CAT-6 -Return Loss failed (RL and RL @ Remote)

Emiljo — Mon, 29 Aug 2011 13:59:58 +0000

Hi i have one situation that for me is complecated.I run cat6 utp netwok cable, When I connect each end of the cable to a Fluke DSP-4000 & DTX-1800 Network Analyzer it tells me that Return Loss failed (RL and RL @ Remote). I check details on the analyzer it says that pair 3,6 failed 4,5 failed and the others passed. All the cables are inside of metal gutter. i have 2 question: 1-What kind of problem can give Return Loss failed (RL and RL @ Remote) ? 2-Just i want to be sure that this network will work in 1000 mb.

Thanks in advance Emiljo

What type of cable is suitable for an RS-485 interface?

NetworkingATE — Wed, 26 Aug 2009 15:23:13 +0000

This is a serial specification and as such is going to be dependent partially on electronics. Cat 6 is better balanced than Ccat 5, and I am a big fan of shielded systems for a variety of reasons. I would suggest, however, that you discuss this with the active supplier. Cabling is backwards- compatible so the higher category of cable you install the more future- proofed you are as in it won’t have to be replaced. If you need to send over the active specs, I can have a further look.

how does channel length affect patch cord length?

I need to install a 10/100 base Ethernet switch into a rather small cabinet. I read in a previous discussion that the minimum length for a CAT5e patch cable is 2.5m, which will make the install look untidy. If I use a CAT6 or CAT6a cable what will the minimum length have to be?

What to do about cabling long distances and signal strength fading?

NetworkingATE — Wed, 10 Dec 2008 19:52:21 +0000

I made a connection using Cat 6 SYSTIMAX cable from the server switch to the next repeater, which is 85 meters – and then to the next point it is 50 meters and then 50, then 50. The problem is the signal strength is not that strong and its on and off. What do you advise me to do? Thank you.

How to derive bandwidth from the frequency of Cat6 cables

NetworkingATE — Fri, 10 Oct 2008 17:12:36 +0000

How do you derive bandwidth (bits per second) from the frequency of Cat6 cable (250MHz for example)? It is known that Cat6 can carry up to 1 Gbps.

Why should you install Cat6 over Cat5E cables?

NetworkingATE — Thu, 22 May 2008 21:23:09 +0000

If CAT 5E is rated for 1 Gbit and a standard CAT 6 (not 6A) will only support 10 Gbit to 40 or 50 meters, then what is the purpose of installing Cat6 instead of Cat5E?
