Please log in for more thread options 50-pair CAT5E backbone cable has recently became available from Hitachi Cable Manchester ( http://www.hcm.hitachi.com/productportal.htm ) 100-pair is still not available, if it ever will. Don't go crazy on super-multipair CAT5E cables though. Use bundles of separate 4-pair cables any time you can. The issue of alien crosstalk (cross-talk between cables or between 4-pair groups with regard to multipair cables) has only been first addressed couple years ago in relation to CAT6 cables, and nobody actually knows how this affects CAT5E cables. I have a feeling no manufacturer is in a position to spend time/money of such advanced research on lesser grade cable. With that said, you can be sure alien crosstalk does affect CAT5E cables as well, we just don't know how much. -- Dmitri Abaimov, RCDD http://www.cabling-design.com Cabling Forum, color codes, pinouts and other useful resources for premises cabling users and pros http://www.cabling-design.com/homecabling Residential Cabling Guide ------------------------------------- ##-----------------------------------------------## Article posted with Cabling-Design.com Newsgroup Archive http://www.cabling-design.com/forums no-spam read and post WWW interface to your favorite newsgroup - comp.dcom.cabling - 690 messages and counting! ##-----------------------------------------------## | |||||||||||||||||||

I guess, the wrap plastic is not plenum rated. -- Dmitri Abaimov, RCDD http://www.cabling-design.com Cabling Forum, color codes, pinouts and other useful resources for premises cabling users and pros http://www.cabling-design.com/homecabling Residential Cabling Guide ------------------------------------- ##-----------------------------------------------## Article posted with Cabling-Design.com Newsgroup Archive http://www.cabling-design.com/forums no-spam read and post WWW interface to your favorite newsgroup - comp.dcom.cabling - 692 messages and counting! ##-----------------------------------------------## | |||||||||||||||||||
