After reading this thread, I went to Sim Lim Tower (LHS Electronics - Level 2) to purchase Belden Cat 6 cables today.
LHS is an interesting shop because they don't display their cables in pre-cut lengths in packets like other shops. Their cables are stored in reels and they cut the cables according to customer's length, grade and crimp requirements. I waited about 45 min as they had to cope with existing orders (there were two technicians in their stations). I noticed some of the cable lengths of other customers were much longer than mine, confirming that they have regular clientele. There were also 2 or 3 other customers who dropped by just to buy fixed cable lengths for their home internet setup. They knew exactly what they wanted and seemed quite pro (compared to us newbies).
I went upstairs and downstairs and checked out other SLT shops' Cat 6 cables. Most of them sold unbranded cables, for about the same or higher price than LHS. One shop sold TE Cat 6 for about 300% higher price than LHS. It seemed like inconsistent pricing and quality so I'm sure that some people who bought unbranded cables would be disappointed when they went home.
LHS charged me $1 per metre and $5 for crimping the ends of each cable.
NOW FOR THE RESULTS
I tested out the Belden Cat 6 this afternoon with the following results:
1.
Wifi (60Mbps)
2.
Cat 5e (no name brand, 1m long)
(180Mbps)
3.
Cat 6 (Belden brand, 10m long)
(224Mbps)
Hope this helps.
