Basics and Benefits of Zone Cabling – Part 3

20 Dec 2017

Structured Cabling,Network Cabling ,Data Cabling Washington D.C As discussed in Part 2, there are considerable cost savings from the deployment of zone cabling systems. Part 3 will continue discussing the basics and benefits of zone cabling.

Additional Zone Cabling Benefits

Additional IP devices for audio & video, BAS, digital signage, voice, data security, digital signage, WAPs (wireless application protocols), etc. can be integrated easily into the current structured cabling system through ZE (zone enclosure) connections.

Extra ports within the ZE facilitate fast MACs (moves, adds, and changes) of current service configurations.

For easing installation and decreasing labor costs, tested trunking and factory pre-terminated cables can be utilized.

Increased efficiency of pathway utilization will be realized for the entire facility space.

Structured cabling system deployment will be speedier and cause less disruption.

Smart & Green Building Designs

Perfect for smart and green building designs, zone cabling systems can reduce labor expenses and waste of cabling materials. Centralized connections inside ZEs achieve greater efficiency for the routing of pathways. LEED credits provided by the United States Green Building Council (USGBC) can be maximized. In addition, cable sharing can support several low-speed and low pair count applications functioning on a single 4-pair cabling system. This achieves greater efficiency in cable and pathway utilization.

Summary

Modern workspaces are becoming more social and flexible, and they are increasingly reconfigured and updated with greater frequency.

Zone cabling systems allows flexibility in work spaces, facilitating faster and less disruptive moves, adds, and changes than traditional cabling systems.

Zone cabling allows for greater efficiency in the use of pathways and materials, which is required for smart and green building designs.

CAT 6A shielded cabling is recommended in zone cabling designs to achieve maximum performance.

Shielded CAT 6A zone cabling designs result in greater performance, better support of remote powering applications, and ZE termination flexibility at practically no additional cost in comparison to CAT 6A UTP designs.

Regardless of size, zone cabling installations planned with 25% spare port availability will considerably decrease client disruption and allow the facility owner to recover the expense for extra ports inside two to five years or after achieving the threshold for ROI.

About Ethernet Cables and Data Shielding

Network cabling, cables,shielding The Ethernet network cable connects devices on a LAN (local area network) such as personal computers, switches and routers. These cables are typically Cat5 and Cat6. These cables provide the infrastructure that connects the PCs, printers, router/modem and other peripherals to a switch. The cables are made up of stranded or solid copper wires. Stranded wires are not as susceptible to fractures but are more difficult to terminate. Solid Cat5/Cat6 also is less susceptible to electrical interference. These shielded cables are made up of braided strands of copper wrapped in a polymer layer and spiral copper tape. The shield is applied across the splices.

An Ethernet cable can be compared to an electrical power cord in that it can only extend a limited distances because of the electrical transmission properties. Meanwhile, wireless technologies (Bluetooth and Wi-Fi or local wireless technology) have enhanced the reach of Ethernet in residential and enterprise networks. The standard Ethernet cable consists of four coiled pairs that terminate at the eight pins of the clipped connector or "RJ45" at both ends of a cable. At the wallplate is simply the female end of the same connector. The cable is made up of unshielded (UTP) or shielded twisted-pair (STP) cabling.

Shielding is not selected automatically during installations. The answer is, it affords the protection required for certain environments although there are also some downsides. One is mass. The single-shielded cable made of Ethernet weighs approximately 12 percent more than the unshielded cable. The double-shielded version is roughly 30 percent heavier. You may be putting together dozens or perhaps hundreds of individual shielded twisted-pair cables along a ladders tray above the ceiling, under a floor, or at the back of panels. The aggregate weight of these cables can collapse the mounting bracket.

Cable flexibility is also an important issue. Take care when you pull the cables through conduits. The cable shielding can make installation more difficult. The sole foil shield can crack while the sharp boundaries of the shield can scrape the insulation of individual wires. This can cut the wire and cause data transmission issues.

What are the shielding options?

You have a number of shielding choices in for your Ethernet network. The single-shielded cable has the lightest protection. Double-shielded cables contain a foil and plate shield. It can ensure better protection against electromagnetic or radio frequency interference and reduce issues related to cable relocation. High-flex industrial cables are fabricated and protected for uninterrupted applications. These have special jacket materials to address industrial and outdoor concerns.

Shielded or Unshielded Cat6 cable?

cat6-cabling,data cabling, With high bandwidth applications and network systems venturing into factory environments, the need for shielded Cat 6 cable has increased. In these new areas of installation, the environment where the network cable is run has large amounts of EMI (Electro-Magnetic Interference). Although Cat 6 cables have improved cable twist to reject noise and handle gigabit Ethernet this by itself is not enough for high EMI environments. A shielded Cat 6 cable helps in high EMI installations. These high performance cables ensure the data within the cable will be protected from EMI, resulting in higher speeds and better data transmission.

Grounding Necessities for Shielded Cat 6 cables

Shielding helps protect the data from electromagnetic interference from outside sources that could alter or weaken the signal traveling through the copper in the cable. The shields of the two connectors are electrically tied together by the drain wire. However, they will only become grounded if the jack they are placed in has its shielding tied to ground. If you are setting up a network with Category 6 shielded cables, you should use Cat 6 shielded couplers and jacks.

Installation caveats

Category 6 and 6a cable must be properly installed and terminated to meet specifications. The cable must not be kinked or bent too tightly (the bend radius should be at least four times the outer diameter of the cable). The wire pairs must not be untwisted and the outer jacket must not be stripped back more than 1/2 inch (1.27 cm).

All shielded cables must be grounded for safety and effectiveness and a continuous shield connection maintained from end to end. Ground loops develop when there is more than one ground connection and the difference in common mode voltage potential at these ground connections introduces noise into the cabling.
