expertec Posted February 20, 2006 Report Share Posted February 20, 2006 Hey guys,I'm sure this has been posted before, and I'm sure I used to know, but I forgot. :rolleyes:What is the maximum length... before it degrades or summat? of a cat5 network cable?I think maybe it was 100 metres? 100 feet? I dunno.TIA anyway. :) Quote Link to comment Share on other sites More sharing options...
Hex Posted February 20, 2006 Report Share Posted February 20, 2006 After 100FT of cable i think the cable degrades by about 1DB Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted February 21, 2006 Report Share Posted February 21, 2006 100 Meters max. for 10 and 100baseT (Cat 5 or better Ethernet) cabling. Quote Link to comment Share on other sites More sharing options...
Belatucadrus Posted February 21, 2006 Report Share Posted February 21, 2006 Remembering that cheap cable with bad or non existent shielding could also suffer from interference as well as signal attenuation. Quote Link to comment Share on other sites More sharing options...
expertec Posted February 21, 2006 Author Report Share Posted February 21, 2006 100 Meters max. for 10 and 100baseT (Cat 5 or better Ethernet) cabling.Good good... I should be fine then. Cheers. :)Remembering that cheap cable with bad or non existent shielding could also suffer from interference as well as signal attenuation.Good point, I will consider that when I purchase any cable.Thanks! :) Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted February 21, 2006 Report Share Posted February 21, 2006 Cat 5, 5e, or 6 is generally Unshielded Twisted Pair (UTP) cable, so the 'shielding' comes from the twists in the wire, not from physical shielding, but it's still susceptible to crush damage and short circuiting if the thin insulation between cable pairs becomes damaged. Of course, it's best to run it at least a few feet away from potential sources of interference like electric motors, power cables, light fixtures, etc. if possible. Make sure you get plenum grade cable if you're going in plenum areas, or if your building code requires it if you're running cable through a building. Plenum areas are places where air circulates, like the space between a suspended ceiling and the actual roof.You're getting a lot of information from your simple question! :) Quote Link to comment Share on other sites More sharing options...
Belatucadrus Posted February 23, 2006 Report Share Posted February 23, 2006 so the 'shielding' comes from the twists in the wire, not from physical shieldingtrue enough for general application, but there are occasions where shielded cable is necessary, usually in cabinets or areas of high radio interference.
