Rau cov neeg xa khoom siv hluav taws xob, cov neeg faib khoom, thiab cov neeg cog lus tsim kho, kev khaws cov lus qhia tseeb ntawm lub khoos phis tawj (cov ntaub ntawv) thiab xov tooj (lub suab) phab ntsa yog qhov tseem ceeb rau kev ua tau raws li cov qauv hluav taws xob niaj hnub. Txhawm rau pab peb cov neeg koom tes thoob ntiaj teb ua kom zoo dua lawv cov khoom muag thiab kev twv nqi, peb pab neeg engineering tau muab cov lus qhia tseem ceeb no ntawm RJ45 thiab RJ11 socket technologies.
1. Cov Qhov (Sockets) Hauv Computer (RJ45): Xaiv Pawg Ethernet Uas Yog
Feem ntau hu ua network, LAN, lossis Ethernet outlets, cov computer sockets sivRJ45 chaw nres nkoj(8-pin connectors). Qhov kev ua tau zoo thiab qhov siab tshaj plaws ntawm lub qhov (RJ45 socket) nyob ntawm seb pawg (Cat) ntawm nws cov xov tooj sab hauv:
- Qeb 5e (Cat5e):Txhawb nqa qhov ceev txog li 1 Gbps (Gigabit Ethernet) ntawm 100 MHz. Txawm hais tias nws pheej yig heev, nws tab tom dhau los ua cov thev naus laus zis qub thiab zoo tshaj plaws rau kev kho dua tshiab uas xav tau nyiaj txiag.
- Qeb 6 (Cat6):Tus qauv thoob ntiaj teb rau kev tsim kho vaj tse thiab kev lag luam. Nws txhawb nqa qhov ceev txog li 10 Gbps ntawm qhov deb txog li 55 meters (ua haujlwm ntawm 250 MHz). Muab kev txo qis crosstalk zoo heev, Cat6 yog qhov pib pom zoo heev rau txhua qhov kev tsim kho tshiab.
- Qeb 6A (Cat6A):Nws muaj ob npaug ntawm bandwidth (500 MHz) thiab xa tag nrho 10 Gbps txog li 100 meters. Tsim los nrog kev tiv thaiv siab heev kom tshem tawm kev cuam tshuam hluav taws xob (EMI), Cat6A yog qhov kev xaiv zoo tshaj plaws rau cov chaw khaws ntaub ntawv, cov chaw ua haujlwm ntse, thiab cov haujlwm nyob hauv tsev zoo.
2. Qhov (Sockets) Xov Tooj (RJ11): Tus Qauv Suab Classic
Txawm hais tias muaj kev nce ntxiv ntawm cov tes hauj lwm mobile, kev sib txuas lus hauv av tseem ceeb heev rau cov modems DSL hauv chaw ua haujlwm hauv tsev, cov tshuab fax analog, cov intercoms hauv tsev so, thiab cov txheej txheem thaub qab thaum muaj xwm txheej ceev. Cov chaw xa xov tooj siv cov chaw nres nkoj RJ11 (feem ntau yog 4-pin lossis 6-pin connectors):
- Tus Qauv CAT3:Feem ntau cov qhov (sockets) xov tooj RJ11 txheem yog tsim los rau CAT3 (Qeb 3). Ua haujlwm ntawm 16 MHz, CAT3 yog tus nqi tsim nyog heev thiab zoo meej rau kev xa xov tooj analog huv si, tsis muaj kev cuam tshuam.
- Kev Teeb tsa Pin:Cov neeg xa khoom tuaj feem ntau tuaj yeem nrhiav tau cov no hauv 2-pin (4P2C) kev teeb tsa rau cov xov tooj hauv tsev ib kab yooj yim, lossis 4-pin (4P4C) kev teeb tsa rau cov kab ua lag luam ob kab.
3. Yav Tom Ntej: Cov Kev Daws Teeb Meem "Ib Txoj Kab Hlau" Modular
Hauv cov qauv tsev niaj hnub no, ciam teb ib txwm muaj ntawm cov xov tooj thiab cov xov hlau network tsis meej. Cov kws tshaj lij hauv kev lag luam tab tom siv ob qho tseem ceeb:
- RJ45 rau Lub Suab (Kev kho dua tshiab):Vim tias lub qhov ntsaws xov tooj RJ11 tuaj yeem haum rau hauv thiab txuas nrog lub qhov (socket) RJ45 network loj dua, ntau qhov project niaj hnub siv cov khoom siv Cat5e lossis Cat6 zoo rau ob qho tib si cov ntaub ntawv thiab cov xov tooj. Qhov no ua kom yooj yim rau kev txuas hluav taws xob thiab tso cai rau lub qhov (socket) hloov tau yooj yim los ntawm kab xov tooj mus rau qhov chaw nres nkoj internet ceev ceev los ntawm kev hloov lub vaj huam sib luag hauv chav server.
- Cov Phaj Modular Multi-Gang:Yuav kom txuag tau qhov chaw ntawm phab ntsa thiab lub sijhawm teeb tsa, cov phaj sib xyaw ua ke uas muab ib lub qhov rooj RJ45 thiab ib lub qhov rooj RJ11 ua ib chav tsev tau dhau los ua pawg muag khoom zoo tshaj plaws thoob ntiaj teb.
Ntawm Liper, peb muab kev daws teeb meem hluav taws xob thiab teeb pom kev zoo uas sib xyaw ua ke, ua tau zoo heev. Nrog rau peb cov koob teeb pom kev zoo LED uas tau ntawv pov thawj, peb muab ntau yam kev hloov pauv phab ntsa, RJ45 cov khoom sib txuas, thiab RJ11 (CAT3) lub qhov (sockets) xov tooj uas tsim los ua kom tau raws li cov qauv thoob ntiaj teb.
