Why Your Company Should Avoid CCA Cabling – Part 1

22 Oct 2018

Cabling Network Cable Twisted PairsIf your company has a limited budget for network infrastructure, your team may be tempted to find numerous way to economize. Unfortunately, this may lead to buying CCA cabling in order to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets.



Definition of CCA


CCA stands for copper coated aluminum. A CCA cable’s core is an inner aluminum conductor that is coated with copper. As a result, it weighs considerably less than solid copper cables.


A CCA cable can be made at a significantly reduced cost than the solid copper version. This gives a manufacturer an increased profit margin and a significant competitive edge over those companies who continue making solid copper cable.


CCA cables may look similar and are advertised to function just like standard CAT5e or CAT6 cabling, but they have serious flaws that could result in network issues, business continuity problems, and safety hazards as discussed below.



Non-Compliant


CCA twisted pair cables are non-compliant with UL and TIA standards, which require solid or stranded copper conductors. The National Electrical Code (NEC) also does not provide CCA cabling a valid safety listing. Thus, CCA cables cannot be installed legally if the facility requires CM, CMG, CMP, CMR, or CMX rated cables.



Inflexible


As CCA conductors are brittle and easily break, just transferring a faceplate or patch panel can result in failures. CCA wires have low tensile strength, and they are known to break from shearing or pulling, which can happen during packaging or delivery. Moreover, CCA cables have a very limited bend radius.



Oxidation


Aluminum begins oxidizing very rapidly when it is exposed to air. This oxidation and the resulting corrosion may lead to failed terminations inside the network infrastructure, resulting in connectivity issues.


Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.

Top Ten Tips for Business Data Cabling – Part 2

22 Aug 2018

cabling, network cabling,Washington DCAs discussed in Part 1, business cabling projects can be a challenge to properly design, install, and accomplish on schedule. The key to success is finding an experienced team that will provide structured cabling services of high quality. Part 2 will discuss Maintaining Standards, Planning Well, Respecting Regulations, Staying Up-to-Date, and Testing Infrastructure.



Maintaining Standards


Maintain the established standards and best practices of structured cabling. Neglecting to do so will probably reduce quality and the efficiency of a data network. For guidance, refer to the standards set forth by the Telecommunications Industry Association.



Planning Well


Planning well will help future proof your organization. Do your best in estimating what your company will need for the next five years. CAT5E is now the standard, and it can support a maximum of 1000 Mbps. If your company needs more bandwidth, CAT6 is rated at a maximum of 10 Gbps. Re-cabling soon after installation will be disruptive and expensive.



Respecting Regulations


Compliance with codes, laws, and ordinances typically protects the lives of employees and first responders. A company found to be violating regulations will be fined and required to rewire the cabling so it is up to code. In the event of injury or death that is attributable to a violation, individuals found responsible may be held financially and perhaps criminally liable.



Staying Up-to-Date


Staying current with technological developments and regulations related to structured cabling and IT infrastructure will allow you to provide guidance to your company that has foresight. Knowledge of trends will let you anticipate what your IT infrastructure will need in the future.



Testing Infrastructure


Testing IT infrastructure during the installation of cabling is good practice. For efficiency, tests should be performed in phases to detect and fix problems quickly. Testing only after the installation of hundreds of feet of cabling will discover issues far too late and result in time wasteful revisions, repair, or replacements.

Gradual Phase Out of CAT5e Cabling in Office Buildings

13 Mar 2017

Class E (CAT6), Network Cabling, DCAfter their Milan working group meeting in 2015 regarding cabling standards, the International Organisation for Standardisation (ISO) and International Electrotechnical Commission (IEC), together known as the ISO/IEC, made the announcement that Category 5e (CAT5e) cabling will be considered obsolete for new installations in commercial and industrial buildings.


Setting the first international standard for cabling more than 20 years ago, ISO/IEC continually works on the development, maintenance, and promotion of technology and communications technical standards. A major change for the cabling of office buildings is now being implemented worldwide, raising the minimum horizontal cabling requirement from Class D (CAT5e) to Class E (CAT6), along with recommendations for installing Class EA (CAT6a) or faster cabling. Essentially, this will result in making CAT6 the minimum requirement for installations in new office building installations.


Providing a maximum performance of 100 MHz over computer networks, CAT5e has been utilized in structured cabling for both Ethernet and IP communications.  Considered adequate for fast Ethernet and gigabit Ethernet, CAT5e has the additional capability of carry video and telephony signals. The original ISO/IEC 11801 standard now has cabling classes that were added for enabling the support of up to 10 gigabits a second, such as CAT6, CAT6A, CAT7 and CAT7A.


CAT5 is not capable of matching the speed of data that CAT6 or CAT7 cabling can deliver. CAT6 has a maximum performance of 250 MHz, while CAT7 has a maximum performance of 600 MHz, enabling ultra-fast Ethernet. In addition, CAT7 features better durability and a longer service life than either CAT5 or CAT6 cabling.


