according to specification ethernet cable signal will start degrade at abt 100m

best is to keep a single pull to less than 90 meters for best signal the shorter the better

but also depends on quality of the cable... but never go more than 100m

also rmbr cat6 cable is stiffer than cat5, so when the "contractors" pulling the cable through the conduit make sure it doesn't overly bend the cables like how the garden hose bent until the water flow kena block, cause u will "hurt/luka" the cable

since already pulling the lan cable.. always rmbr to pull extra for back up...

seems cheaper to get it in malaysia if you have the right contacts or

contractor doing structured cabling... for IT companies...
