Cabling Above Ground Possible?

[grundy]

Strange situtation here as always. There are two residential buildings zoned for business. Building A is approx 10ft from Building B. All that seperates them is a small driveway. The company in building A has expaned over to building B until they move to a bigger building. They need to bring phone exts from A to B. Is it possible to run cable above ground say at attic level or second floor level.

I was thinking a steel line between the two buildings. Some outdoor Cat5 in a waterproof conduit across the line?

What do you guys recommened? What would work? Is there an easier way?

Either supplier can get you the shiled connectors,bonding clamps, ground wire, etc.

Also the 3 element gas tube lightning protection modules. They make protection block with the modules for 25 pair that are the size of a 66 Block (Marconi or Porta, for example.
For your CAT5- If you are running more than 2 to six of them - just buy 2 more 25 pair protection blocks for them

Sphoneman,

Thanks I'm going to order some of the Porta Systems stuff. Seems pretty good.

The only other problem I'm going to have is where the strandvice is on one building, I will need to run the Cat3 and Cat5 down the outside to the basement where the network equipment is outside. Is it possible to cut the messenger away from the Cat3 so I can run it down? Or Is it going to be too hard becuase its bonded.

So Cat3/messenger connects up towards 2nd floor, and then from there just run the Cat3 down to the basement? This is only needed for 1 building. The other building has the network equipment in the attic

Is it possible to seperate the messenger from a figure 8 cable for like 25 feet? So the messenger can dead end into the wall and the cable can continue a run?

Yup, just use your splicer's knife, or a utility knife with a lineolum (hook) blade works great. Just be careful not to cut into the cable!

Or be a man and pull on the messenger... duh...

Well everything is going well, but I am at the point of stripping the 25 pair to make the connections.

1. I'm having a heck of the time finding a cable stripper.

2. In addition, once I strip it, the pairs arent in bundles, how am I supposed to know which to terminate where, there are like 5 white etc. I could tone each one??

Thanks for all the help.

If you do a good job of stripping the cable you should have twisted (not always very tight) pairs. w/bl, w/o, w/g, w/br, w/s. Look closely you will find the twist.

 

[grundy]

I dont have any twists. The cable is wrapped with 3 pieces of stirng around the outside. I don't have any twists. I tried to tone the wire across but the tone is not reacing the other side. It's being spread out through all the cables.

Did I use the wrong cable?

Give yourself a couple of extra feet of slack when stripping the cable. Carefully look at the lay of the pairs. Pick out each pair and put a knot in the end to keep it from seperating. Be glad it's not filled with icky-pic.

Yes, I'd strip back about 3-5 feet... and if you take them apart, there will be a twist every couple of feet.

With any aerial or underground rated service cable, there will be no tracer to the tip of the pair, it will only be the binder color.

When we splice large pair count cables (ie. 25+, even up to major counts, ie. 1000+) we use the same method, albeit using the "strings" you mention which are binder identifiers to differentiate. It is a slow process, but once you get used to identifying the twists -- you'll get it down. It's not like a UTP cable, we're talking a very slight twist over several feet.

If this cable is PIC (gel) filled, you'll want to use an orange based solvent to remove the gel filling. My personal favorite is goo-b-gone, there are commercially available cable PIC filling desolvers, although goo-b-gone is readily available, and considerably cheaper. If you stock an orange based wipe in your vehicle, ie. Klein or Dottie's handy wipes for your hands, these are also orange based and work very well for nuetralizing the pic filling prior to splicing.

That's my two cents on the matter...