More than 20 years have passed since ISO/IEC 11801 made its debut as an international standard, and it has led the way for the reliable implementation of data and voice cabling globally. However, CAT5e is now in the process of being phased out. Superior classes of cabling are being installed at new office buildings. Wireless LAN infrastructure is upgrading at a rapid pace, along with its speed, to keep up with the growing number of smartphones, laptops, and tablets. These demands have forced the gradual replacement of CAT5e with newer cabling that will meet current and future user expectations for fast and efficient data capability.

Are you Ready for 2gb Internet?

13 Jun 2015

Your city might be poised for a dramatic increase in Internet speed into your office. Right now, you might have DSL Internet running on Cat5e cable at speeds of up to 25 - 30mb. But 2gb Internet is coming. New high-speed fiber optic networks are being built that will bring 2gb Internet to your office's network. It's coming.



So, are you ready for it?



The answer to that question lies primarily in the cabling that exists in your office. Most offices in the US have Cat5e cabling. Cat5e is not even fully capable of handling 1gb speeds and will likely create speed issues at the desktop as users demand more bandwidth from advanced online and desktop applications. Cat5 cable is even slower. So, you will first need to figure out what kind of cable you have. The best way to do this is to look at the cable. Go to you wall closet or server room and look behind the patch panel. The patch panel looks like this.


And behind the panel is a bundle of cables. These cables have writing on them that describe the type of cable.That might look like this.





You should be able to see printed right on the cable the words "CATEGORY 5" or "CATEGORY 5E". If it says, "CATEGORY 6" or "CATEGORY 6A" than you are fine. Otherwise, you have cable that will not fully support 2gb Internet speeds into your office. Cat6/6A cabling is designed for 2gb and higher throughputs of data.


But getting ready for 2gb Internet is not just about the cable. You need the right cable and you also need the Cat6 compatible connectors, patch panels and a faster switch too. So, now you have a big decision to make.


















The Big Decision


What should you do? Recabling an office is a big deal. It's disruptive and it's expensive. But, wait. Is it really such a big expense and does it need to be disruptive? The cost of installing Cat6 cabling in an office is about $175 - $250 per drop. Each computer will need one drop. And you might have a few printers on your network too. So, the cost is about the same as a cheap computer monitor. And the boost in productivity will go on for many years to come.


Will it be disruptive? We can install new cabling in parallel to your existing network at night and on weekends. The switch-over is a weekend job too. Then we finish up by pulling out all of the old cable. That's called demolition. It might get a little dusty. But our team will do it's best to keep things as tidy as possible.


So, are you ready for 1gb Internet? If the service is available and you want a free on-site survey, contact us. We will be happy to come by and look at your office and prepare a Proposal for you at no charge and no obligation. If you aren't sure about the availability of 1gb Internet, contact us and we will find out for you.

Is it Practical to Use Cat6 Cable?

26 Apr 2015

cat 6,structured cabling, Data CablingData volume has grown extensively. Also, the processing capacity to users continues to get grow. Specialists in data management forecast that information production will be 44 times larger in five years with enterprises needing to process and safeguard 80 percent of the new data.



Data Cables


For these reasons, you might need to become more familiar with different types of cabling. There is Category 5 (Cat5) cable but it is only capable of transmitting 1000 megabits data rate per second on an Ethernet network. Transfer of data demands are increasing due to new and more sophisticated applications. That is why many companies prefer to work with Category 6 (Cat6) cables. Cat6 has a maximum data transfer of 10,000 megabits per second. Cat6 is also backward compatible which means your Cat5 connectors will plug i and work (at the lower speeds).



Future Proofing


Cat6 infrastructure guarantees that your system will be relevant well into the future. This allows users to easily cope with any modifications, new features or technological developments. The Cat5 standard has been used for a long time. However, your enterprise needs adequate bandwidth to handle these continuing and future changes. It is not merely a possibility or “let's say” situation. It is to be anticipated as the online experience continues to progress.


Demand for Cat6 escalates as the world-wide web is now offering premium video streams, online applications, highly-responsive and media-heavy portals.  If you decide to upgrade to a more reliable network, consider Cat6 cables. It is fast becoming the new standard in this industry.



Downsides


Cat 6 is more costly compared to Cat5e cables. On average, we are finding that projects cost about 20-25% more. This is because you are not guaranteed full speed unless all the components operate at gigabit speed. So, you need Cat6 cable, connectors, patch panels and Gigabit switches too. If one part is not rated as gigabit, the network will run at Cat5e speeds. Call or contact us to help you make this decision.


Nevertheless, experts say Cat6 will sooner or later surpass Category 5e.  And the initial upfront costs will pay future productivity gains for many, many years to come.

What are the advantages and disadvantages of Cat6 cabling?

7 Nov 2014

network cabling,cat6 cableAs the price of Cat6 cable has come down, the answer is yes. You get 500% more speed for about a 25% higher price. Unless you really just don't need more speed, go with Cat6.


