Cable Debate a runaway success
The packed out event saw five top cabling experts debate three hot topics in cabling
Network Middle East held its very successful debut Great Cable Debate event in June.
The event saw five top international cabling gurus discuss three contentious topics in the structured cabling arena, with the help of an expert moderator.
The hotly contended topics were discussed in front of a full house of end-users and saw strong audience participation.
The first topic that was discussed was ‘Is alien crosstalk testing needed for Cat 6A cabling?’ This topic saw the experts express widely differing views on the necessity and benefits of Cat 6A alien crosstalk testing, with the discussion becoming quite heated.
While Alan Flatman, a cabling expert on several standards bodies, and cabling manufacturers Nexans said that alien crosstalk testing is necessary, except on shielded systems, cabling manufacturers R&M, Siemon and CommScope agreed that if a Cat 6A unshielded cable system is completely tuned and ‘met by design’, ie the cable system is lab tested to meet an alien crosstalk requirement of more than 10% on a voltage basis, then alien crosstalk testing is unnecessary. With that percentage of headroom over the recommended standard there is enough space for alien crosstalk resulting from poor installation practices to be absorbed, according to Valerie Maguire, cabling standards expert and director of standards and technology at cabling manufacturer Siemon.
All parties agreed that alien crosstalk testing was unnecessary on shielded systems.
