Cat 5 / Cat 5e / Cat 6 ?

Postby eg2kiwi » Sun Feb 22, 2009 7:29 pm


At the moment my router is hooked up with Cat 5e cable going to the computer and Cat 5 cable going to the PS3.
Should I change this? It plays fine but what would be better?

You dont tell us if you have a Gigabit (Gb) networking card in your PC or if the router supports Gb. or what distances between the equipent you have.

Short answer : NO

Broadcam NetXtreme 57 Gigabit Controller .... 50 ft away.... one thing I noticed since I had my ps3 via wireless it buffered movies and stuff fine from the ps3 store.... but now since I have it wired it lags a little.... could I have a messed up cable?

for gigabit under 300' length use cat6, be sure to use the T568B termination standard on each end.

For more info check out wikipedia on the cat6 standard, and also to review the TIA/EIA-568-B termination standard. It pretty much sums it up.

You might also want to check if your switch supports jumbo frames.

(some people say cat5e is fine for gigabit at home, but I'd upgrade to cat6 regardless)

Technically, the 568A standard is the suggested termination in all new applications. The 568B termination is the older standard.

As long as you choose one standard and make all your connectors the same, there should be no difference in network performance.

Cat5e cable fine at gigabit as it is 1/3 the price but care is needed when laying and terminating.

I am using a Netgear 108-T 8 port gigabit switch located in the center of the house.
A 48 port Cat5e patch panel allows me to patch to various (18 so far) Cat5e cables (5 - 25m in length) around the house.

Using the network diagnostics tools supplied with either the Intel or Broadcom drivers, I have verified I am getting excellent connectivity. Using the diagnostics cable length 'measurement', I get the correct length.

Cat5e Installation tips:
1. When laying the cables, ensure they never get 'kinked'. A single bend less than 50mm diameter may be enough to make the cable useless for gigabit speeds. Cut it either side of the kink and use the bits somewhere else.
2. Never pull the cable 'hard', it will damage the cable. Prepare cable runs before you lay the cable. I found plastic downpipes cut in half allowed the cables to slide easily.
3. Use solid core cable for all fixed wiring.
4. Take care making the Cat5e RJ45 socket terminations correctly. Ideally the bared pairs should be as short as possible and keep the same 'pair twist' ratio as the orignal cable.
5. You may find making RJ45 socket ternimations easier if you buy Cat6 sockets. They are normally better designed. The ones I used were easier to terminate and probably gave better performance.
6. The NZ telecom wiring guidelines recommend 568B as it ties in with the phone wiring colours. I understand other countries recommend 568A. Either way, use the same throughout and label the main patch panel with your choice.