Category6 or Cat6 cables have established standards for the Gigabit Ethernet. This variety is backward compatible with Category 5 and 5e as well as Category 3 cable. Cat6 facilitates computer networks by providing high-speed data transfer rates. Performance can be described as optimal if other components within the network are also running at gigabit speeds.



What are the upsides?


Cat6 is fast. It has the capability to handle maximum speed performance of 250 MHZ. The network includes Gigabit Ethernet along with 10-Gigabit Ethernet. With complementary routers, interface cards, switches, and patch panels a complete gigabit network is possible. Information Technology professionals are aware that Cat6 cable provides exceptionally fast network performance and gigabit speeds.


The composition is similar to Cat5 Cable. There are eight wires which are coiled together forming four pairs. With Cat6, each pair of wires is designed to be insulated from the others so it can produce twice the communications capacity of Cat5 and Cat5e. Cat6 cables plugs and ports are compatible to Cat5 and Cat5e. It may not have the same maximum speed of the computer cable but it will still function.


You can upgrade to Cat6 cable if your current network is not performing at a productive speed in retrieving and saving your data files. Even small enterprises are now thinking of installing this model because it is fast emerging as the industry standard.


However,  Cat6 cable is  more expensive. It will surely be a waste of resources in cases where greater data speeds are not needed. That is why some users opt for Cat5e which is less expensive while still providing splendid performance.


At the same time, you are not guaranteed 100 percent full speed. Sometimes, there is a misconception that purchasing a Cat6 cable will offer users the whole gigabit bandwidth on your network. The truth is Cat6 cable will only generate full speeds if all of the components in the network can function at gigabit speed. In case a single part (network card, patch panel, switch or connector) is not gigabit rated, the network may work at the slowest speed of the slowest component device.


You might be persuaded to buy Cat6 without really understanding if it will really produce the desired impact on the network. This is why it is essential to learn everything about the product before you make a decision.

CAT5E/CAT6 Cable Repair & Patching Techniques

15 Aug 2014

Network Cabling,Crimp Tool , Data CablingNetwork cables are said to be the “arteries and veins” of the communications network. The cabled system is a highly consistent platform for setting up infrastructure since the connectivity is very reliable. It is also easy to troubleshoot. However, it is not really fail-safe. Cables can get warped and sometimes snagged in ceilings. The connectors can also get broken if they are pulled to hard at the wallplate.


It does not matter whether it is Cat5e or Cat6. Cat6 is considered a better choice although, for some, cost prohibitive. When you look at it,

Benefits of Copper Cabling Solutions

4 May 2014

cable testing, Network Cabling ,Data Cabling ,cat6-cablingThe conventional process of copper cabling has been used for several years and is still preferred by many network cable providers and end-users. Companies like Progressive Office Cabling offer a complete range of cabling solutions in Cat5, Cat5e, Cat6a and Cat6, providing clients with high-quality cable as well as connectivity components. Progressive Office Cabling makes use of highly effective cable management systems and well-trained technicians for installation jobs. It also employs a web-based online project management system to guarantee proper implementation and monitoring of any project.




How Does Copper Cabling Work?


Installation technicians have to follow specific policies and standards, particularly when it comes to building structure concerns. There are several steps to follow with regard to installation. First, the cable should have the appropriate covering or insulation, which is normally made of PVC, Plenum, Ultra-Violet, or mold-resistant varieties. The cable is cut according to the needed length, and outer covers are removed before connectors are attached. Use the appropriate stripping tools for this purpose. Cables should be mounted as orderly as possible.


There are instances when installers have to use ladder trays and J-hooks, which are made for network cabling, or shoot nails into concrete ceilings using a tool that literally propels nails like bullets into the concrete surfaces. Network cables must be installed away from electric power lines, fluorescent lamps and industrial machines; the risk of electrical coupling can increase dependent on proximity and voltage factors.



Different Benefits


Copper cabling has multiple benefits and is the most effective conductor out there. Copper cables are flexible, which is especially advantageous if you are using electrical wires. It is necessary to bend the wire during installation, so you need something durable that will not easily break after a lot of twisting. Copper does not easily melt, so even if a sudden surge of current or overload takes place, there is no risk of burning or melting. At the same time, copper is not difficult to work on. The majority of electricians opt for copper wires because they can be stripped easily or pulled through rigid spots.


With regard to structured copper cabling, there is the Power over Ethernet benefit. This means that it is possible to run power through devices such as Wireless Access Points, surveillance cameras, and power phones. There is an emergency power supply that continues to power mission-critical devices even if electrical power conks out. Copper cabling supports modern technologies and facilitates the convergence of different applications. Hence, it is important that copper cabling is optimized for your requirements. That is why you should make sure to get the services only of experienced and trustworthy providers in the industry. Choose the provider that ensures customer satisfaction and warranty after installation.

Shielded or Unshielded Cat6 cable?

22 Feb 2013

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.
