Cabling Issues

11 Apr 2013

data cabling,,DC One of the most important things about cabling is to purchase cable not just for what you’re using now but for what you may run in the future. A rule of thumb is to install the highest-grade cable that your budget allows.

The standard is Ethernet. That means there are two basic types of cables to use: copper Ethernet and fiber optic Ethernet. Copper Ethernet cabling is generally used to connect the data center equipment to the end-user, while fiber optic cabling is used to network the infrastructure and to

"Structured cabling” is a complete system of cabling and associated hardware which creates a telecommunications infrastructure. This infrastructure can serve a range of tasks, such as providing telephone service or data transmission through a computer network.

Every cabling system is unique. Variations in the structure of the facilities housing the installation, the specific cabling and connections needs, use and function, as well as customer needs requires standardization to ensure acceptable system performance from increasingly complex systems. The American National Standards Institute (ANSI) is the responsible organization

Cat 6 While WI-Fi and other wireless network technologies have improved greatly over the years, nothing beats the reliability and performance of a wired network in your home or business. One challenge that people face is what kind of cable they need for their needs.

Although there are dozens of network cable types, the fact is only 3 types of network cable is commonly used in home and small business networks: Category 3 (Cat3), Category 5 (Cat5), and Category 6 (Cat6).

What is “Structured Cabling”?

14 Mar 2013

Stu Kushner

Structured cabling is a telecommunications cabling infrastructure consisting of a number of standardized smaller elements called subsystems.

Structured cabling falls into five subsystems:

A Demarcation point is the connection point where the telephone company network ends and the customer’s on-premise wiring connection begins.

Equipment or Telecommunications Rooms contain equipment and wiring points that serve the users inside a building.

Vertical or Riser Cabling connects between the equipment/telecommunications rooms on different floors.

Ethernet Wiring for Home Networking

Network cabling,Office Cabling in DC Although “Wifi" is simpler for a lot of people, due to multimedia sharing, bandwidth on some home networks, some users really want a hard-wired home networking solution. A wired network allows a private, high speed, network at home for Internet access, file sharing, media streaming, online gaming (console or PC), IP security cameras, or other standard Ethernet type wiring use.

There are certain design considerations that need to be addressed based on needs. Answering these questions will affect quantities, tools and materials needed.

The basic questions are:

Which room(s) do I want wired?

How many ports do I want in each location?

What is a good location for distribution?

If the internet comes over a cable into the house move the cable modem there so it will be able to supply internet access to the entire network. Another consideration is the amount of space needed to hold the network equipment.

What path should the cables take?

This is the most difficult consideration. For single floor homes the basement may be the best path. For multi-story homes you have to be creative. Outside may be an option or use an old laundry chute. The other consideration is cable length. The max cable length for up to gigabit speeds over copper UTP cabling is 100 meters (300 feet). This should be plenty for most home applications.

What network speed do I need?

This will determine what kind of switch to get. 10mbps is faster than most home internet connection. If you just “surf” the internet, use a 10 megabit switch. If you are planning on sharing multimedia over the network 100 megabit switches are available and reasonably priced. If you must have the fastest, go with a Cat6 Gigabit cable.

Cat6 Q&A

4 Feb 2013

Stu Kushner

What is Cat6? Cat6 components are interoperable between different vendors and are fully backward compatible. Cat6 has the same nominal Impedance of 100 Ohms as Cat5 and 5e components, but with tighter tolerance on Impedance variations. Transmission parameters are specified to 250 MHz, compared to 100 MHz for Cat 5/5e.

Do Cat6 components behave differently? The diameters of Cat6 cables range between 0.21 to 0.25 inch (5.3 - 5.8 mm) compared to Cat5/5e’s range of 0.19 to 0.22 inch (4.8 – 5.5 mm). Cat6 also has a tighter twist length to reduce crosstalk interference.

What about installation? Cat6 cables and components are installed similar to Cat5/5e. There are design and installation issues that contractors and installers must pay greater attention to; including cable terminations and the pathway fill.

Will Cat6 supersede Cat5/5e? Yes. The only question is when. The installed cost for Cat6 cabling can be about 20 % higher than Cat5e, but prices will decrease as usage increases.

