Will putting couplers in CAT5e lines hamper network speed

We have 40 connections on 2nd floor.  All wires go through the floor into two switches.  

I want to move the switches next to the server and centralized all network equipment.  Currently, the switches are in a "library".  

Can I just put RJ45 jacks on the ends of the existing lines and "extend" the lines using another cable to the patch panel; from the patch panel I would use a patch cord to the switches?  Will this hamper network speed.  

All the runs should be under 295 feet.  

I have a tester and will test one wire but also wanted any comments/concerns.

Thanks,

Brant

Should work fine.... as long as you do not exceed 300ft your ok.  All patch panel's do is similar to a coupler and you can have a number of patches in a row as long as they are all good patches.

It depends on the quality of your terminations.  All terminations will introduce a level of Cross Talk.  If you use quality components and do quality work, it should be OK.  You can't test this with a basic wire tester which does pin outs - you'd need a tester capable of measuring Near End and Far End Cross Talk - NEXT, FEXT.  If you're running standard 10/100 Ethernet you should be OK.  If you're running GigE over copper, you might notice a slight lessening of throughput, assuming you can push a 1000Mb connection near max utilization.

Be sure that your couplers are rated Cat5e. Your wiring is only as good as the lowest-rated component.

if there was a way, i would give all three of you the points...all good answers but just chose first one.

I have one of those real world testers which show line speed and length.

Thanks again!
