Test OSP Voice cable

[randall5]

I have an upcoming project where we are splicing and extending a 200 pair OSP cable. Part of the spec calls for "OSP voice cable shall be tested, end to end, using a gang tester to verify continuity, polarity, and wire-mapping." What the @#%$ is a gang tester? I have a meg-meter and a Fluke DSP. I suppose I could hook up a simple 4 pair tester and modify some cords to see if I have the pairs right. Any thoughts?

This is normally done as part of cutover. Will you be cutting over?

Throwmaster is the industry standard for testing during cutover. It allows pairs to be cutover one by one.

I have one that I would consider renting or selling.

The Testmaster 108 seems to be the tool:

Wires,

yup, that is the equivalent of the multipair throwmaster I have.

The main difference is that the older throwmaster box requires manual scan of each wire whereas it looks like the testmaster automates the scanning.

These things are really cool - you can cut over lines that are in use!

OK, guys.

I appreciate the input, and understand what they are looking for. Now for the follow up questions. Is there another way? We are talking about a brand new 200 pair cable on a school campus that will have nothing in service until we are finished. There is no cutover, no working lines to worry about. All we need to do is test pairs for continuity, and open/short, etc. I just don't think we have budgeted for a tester like that which I would use for 8 25-pair bundles and then let it sit in storage for 6 months.

Hi,

If you are willing to ignore the "gang tester" requirement it seems you have the equipment to handle the required tests. You have to go with your own conscience on that one.

Are there any splices? If there are, you need to be able to determine if there are split pairs since those are clearly important to the performance of the cable.

You will need to test continuity from every wire to every other wire to ensure no crosses are present.

I do see used Throwmasters on eBay from time to time which is the only reason I own one!

Worst case rent a gang tester, though obviously that would cut into your profit.

Best of luck

You could go the old school way and use a single point meter (kick meter) and a guy on the other end sending you shorts, and tip to grd, ring to grd tests. (tip/ring to grd can constitute testing continuity)
A sidekick meter will do this as well as show you if there is noise on the line (usually caused by faulty splices, cross', wet cable etc.)
