what can be the longest distance for a single mics copper run that I can achieve and what category cable should i use?

Max distance for a continous copper run

300 metres on 24 gauge wire but you can extend that a couple of ways.
1. piggyback a SAP power supply at the phone end (max length 1200 metres on 24 gauge wire).
2. or use higher gauge wire or double up on the pairs. max loop resistance is 64 ohms.
Category nothing will work. Actually the lower the category the better. There is less copper per foot in Cat 3 than in Cat 5 so you can stretch your length further.

I am sorry when I meat a single run I was really talking about several DN's sets on a single cable run.
I was looking at using one of these to extend several DN's to another building via fiber
Do you have any experience with this type of equipment?

I ran a test last night. I took a few box of cat6 that I had around they all had 824 feet left total 2472 continuous feet. I splices each box together and test a M7310 set as I went along.
I was able to get the set to function properly until I then added about about 800 feet with some Cat-5. The set still functioned properly but I got a hum on the line.
It is very interesting that you said the less copper I use the better and that cat 3 will do better than cat6. Is this because there is less volume of copper so less voltage used?
Also, do you know why I started hearing a hum?
I have seen posts on here that claim they have reliability reached 3000 feet.

The unused pairs act like an antenna to pick up electronic noise. If you ground the unused pairs I'd bet the hum would go away.

The more copper per foot, the more resistance per foot, the more voltage drop there will be at the far end. When it comes to copper less is more. 24 gauge copper is 0.02567 ohms per foot. According to Nortel spec, when you hit 64 ohms trouble begins.
Get rid of the hum by as Brian said ground the unused pairs or use them all.

Thanks! I will try again tonight.
In your experience what is the longest distance you have been able to install a stable connection for a mics dn set? This cable i am going to install will be 100 pairs direct buriel.

To many and or buts depend on how far you can stretch.
Just use Marv's first post as a reference and use a PS as required....which by the way can go beside the phone or in the closet of it's building.

Well this site has about 50 sets at the remote locations so that is going to cause me to use a lot of SAPS.
One SAPS can power 3 phones or 2 KLM's

Then try a few MCK Nortel Norstar Modular EXTender (500-2170-000)

I'm a little confused about the extenders. Will this device extend an entire 0 x 16 module? Or just me the cob for service?

Can I nit-pick here? Your statement is correct as to wire gauge, where 24 is thinner than 22 is thinner than 16 etc., but smaller gauge numbers = thicker wire = LESS resistance per foot.
You need heavier/thicker/lower-gauge wire (or several conductors paralleled) for a longer run.

I've seen those MCK Nortel Norstar Modular EXTender (500-2170-000) set up and they seem to work great, I've not set one up myself but the one I saw was running on fibre end to end.
I always thought the maximum distance on copper for a phone was about 2000 feet

Agree. Thicker gauge wire = less resistance.

Regarding the MCK Nortel Norstar Modular EXTender (500-2170-000)when you mean each pair are you referring to each fiber pair or each pair of MCK extenders one on both ends.
How are they connected, are they simply connected to a to a fiber port on the MICS and then a short fiber cable to the LOCAL extender and then does that have a second port that the LONG fiber run plugs into? At the REMOTE site does the LONG fiber run plug in toa port and then the 0x16 plug into the other port then out of the 0x16 via a 5 pair AMP toa 66 block?
IS there any special software that is needed for is this plug and play?
Thanks

Isn't that what I said. By less is more I meant less resistance is more distance.

Marv, what's confusing from your post is, "The more copper per foot, the more resistance per foot," when it should be more copper = less resistance. I'm sure that's what you meant.

I have only worked with fiber on the MICs side so I have one more question.
Ate the connectors at the end of the fiber runs the same the one used for my MICS fiber runs? The little white plugs that are used to plug into the fiber cards and the various modules i.e. 0x16, NAM, etc.
