Re: [TEKNIK] Lysnet og UTP kabel sammen?

Jeg står for at skulle trække nogle kabler. Hvad siger folk til at trække forsyningspænding til en repeater med i et 230V kabel ved siden af UTP kablet? Jeg ved Cisco forbander det - men det er jo ikke altid lig med virkeligheden....



For en del år siden da UTP kabler endnu var noget nyt - dengang brugte man "gult ethernet kabel", som var på tykkelse med en haveslange - snakkede jeg med nogle folk fra et firma, der kom og installerede UTP-kabler til vores nye netværk.

De fortalte at de lige havde lagt UTP kabler ind på hele Avedøre
værket, som dengang var ved at blive bygget. Det eneste sted de havde
brugt fiber-kabler pga. interferens var i selve turbine-hallen, hvor
kablerne skulle passere hen over de dynamoer, der genererer strømmen.

Så hvis ellers det bliver gjort ordentligt - ikke for lange stykker
usnoet kabel i stik-dåserne, ikke for skarpe knæk på kablerne osv. -
så burde det ikke være noget problem.

Men man skal vist være varsom med at bruge skærmede kabler. Ihvertfald vi skærmen er forbundet i begge ender og de enheder man forbinder ikke har fælles jord. Der er ivertfald en del der fik nogle underlige problemer på soekris's mailingliste
