Ib qho tsim nyog muaj Ethernet cable yog qhov tshwm sim ntawm kev sib koom ua haujlwm ntawm nws cov khoom sib txawv. Cov khoom tseem ceeb muaj xws li:
1. Tus neeg xyuas pib: feem ntau yog ua los ntawm cov pa oxygen-dawb tooj liab kom ntseeg tau tias kev ua tau zoo thiab cov teeb liab kis tau zoo. Tus neeg xyuas pib lub thickness kuj cuam tshuam rau kev sib kis thiab kev ua haujlwm.
2. Rwb thaiv tsev thiab twisting: Txhua tus neeg xyuas pib yog them nrog ib txheej rwb thaiv tsev, thiab ob lub insulated conductors yog twisted ua ke nrog lub suab meej. Qhov kev sib tw - khub qauv no yog lub hauv paus rau kev tshem tawm cov khoom siv hluav taws xob sab nraud.
3.Shielding Layer: Qhov no yog lub plawv ntawm kev lag luam cables. Cov qauv uas muaj xws li:
* Aluminium Foil Shielding: Npog ib lossis tag nrho cov xov hlau, feem ntau tiv taus siab - zaus cuam tshuam.
* Braided Mesh Shielding: Feem ntau yog ua los ntawm tin -plated tooj liab mesh, muab qhov zoo tsawg- kev cuam tshuam kev cuam tshuam thiab kev tiv thaiv txhua yam.
* Combined Shielding: Xws li txhuas ntawv nyiaj ntxiv rau braided mesh, muab kev tiv thaiv kev tiv thaiv.
4. Sheath: Lub plhaub tiv thaiv sab nraud, kev xaiv cov khoom tseem ceeb heev. Cov ntaub ntawv muaj xws li PVC thiab polyurethane, uas muaj cov khoom xws li hnav tsis kam, UV tsis kam, roj tsis kam, thiab nplaim hluav taws. Hauv cov xwm txheej uas xav tau kev tiv thaiv kev siv tshuab siab heev, ib txheej armor ntxiv rau hauv lub hnab.
