Cable splicing 1

[fs483]

I have read many threads on this forum regarding splicing and I myself don't like it. However, rerunning 50 drops at over a 100$ per drop and adding another 150 new drops (also at over a 100$ per drop) is extremely costly. Our cabling contractor said Nordx, well Belden, has a LEGAL splicing device and can garantee (will test it and certify it in writing). From what he said it's just like a basic BIX strip with 4 pair marking rated CAT5e. Anyone aware of this ? He said it's ok to splice the existing cable to a 200 pair Cat5e tie cable back to our patch rack. We are basically renting more office space that was prewired. The wall where the old patch panel will go and we also prefer having all active devices directly in our rack which is about 30 feet or so away. I'm not looking for ways of "splicing". I'm just asking if it's true. This is a big cabling company that subcontracts for the local telco. They are Nordx certified installers but not resellers. We are still in the quotation stage so no contracts have been signed yet. Also at over 100$ a drop in a fairly easy office space (all suspended ceilings), I find them a tee bit expensive. I understand the first run is more expensive but if you have 10 runs going down the same power pole, charging 10 * 100$ each is a little too much.

Yes, there are connecting devices that can be used for "splicing" CAT5e cables. One is the NORDX GIGABIX connector and the other one that I know of is like the Siemon 110 connector series they call, I think, the Siemon "S210" series connectors. They both can be used on CAT5e or 6 to meet your "splicing" needs when those situations arise.

I would look at both types to see which one might fit your application better for space requirements, etc.

Hope this helps!

Thanks. My cabling contractor is recommending Nordx. I usually use Nordx also.

for network cabling, i have heard some base their quotes on 2 1/2 hours per cable run, totaly terminated, jacked, labeled,and verification tested. this is a basic site unseen projection, with site survey to evaluate to project less time per run.

what do you guys use for a rough number, site unseen.

A second cabling contractor uses (I believe) 70% of the longest run calculate the average runs.

Well we have asked another quote to have the cables removed and brought directly into our H frame. We don't want any consolidation points. The runs that aren't long enough will have to be recabled. Luckly the are very few runs that aren't long enough because there was a large conference room close to the patch panel. Still waiting on the numbers but already I think the quote is over 10 000$. We also asked them to reroute all the phone cabling too. There's over 5 sets of 250 pair bix mounts to move. I doubt all those are used. There isn't physically that many jacks on the whole floor. Probably left overs from MAC or after renovations.

as for splicing---here is a product from AllanTel part number AT66CB-15

I think Amp/Tyco also has a similar box---my question is if these are made by these reputable companies--how does this fit into practice? Are they used for when you come up short on a cable or when one gets inadvertantly cut?

Problem solved. We are doing it the RIGHT way. We didn't want to have any future hidden problems. All the cables that are long enough will be reterminated in our rack. The ones that are too short will be rerun. All voice cables will be rerun because the telephone system was maxed out and not under our control. We will be putting in a BCM400 but all the phone lines are terminated in the old location. We will be bringing all the voice into our data rack also. We did a walk around the premise and we found all sorts of things in the ceiling. Half of the 40 or so office have 25-pair trunk lines that were termined at one point. There are about 200 voice drops for 40 offices that were independant of the 25-pair going to each office. We found a Dees CM30 call monitoring system installed on the main lines but no one knows who's monitoring it or if it was left over from previous installs. We also found a Comstar unit that seems to be unused. We also plan to running CAT6 for 2 offices because they are heavy bandwidth users. We want to see how well it performs between running old cat5 (not 5e) cable on simple Linksys Etherfast switches and Cat6 with HP Procurves capable of 1Gb.
