable nrog RJ45: txoj cai thiab tsis ncaj ncees lawm kev xaiv.
5) Crimp
Tom qab eco, maj mam muab qhov txuas rau hauv clamp (crimper) thiab nyem rau lawv. Tom qab ntawd, peb lub network cable yog crimped thiab npaj txhij mus. Tus txheej txheem nws tus kheej yog yooj yim heev thiab ceev, tsis muaj dab tsi tshwj xeeb los tawm tswv yim rau ntawm no ...

Ntsia Hlau
Tom qab kho lub xov hlau 8, koj yuav tsum txhim kho lub cable nws tus kheej (ntxias uas tiv thaiv cov 8 "leeg"). Qhov no yog qhov tsim nyog kom thaum twg lub cable poob qhov tseeb (piv txwv li, nws yog kov thaum nws raug rho tawm) - tsis muaj kev sib txuas, kom cov 8 leeg tsis ya tawm ntawm lawv cov nyob.
Qhov no tsuas yog ua tiav: kho qhov RJ45 connector rau ntawm lub rooj, thiab los saum toj no thawb nws nrog tib lub tshuab ntswj.
compression braid
Yog li ntawd, koj tau txais kev ruaj ntseg thiab kev ua zoo sib xws. Koj tuaj yeem txuas ib lub xov tooj zoo sib xws rau koj lub PC thiab txaus siab rau lub network :).
Los ntawm txoj kev, tsab xov xwm ntawm lub ntsiab lus ntawm teeb rooj sib tham hauv zos:
- tsim ib qhov chaw sib txuas ntawm 2 lub tshuab computer.
Qhov ntawd yog txhua yam. Hmoov zoo!
