network cabling,Data Cabling It can lead to a lot of negative outcomes such as paralyzed network performance, maintenance troubles and hidden costs. Network cabling can be especially troublesome if it is installed by individuals without the proper knowledge and tools. When it comes to twisted pair cabling, there are many factors that you need to consider.

In the past, many companies installed different cable systems since twisted pair cabling was expensive. At present, full installation is still costly although a greater part of the expense is labor since raw cables is not pricey. Cable management is another concern.

It protects the cable from damage and does not contribute to optical wave guide properties. The coated fiber is a durable synthetic resin serving as a support for the cable’s core. Protective jacket layers are added depending on the cabling application.

Fiber over Copper

Fiber has benefits over copper. Fiber optic transmission does not emit Radio Frequency Interference or RFI. This guarantees secured communications since light waves can't be easily intercepted. On the contrary, copper wires give off signals that interfere with other electronic equipment. That is why utility firms now run power lines with fibers

Unfortunately, multiple issues can affect the data hub and incorrect cabling can be one of them. Planning is the key to boosting the efficiency of data center cabling.

Here are some things to consider:

Measure cables with care. Otherwise, you produce a twisted “rat's nest” and an unnecessary waste of money.

Put a label on both tips of your cables which include patch and short runs. This will be useful if you need to test a cluster of circuits. It will not be confusing if you unplug several patch cables. You know where each single cable is connected. The marking system must be consistent at all times.

Never rush on termination of cables. And redo in cases where cables lose connectivity. Avoid purchasing and using cheap products. You will end up spending more in the long-term.

Test the cables first and make sure it passes the mark for continuity. If not, you have to do it all over again. And always use a high-quality tester to avoid unwarranted work.

Patch cables must be kept short. Remember that rack servers are only one foot away from each other. Patch cables with a length of three feet are definitely not appropriate. Combine testing and terminating capabilities to make sure that patch cables connect accurately. Additional lengths will cause a lot of twisting.

Come up with a color coding technique. A single color is ideal for patch cables and cable runs. However, it is possible to utilize specific color cables for specific purposes. Avoid random colors. It will be easier to follow cable functions and resolve problems if your color has a purpose. Blue for data, white for voice is a common standard.

Your design must be cable-friendly. Do not put a rack in a place where it is not possible to run your cable effectively. You may end up with cables dropping from the ceiling or scattered on the floor. Expansion should also be in your planning so you know when and how to make adjustments.

Separate electric wires from Cat5/6 cables. Power lines can distort communications. The effects will be to have connection and data transmission issues that can result in data corruptions.

Be careful about excessive temperature. Make sure that the cables are cool and not hot since this can result in cabling decomposition. The data center should be designed in a way that servers and networks are always at a comfortable temperature.

Network Infrastructure Planning

28 Jan 2015

Stu Kushner

What is a network?

The network is classified as a group of hardware and software components that connect devices within a company and link that entity to other companies in the world-wide web. The hardware for networking consists of network interface cards, computers, routers, switches, patch panels and cables. Software refers to network services and protocols that facilitate communications. The hardware components should be installed and configured before the software and operating systems are initiated. Network communications serve as the core foundation of the whole system. It makes up the services that build the network’s framework. The key is to determine the infrastructure based on the objectives that you have set so the architecture can scale up as a companies needs grow.

The Operating Systems

Begin by understanding the current setup. This will allow you to establish how to plan for your operational targets and objectives. Draw a full map of the current network. Include these all cabled connections, server information, location of devices in the network, and all of the users. Complete this inventory first. Then, proceed with reviewing all available information in combination with the future goals. This will enable you to fully understand the required changes needed for deployment.

The operating systems or OS installed on computers make up the primary software components in a cabling infrastructure. The OS contains protocols that facilitate network communications. It also consists of applications and services that secure the data. Conventional features include connectivity, security, control of access, and routing/switching functions. There should an existing network before installing servers to support applications. These consist of file, print, web, messaging, application, and database servers.

Meticulous Planning

Document the physical hardware and software components

Decide on the actual location of each components.

Determine configuration requirements.

Buy, assemble and mount the hardware.

Install and configure your OS, apps as well as other software.

Be sure to understand the network’s physical design. If there are multiple heavy or data intensive workloads, servers will need more bandwidth and connections to deal with the data traffic. Network resources need to allocated among the numerous applications which mean that vital applications can affect performance considerably. Planning becomes an integral component of development and should be specific to the business plans.

Keep track of existing workloads and use performance results as a reference. There should be proper tests to determine the performance of your network. Speculation is not advisable because that can cause mistakes and overspending.

Important Facts About Cabling Infrastructure

23 Jan 2015

Stu Kushner

Network cabling that has not been installed properly may result in various communications issues. Even minor problems such as a connector that has not been terminated properly can prevent Power over Ethernet from performing well.

