What is 25 Pair cable?

Opinions everyone has one, and that is good. One opinion about installing computer cable in your home or office comes from already been there and did that.

When you’re going to cable an office building with lots of phones and data needs then you might be thinking about 25 pair cable. What is it? This is cable that is mostly run from floor to floor or equipment closet to closet. It has 25 individual pairs which are color coded. Termination can be on a 110 punch down block. Cat5e 25 pair cable is the one to think about when you’re cabling voice or data because Cat3 is only voice although older buildings use it for data, besides the pricing is about the same. So you’re better off with the higher rated cable. Riser rated is for indoor use.  In homes you really don’t need it, use cables like bundled multi cable like Cat5e combined with RG6/U for your video. Also, find out if you need plenum rated cable in your area.

Now if you’re running cable outside then there is 25 Pair Outdoor Burial cable. This cable is usually Gel filled. That will give you the most protection from the elements. This is used when you need lots of connections and running building to building and going to put it underground. Be sure to know the codes.  

When using this type of multi connection cable you will more then likely need to punch it down. The cable run into the equipment closet has to go somewhere. Punching it down onto a 110 Block is a good way to do. They are very versatile and allow for simple cross connection. You will though, need the right tools. One of which is a 110 cut and punch tool and another is a multi pair 4-5 pair slap punch down tool. The latter allows you to punch down the combs that go over the initial 110 block. First is the block with the cable run to the color coded combs then the combs that are punched over the top of the initial ones for cross connection. Get the right tools to make the job successful.
