Efaneti chingwe: kufotokoza, cholinga, mitundu ya mankhwala

Pakuti unsembe Intaneti kompyuta ntchito Efaneti chingwe wapadera (LAN-chingwe). Pali mitundu yambiri yaikulu ya mawaya: awiri opiringizika, coaxial, ndi CHIKWANGWANI chamawonedwe. Yoyamba akuti ndi yotsika mtengo ndi zophweka kwambiri, choncho ntchito oposa 90 peresenti Intaneti onse m'deralo.

Mitundu ya nsapato zopotoka

Izi chingwe Efaneti Ndi ambiri ndi otchuka. Amakhala ndi ochititsa mkuwa eyiti amene matanthauzo zapiringizana. The kutchinjiriza kugwiritsidwa ntchito ndi kusintha PVC. Pali mitundu yambiri ya nsapato zopotoka, kusiyana mtundu uliwonse zina zodzitetezera kapena kupanda kwake. Ntchito zoteteza angachichite aluminum zojambulazo momuzungulira mawaya, kapena mkuwa kuluka lirilonse. Komanso, pali njira kuphatikiza chitetezo. Efaneti isagwe chingwe zambiri kugonjetsedwa ndi kuwasokoneza kunja, koma, motero, ali mtengo kwambiri. Palinso mitundu yambiri ya zopotoka-awiri, amene anasonyeza ndi yotani "CA" imene ndiyo gulu la waya. Pali mitundu isanu ndi iwiri ya chizindikiro ichi. The apamwamba gulu chiwerengero kwambiri, mphamvu chingwe ndi mwachitsanzo amagwiritsa ochititsa kwambiri. Choncho, wachisanu ndi chiwiri gulu la zopotoka awiri (lomaliza tsiku) limakupatsani popereka mauthenga imathamanga 40 Gbit / s. Kupereka liwiro amenewa popanda kukhota mbendera, gulu lirilonse la ochititsa mu chingwe ayenera khalidwe impedance 100 ohms.

Efaneti coaxial chingwe

Mtundu uwu wa waya wapangidwa ndi wochititsa ndi chophimba kukhala olamulira wamba kasinthasintha. chingwe ndi zizindikiro wochititsa, ndi insulator, PVC m'chimake, mkuwa kapena zotayidwa kuluka. Lero, mtundu wa waya ntchito ngati wochititsa kwa mlongoti lapansi. Intaneti Local, bungwe pa zingwe coaxial, pafupifupi aliyense. Waya ambiri ndi khalidwe impedance wa ohms 50 - maukonde kompyuta - ndi 77 ohms - mufotokoze TV chizindikiro. The pazipita deta kufala mphamvu ndi 10 Mbit / s. Komanso, ndi kosathandiza, monga imavuta kwambiri kukonza malo zowonongeka, amene kenako kumabweretsa awiri.

CHIKWANGWANI kuwala

zingwe Efaneti izi yodziwika ndi attenuation otsika, ngakhale pamene kupatsira deta pa mtunda wautali, iwo sali pansi kusokonezedwa. Komanso, CHIKWANGWANI kuwala ali mkulu liwiro yomasulira. Kwa kukonza pansi review, chingwe pamafunika zida apadera ndi zipangizo, ndi kufunika kugwirizana zida kawalidwe. Mtundu sikawirikawiri ntchito yomanga Intaneti mu nyumba kapena ofesi, chifukwa, kuwonjezera zida chipangizo, iwo ali mtengo m'malo okwezeka.

Efaneti-chingwe pinout

Standard awiri anayi zopotoka awiri kumanga Intaneti m'dera crimped cholumikizira RJ 45 mtundu. kugwirizana chiwembu ali motere: zoyera wobiriwira, zobiriwira, woyera, lalanje, buluu, yoyera, buluu, lalanje, zofiirira ndi woyera ndi waya bulauni. Crimping ziwembu akusiyana malingana ndi cholinga cha mizere wolumikiza, umisiri ndi mfundo zakayendesedwe zambiri. Nthawi zina ntchito patsogolo ndi chigamulocho (mtanda) crimp cholumikizira.