Will Cat6 deliver what is promised? Yes. There are no technical obstacles. Test parameters and procedures to qualify Cat6 components to ensure interoperability between different vendor’s products are in place and detailed.

What about the installed performance compared with Cat5/5e? The biggest benefit is much-improved Signal-to-Noise Ratio at the Receiver: Cat6 provides about 16 times better Signal-to-Noise Ratio compared to Cat5/5e over a wide frequency range.

Why do we need Cat6? The real question is “is Cat5e good enough for today and in the foreseeable future?” The answer is “Yes, but…”. Network switch ports are often at the “marginally compliant” limits of the IEEE standard and susceptible to cabling and temperature variations. Cat6 provides fewer bit errors than Category 5e for 100BASE-TX and 1000BASE-T applications.

The Good, the Bad, and the Ugly: Cabling Lessons Learned

A magnetic field when running low voltages. Unfortunately, when this unshielded cabling creates a magnetic field created. Any electrical cabling bear by disrupts communication, slowing transmission or preventing Network cabling is a tricky. Even with a solid background, technicians without adequate knowledge and training can make mistakes that may shut down an entire system. Here are some typical mistakes seen in network cabling.

Plan for the Future. Cat5 may be the cheaper option, but can cause problems when upgrading is needed. Install Cat5e or Cat6 cables with options for upgrades to save labor costs.

Don’t Mix and Match. Twisted pair cabling was often out of the price range for many companies, so priority was given to data, while voice had with cheaper cabling. Now, VoIP has made voice equal to data in importance and need. Fortunately, a typical VoIP phone has a built-in Ethernet connection or pass-thru that is compatible with almost any data cable, which decreases installation costs.

Don't put Electrical Cables Next to Data Cables. Data cables use twisted pairs of wires inside that help produce transmissions altogether. This generally happens when the cables are running parallel, so if your cable is near a power line, lay them perpendicular to the power line.

Not Laying New Cable When You Need To. Ethernet switches are convenient, but can be misused. Mini-switches are often added to provide a few extra ports; but this can cause bottlenecks and instability. Add extra cable instead, if more network resources are needed.

Forgetting Cable Management. “Ladder racks” add extra cost to an installation, but they also make the installation look better, run better, and easier to maintain and update. Also, don't forget to color code or label your cables, so technicians can actually find the right cable later.

Do Not Use Basket Tray against a Tight Ceiling

8 Aug 2012

Stu Kushner

When a new office design is in its initial stages, it is critical to consider proper handling of utilities, power water and cabling inside the walls and ceiling. For cabling, it is necessary to use hooks to hold the cables above the drop ceiling. When the installation of cable involves large numbers of cables traversing lengthy expanses, it is normal to install cable ladder trays up in the ceiling to carry the bulk of the cable along the main corridors of the office. Cable ladders vary in quality and cable handling capabilities. The amount of cable and the budget of the project will determine the type of cable ladder that will be built.

A higher quality cable ladder will, in the long run, save time and money during the installation phase of a cabling project. The alternative to a cable tray is to install cable conduit. Considerations in choosing to use a cable ladder tray system include the following:

Network Cabling, Data Cabling, Cat5e Cat6/6a Cabling,VOIP Phone Many small business owners are fearful of making major changes to their office operations due to the fact that the disruption could cause headaches and service issues. When it comes to upgrading to VOIP service from traditional phone service the switch is likely much simpler and stress free than most small business owners would believe.

The old adage, “if it ain’t broke don’t fix it,” may make perfect sense in many situations relating to small business operations but making the switch to VOIP phone service certainly isn’t one of them. Upgrading to voice over internet protocol can be performed quickly and seamlessly and the potential benefits of VOIP make the switch completely worthwhile for any size business.

Upgrading to VOIP phone service in your office eliminates virtually all of the complex equipment that you are required to keep on site for proper operation of your traditional land line service. As this equipment is removed from your office the excessive leasing and maintenance costs are removed as well which results in a substantially smaller monthly phone bill.

VOIP phone service can be implemented into your office environment in as little as fifteen minutes once you’ve got the phones. This means that you won’t lose any precious time communicating with your customers during the transition. Upgrading your current phone system is a virtually hassle free way to enhance your ability to stay in contact with customers and coworkers and to dramatically lower your cost of office operations.
