How to Integrate Shielded LAN Cables into Existing Network Infrastructure
Shielded LAN cables offer several advantages over unshielded cables, including improved signal integrity, reduced electromagnetic interference (EMI), and increased security. However, integrating shielded LAN cables into an existing network infrastructure can be a complex and challenging task. This article will provide a step-by-step guide on how to integrate shielded LAN cables into an existing network infrastructure.
Planning and Design
The first step in integrating shielded LAN cables into an existing network infrastructure is to plan and design the new cabling system. This includes determining the type of shielded LAN cable to be used, the routing of the cables, and the location of the grounding points.
Type of Shielded LAN Cable
There are two main types of shielded LAN cables:
Foiled twisted pair (FTP) cables have a thin foil shield that surrounds each twisted pair of conductors.
Shielded twisted pair (STP) cables have a metal braid or foil shield that surrounds the entire cable.
STP cables provide better EMI protection than FTP cables, but they are also more expensive and difficult to install.
Routing of the Cables
The routing of the shielded LAN cables should be planned to avoid sources of EMI, such as power lines and transformers. The cables should also be routed in a way that minimizes the number of bends and crossovers.
Grounding Points
The shield of the shielded LAN cables must be properly grounded to provide EMI protection. The grounding points should be located at the following locations:
At the patch panel or wall plate
At the network switch or router
At the grounding busbar
Installation
Once the planning and design phase is complete, the shielded LAN cables can be installed. The installation process is similar to the installation of unshielded LAN cables, but there are a few additional steps that must be taken:
Prepare the Cables
Before installing the shielded LAN cables, the ends of the cables must be prepared. This involves stripping the outer jacket and shield back about 1 inch, and then folding the shield back over the cable.
Install the Cables
The shielded LAN cables can now be installed in the same way as unshielded LAN cables. The cables should be routed through the cable trays or conduits, and then terminated at the patch panel or wall plate.
Ground the Cables
The shield of the shielded LAN cables must be properly grounded. This can be done by using a grounding strap or by connecting the shield to the grounding busbar.
Testing
After the shielded LAN cables have been installed, they should be tested to verify that they are working properly. The following tests should be performed:
Continuity test to verify that the cables are properly connected
EMI test to verify that the cables are providing adequate EMI protection
Speed test to verify that the cables are capable of supporting the required data rates
Conclusion
Integrating shielded LAN cables into an existing network infrastructure can be a complex and challenging task, but it is essential for ensuring the proper operation of the network. By following the steps outlined in this article, you can successfully integrate shielded LAN cables into your network infrastructure and improve the performance and security of your network.
