your leaving the bldg and now subjecting the network to potential lightning strikes

Ive seen the protectors Ed recommended literally blown across the room . glass doesn't conduct

can they afford to lose them after a thunderstorm ?

whats the data / hardware /downtime worth ?

keep in mind the power can travel both directions and Ive seen lightning do strange things the two computers could be fine and the rest of the network out




fiber isn't all that much more I bet I could do it very close what what the coppers going bill out at

most of the stuff pictured in the "ugly work " thread is working just fine .
it works just fine until ...

I have a situation similar to Arthur's: Customer has two steel buildings about 15'-20' apart. They're only now planning computer connectivity to the "lower" building and I've talked them into fiber and media converters. Oh, I've also talked them into some protection for the phone lines between the buildings (currently no protection, or more properly, no current protection, and they are just about at the highest point in the state, on top of a hill, in the middle of a field. I don't see any potential problems here!).

To answer Arthur's initial question, even if you used the 66-Blocks as you originally proposed, I would think that the circuit would work well, although it may not certify.

I've seen slips of paper in a case of cat 5e compliant Siemens 66 blocks saying not to use bridging clips for data.

I would love to know how they test out if you don't mind posting again after you are complete.

Arthur, what "flavor" of ethernet are they using? It makes all the difference... Here are the "rules of thumb" that I use:

10baseT You don't even need CAT5 blocks, plain 66 are fine, use clips all you want

100baseT Use the CAT5 66 blocks, one bridging clip is OK

1000baseT CAT5 66 blocks may work on short runs with NO clips and careful punching, but won't certify, not a good idea

10GIGbaseT Not even maybe. This can stop working when somebody merely touches a piece of active CAT6 cable.

If your going this route why even use a 66 block ?
your not going to need to pull the clips to troubleshoot nor will you be punching other cables down

DB to cat5e IW Scotch locked since money is the controlling factor a few scotchlocks will do the job as well or better than the 66 block for a fraction of the cost

since its in conduit why bother with DB ?

Skip, do we know each other?

I don't talk to my best friends the way you talk to me.

If you want a fight, go somewhere else. Your sarcasm is getting in the way of the topic.

My question involved HOW MANY SPLICES.

Not HOW TO DO IT.

It's in metallic tubing because I'm prudent and responsible. It's DB because that's what was specified by the customer, and I think it's a good idea.

I used to have a similar setup to yours (mine was aerial, boy did lightning like that!) Rather than use a 66 or Bix, I brought the PVC into one side of the protector and the OSP into the other side. Could you do something lie this?

A previous installer had a jack on the OSP then the protector then to the switch (both ends.) It worked also - same number of connections/splices as you. I had to replace that setup when I changed protection types after a particularly close strike took out both protectors and switches.

"computer - PVC 4-pair - 66 block - protector - buried type wire - protector - 66 block - PVC 4-pair - switch"

Use one of these cables as a feed to a switch in the remote building otherwise thats gonna be a pain in the rear when they need another run for an additional workstation. Yikes!

If you're just using it as a splice point I don't see a need for bridging clips. Unless you're running some real high speed stuff I think you'll be fine with the set up you discribed. I don't know as there is a "number of splices". Most tell you not to splice it at all. Bottom line if they can run data without problems that's all that matters.

Allentel makes a product like this but I can't find it on their site. I would use this for data instead of 66 blocks if you need to splice in-line.

It looks similar to this:
