| Horizontal Cabling onto 110 Blocks. |
Sirs,
I am aware that horizontal runs can be terminated onto 110 blocks - this seems to be a more cost effective option with less space required.
However I am little unsure of the method of terminating 4-pairs onto a block and also patching 2pair jumper wire from the designated cable through to active equipment. Could you shed some light on this for me please?
For larger install's is this a better solution?
Where can I find more information on this?
Kind regards |

Dear Bob,
We have several pages describing 110-type block terminations here at Cabling-design.com:

You may want to check them out.
On the actual effectiveness of the solution: it does depend on what type of active networking/voice equipment you will be using. If all your connections are for Ethernet network, then you better of using RJ45 modular patch panel because you can use the same patch cords to do cross-connects in the closet and connect PCs to wall jacks.
On the other hand, if your cabling system will be used for both Ethernet and voice, it's more convenient to use 110-type blocks because you could patch 1-, 2-, 3- and 4 pairs with cross-connect wire instead of an RJ45 patch cord that can only patch 4 pairs at once.
Please note that 2-pair jumper (cross-) wire is never connected to equipment (except if you do it intentionally and crimp a plug at the other end of that wire). Those wires are used to connect between two cross-connect fields on 110 blocks.
Sincerely,
Dmitri Abaimov, RCDD