Wiring Standards

See to it that you use appropriate wiring patterns which are T568a and T568b. Refrain from bringing together T568a and T568b in the same cable. And always use premium quality Cat6 or Cat5e cables. We prefer solid over stranded wire.

Essential Issues in Design of Structured Cabling Systems

Structured-Cabling,Data Cabling Structured cabling systems (SCS) refers to the local area network cabling system designed exclusively to fit a company's requirements. It combines data, voice, video, and management systems sometimes including alarm and security. SCS insures that all of this information is transmitted promptly and efficiently. The structured cabling system normally includes transmission products with engineering design rules that create a stable transmission system.

Network Foundation

The structured cabling system is said to be the groundwork of a successful building and office setup. It is also the fundamental foundation on which all other equipment relies on.

Unique Properties of Fiber Optic Cabling

30 Dec 2014

Stu Kushner

Network Cabling ,Data Cabling, Fiber-optic cable Fiber optics is capable of resolving many issues in data communications. However, computer data is normally transmitted over ordinary copper cables because it's adequate at lower speeds and shorter distances. It is not advisable to utilize fiber cable in these ordinary instances because of the high costs.

Fiber is impervious to electromagnetic interference because the signals are transmitted as light impulses. That means that Electromagnetic Interference (EMI) is not possible. Light waves are not effected by magnetism. This type of impediment can happen in coaxial and Cat5/6 cables because electricity can interfere with data signals over copper wires. Magnetic fields produce electrical current and this electromagnetic Interference is noise that can scramble data.

Fiber optic cabling also is much better at providing security of data since electromagnetic fields are not emitted around optical fibers. The data is restricted within the structure of the cable making it impossible to tap signals being communicated without cutting across the fiber. Emissions can not be easily intercepted. Hence, the fiber is by far most secure channel for carrying sensitive data.

Fiber is also a “non-conductive cable” because there is no metal in its design. It's a highly purified glass fiber. While copper is a conductive cable that can attract power surges and unwanted current. With fiber, outdoor varieties are costly because these call for special strength. Therefore, fiber optic cable is usually more cost-effective for indoor use. With copper, it is also important to get rid of the current commonly known as ground loop. The metal cable can run into signal transmission distortions due to slight transmissions in electricity.

Fiber optics also does away with threats coming from sparks. The transmission of signals can be hazardous because of this phenomenon. Although the spark itself is not dangerous, it can lead to greater problems especially in industrial and chemical plants where the air is polluted by possibly dangerous vapors. Fiber cable does not generate sparks because it carries no electrical current.

Installation of fiber is less difficult because of its small size and flexibility. And fiber optic cables can pass along the same route as electric cable without producing any noise. The size, lightness and elasticity of fiber optic cables also makes them suitable for short-term or portable installations. And they transmit signals over longer distances too. Amplifying the transmission capability of copper wire cables makes them more unyielding. Thicker copper cables are also hard to mount in spaces where the cables have to pass through cable conduits and concrete walls.

Fiber optic means higher bandwidth too. It has the capability to transmit high-speed signals over lengthy distances without repeaters, unlike copper cables. The fiber optic’s range is not infinite but it is way more than copper cable.

Issues to Avoid with Cat6a Cables

22 Dec 2014

Stu Kushner

A newly popularized cable is Cat6a. It is the new “cable on the block” which has prolonged the life of copper cabling. Cat6a has the shielded twisted and untwisted pairs with different advantages and features. It supports Gigabit Ethernet up to a hundred meters. However, you need to understand and cope with several issues.

Contentions

The size of Cat6a cable is larger than Cat5e. Copper is inherently unreliable due to Bit Error Rates or BER. This is why manufacturers have designed Cat6a cables with a smaller cross-section. It takes up less space in the tray. Yet, this space is needed to minimize crosstalk between cabling pairs. The protective shield in Cat6a cable adds to the expense.

Electricity and Mechanical Facets

Aside from the electrical issues, Cat6a Untwisted Pair (UTP) is fabricated with bigger conductors. It has more rigid twists compared to Cat5e and Cat6 and these heavier conductors plus large and stiffer jacket combines to make for more difficult cable installation. Besides, the external diameter of the UTP means that the Cat6a cable takes up more room in the trays and conduits.

Electrical and mechanical issues should not be overlooked since this can affect performance. The physical stability of Cat6a is essential to its transmission performance. Cat6a can be more sensitive to degradation of signal compared to Cat5.

These may be produced by the following:

Cable twisting generates signal reflection.

Excess insertion pressure on cables can cause poor connector performance.

Weakness of RJ45 (communications) connectors.

For example, if the cable is wedged in a door or compressed or squeezed by a heavy object, can result in sporadic network problems which may not be easy to detect. Nevertheless, Cat6a functions at enhanced specifications compared to Cat6 UTP. Considering all of these issues it may seem that fiber cable will become the ultimate future for 10 Gigabit Ethernet. It is up to users and the market forces to make the choice.
