網絡綜合線4+2是(shi)網絡監(jian)控(kong)布線系(xi)統中常用(yong)的一種線，網絡綜合線4+2的特點是可(ke)以一次性穿管，節約空間(jian)，成本和時間(jian)。網絡(luo)綜合線4+2一般在出廠前已經對干擾等做過測試，只要不超(chao)過標準的傳輸距離就可以(yi)了。
       網線(xian)(xian)+2芯電源線(xian)(xian)電源線(xian)(xian)連接監(jian)控網絡的(de)(de)傳(chuan)輸距離最好不要超過60米(mi)。如果走強電的(de)(de)話(hua)，網線(xian)(xian)是可以(yi)傳(chuan)輸到120米(mi)左(zuo)右(you)，但(dan)作為(wei)弱電傳(chuan)輸，走集中供電時，電源線(xian)(xian)只能(neng)通(tong)過60米(mi)。建議選擇(ze)無氧銅材質的(de)(de)綜合線(xian)(xian)。
    網線(xian)(xian)(xian)(xian)+2芯(xin)(xin)電(dian)源線(xian)(xian)(xian)(xian)分為4芯(xin)(xin)網線(xian)(xian)(xian)(xian)+2芯(xin)(xin)電(dian)源線(xian)(xian)(xian)(xian)和8 芯(xin)(xin)網線(xian)(xian)(xian)(xian)+2芯(xin)(xin)電(dian)源線(xian)(xian)(xian)(xian)，接(jie)頭主要要考慮的(de)是網線(xian)(xian)(xian)(xian)的(de)接(jie)法。實際上(shang)，網線(xian)(xian)(xian)(xian)+2芯(xin)(xin)電(dian)源線(xian)(xian)(xian)(xian)接(jie)入(ru)水晶頭的(de)線(xian)(xian)(xian)(xian)序實際上(shang)和普通網線(xian)(xian)(xian)(xian)都是按照國際接(jie)法.
    T568A/T568B。在布線的時候要統(tong)一一種線序，減(jian)少復(fu)查時出現的麻(ma)煩(fan)。T568B線序：1.橙(cheng)白(bai)2.橙(cheng) 3.綠白(bai) 4.藍 5.藍白(bai) 6.綠 7.棕(zong)白(bai) 8.棕(zong)（水晶頭銅片向上，從左到右）。
    芯(xin)網線(xian)(xian)(xian)(xian)+2芯(xin)電(dian)源線(xian)(xian)(xian)(xian)只(zhi)有網線(xian)(xian)(xian)(xian)只(zhi)有4條線(xian)(xian)(xian)(xian)，對應著接線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)序：1.橙白2.橙，3.綠(lv)(lv)白，6.綠(lv)(lv)。百(bai)兆網(wang)絡(luo)(luo)下且(qie)距離不長的(de)情(qing)況下，都可以使用4條(tiao)芯(xin)來(lai)傳輸網(wang)絡(luo)(luo)。8芯(xin)網線+2芯(xin)電源線的線序就按(an)照標準線序來(lai)連接。1.橙白2.橙 3.綠白 4.藍 5.藍白 6.綠 7.棕白 8.棕
