Thanks ev.

It might not be a bad idea to go back to the equipment end and see what kind of termination job and protection is there. Heaven forbid you go to the trouble of doing this just to have some act-of-God knock them out and you get the blame. Heck, we've been blamed for HVAC systems going out a day or two after we did a simple install.

You are not kidding. Just our truck in the parking lot and everything that stops working from that day forward had something to do with us. It kills me when we are working in a high-rise and a completely different office starts having problems with their paging or something like that. "It must have something to do with what your people were doing ten floors above".

How come there's always enough time to go back and fix it a second time?

I would probably go with one pedestal, and make the other side a splice in a cristy box.
That gives you a test point, and access to both ends of the cable section.
Either that, or just two splices in cristy boxes.

I'm new to the forum, but not new to telephone work. Everyone has given you the possible options, which all are a possibility. For what it's worth, if it were me, I avoid buried splices if at all possible. Doesn't matter to me if it's air core of filled cable.

No protection? Needs protection, period. (there are particular exceptions about bonding and grounding the cable shield when located within the ground potential rise, GPR, area of power generating or sub station, but that is another entirely differenct subject)

One comment, about the non shielded cable. That's a bad deal, not only for lightning purposes, but one big reason is power influence. I've been doing alot of noise and power mitigation and when we have an open cable shield where we have exposure to power, aerial or buried facilities, there is nothing to throw it 180 degrees out of phase from our cable pairs. For those of you that perform noise mitigation, you know what I mean.

Thanks for letting me jump in, and from what I have read so far on this forum, you all have alot of knowledge.

I agree with your analysis of power induction on non bonded cable. If it were me, in that envionment, with what he has to work with, I'd just replace the cable between the two buildings, no peds, no splice and a sheathed cable and protectors for all the reasons stated.

justbill,

If it was me, and that was possible, that's exactly what I'd do too.

Sounds like you know about running power influence problems, so having said that, if he can't make MGN connections it won't even matter....

Gotta throw in my $0.02.

I think I would try and go with 2 vaults. I don't think I would EVER consider burying a splice! I have seen too many pedastals run over detroying the contents. I would definitely convince them to at least start doing things correctly. dig down at least 3' install at least 2' conduit (small run across the road shouldn't be an issue) and install vaults. all futer adds and repairs will be a breeze and no worry of vehicular damage!
as far as protection goes, you should, but economically I doubt it could be done. (Ground rod in the vault and bond your 50 feet of cable section to it? )
BTW, Vault is equal to a plastic irrigation box.
Good luck, better hurry before the weather changes.

Just a lowly I&R Tech here guys so I'll apologize in advance if this sounds stupid but I didn't catch any distances here and if the run from the "new" ped location to the shop is close enough wouldn't a couple of bsw's work? doesn't sound like we're talking about alot of copper being used here.

Ha just read the dates on the previous posts...
probobly done by now eh? duh.

There are many avenues for you to take........I would consider burying the spice. However, with technolgy changing and the customers demand growing as well. The existing cable may not carry the new circuits, so it may need to be replaced someday. I would purchase the best buried clousure and place a conduit under the drivway for future. Go ahead and bury the splice just be Damn sure your do a good job closing up the splice.......Good luck!!!
