Copper Cable For Data Applications

As long as you follow the ANSI/TIA-568-C standard,most of your communications infrastructure will be pretty similar and will not vary based on whetheris supporting voice or a specific data application . The horizontal cables will all follow the same the structure and rules .However, when you start using the cabing for data applications, you 'll notice more differences .We will now take a look at a couple of possible scenarios for using a structured cabling system.
The typical horizontal cabling terminated to a patch panel .The horizontal cable terminates to the 110-block on the back of the patch panel .When a workstaioni is connected to the network,it is connected to the network hub by means of an RJ-45 cable that connects the appropriate port on the patch pannel to a prot on the hub.

The use of a generic Pre-terminated patch Panel  allows this cabling system to the most versatile and expandable .Further ,the system can also for voice applications if the voice system is alos terminated to patch panels.


Another scenario involves the use of 110 -blocks with 50-pin telco oconnectors.These 50-pin telco connectors are used to connect to phone systems or to hubs that are equipped with the appropriate 50 pin telco ingerface.These less versatile than patch panels because each connection must be terminated directly to a connection that connects to a hub.
A final scenario that is a combination of the patch panel approach and the 110-block approach is the use of a 100 block and 110 block patch cables.This almost identical to the patch panel approach ,except that the patch cables used in the telecommunications close have a 110 block connector on one sied and an RJ-45 on the other .

You will also find 110 blocks onthe back of patch panels; Each 110 connectin block has a corresponding port on the patch panel .The front side of the patch panel shown in figure 1.0 shows a 96 port patch panel  ,each port will have a corresponding 110 connectin block.

A standard universal telephone closure can also be used to house splice fiber -optic cable.An organizer panel holds the splices.Most organizers contain provisions for securing would be the behind the wall cables in a building network.These would run to the rear of the patch panel .Patch cable would then run between the patch panel and the equipment,By rearranging the patch cables,you can connect ports on the equipment to different cables in the buiding .Another use for a patch panel is to form a transitioni point between multifiber cables and duplex cables.A 72 port fiber patch panel can connect to 72 separate adapters in the patch panel .Individual or duplex cables then connect to the front of the patch panel .
