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.

Facts about Data Cable Testing

6 May 2015

structured cabling, Data Cabling,  cabling testerTesting always plays a vital role in the process of installing new cables or servicing existing ones. Regular testers for data cabling include length, wire crimper map, attenuation, return loss, and DC loop resistance.



Complex Cabling Needs


Cabling infrastructure requirements have become more complicated. More standards are being developed for cabling professionals in testing and troubleshooting copper and fiber cables. And there are special requirements as well as downsides in the implementation of new  technologies. From 10BASE-T to 100BASE-TX to 1000BASE-T and now to 10GBASE-T. It is now more crucial to keep in step with the most up-to-date techniques in cable testing too. In short, cable testing infuses a higher degree of assurance that installed cable links will attain the preferred transmission capacity for your data communications.



Cabling Tester Categories


Cable testing instruments have been manufactured with unique features for specific tasks. Costs, performance, and applications vary. These depend on the required functions. The three main functions are certification, qualification and verification. Although certain attributes overlap, each category answers a particular testing prerequisite.


Certification facilitates conformity to standards defines by the industry. These are instruments signal a “Pass” or “Fail” towards data testing compliance within standardized industry norms. These testing instruments will find out whether a cable link conforms to a category or class such as Cat6 or Cat5e. It is the last step required by most structured cabling installers towards approval of a new  installation.


Qualification determines if the existing cable is capable of supporting specific network speeds. This special class of testers is supposed to meet the up-and-coming requirements of network technicians who troubleshoot data networks. These testers perform checks to make a decision on whether a present cable link supports the requirements for fast or gigabit Ethernet. With these instruments, network technicians can identify and isolate cabling issues. While Continuity testers do not perform the series of tests set down by these standards and are not  considered certification tools.


Verification makes sure that cabling connections are correct. This type of tool performs a continuity test. It guarantees all wires in the cabling link have been attached properly to termination points at each end. For twisted pair cabling, there is an appropriate pairing of the wires. Such testing tools also confirm wire pairing and find out installation flaws such as split pairs. These can also help in troubleshooting by working with a toner to pinpoint a certain cabling link. These testing tools do not give out any information regarding bandwidth and data integrity.

Issues to Avoid with Cat6a Cables

22 Dec 2014
Network Cabling ,Data Cabling,CAT2 6A UTPA 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.

Cat 6 Cabling Advantages and Disadvantages

7 Nov 2014

network cabling,cat6 cableCategory6 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 definitely 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 considerably 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.

Advantages Of Using Cat6 Cables

22 May 2014

Cat 6Category 6 or Cat 6 network copper cabling is the preferred infrastructure for Ethernet, Fast Ethernet, and Gigabit Ethernet. It has a maximum performance of 250 MHz, or 500 MHz for the more contemporary Cat6a standard. This type of cabling may be utilized for a maximum distance (end to end) of 100 meters, or 55 meters for the 10 GBASE-T networks. Aside from support for higher performance, Cat6 includes more rigid specifications for crosstalk and system noise. Although Cat6 is anticipated to surpass Cat 5 and Cat 5e cabling soon, all three cable varieties are still widely used for network installations.



Fast and Credible Performance


Most IT experts recognize this type of copper cabling for its speedy network performance due to its ability to deliver gigabit data transmission speeds. It has a parallel structure similar to Cat5 and Cat5e. These copper cables have eight wires coiled as one to form four pairs. The major difference is that one pair of the Cat 6 cable wires does not touch the others, so it can produce twice the transmission capacity of the two other models.


It is also backward compatible. The plug and port of Cat6 cable is the same as the 5 and 5e models. Thus, it can be plugged into any outlet that supports these cables. For instance, you can use the Cat 5 connection for a Cat 6 cable although it will not produce the full speed of the Cat 6 cable.



Resistance to Heat and Flexibility


Copper cables are second to silver in terms of effective conductivity, but among non-precious metals, these wires can cope with a broader load of electricity with less need for insulation. Furthermore, copper cabling has more resistance to heat, which eliminates overloading problems. They are impervious to corrosion despite their shiny surface. Copper is also more pliable, so it can be twisted without the risk of splitting. In fact, copper is used in fabricating thick wires for applications where very thin wires are required. It can also be part of an upgrade if you are looking forward to a more optimal network. Copper Cat5, Cat5e and Cat6 are the industry standards for most small to medium sized offices.


There are certain problems that deserve consideration. Such as copper cabling failure in high-performance wiring systems. Users may also need to contend with poor component performance, such as bad cable segments or connectors that do not comply with specifications. However, these problems are frequently the result of human error. So the choice of copper cabling is  still a good one.

The Advantages of Fiber Optic Cabling

7 Apr 2014

Fiber optic advantages  Network Cabling, Data Cabling,cat5 cat6 cablingSophisticated technology has made it possible for the new generation of entrepreneurs to enjoy Cat5, Cat6, and fiber optic cabling. These technologies amplify speed, enhance performance and reduce costs.



Cat5


Cat5 refers to structured cabling for transmission of data signals. This is used primarily for computer networks. Standard performance is a maximum of 100 MHz and fits into the Gigabit and Fast Ethernet. Cat5 carries other signals for video and telephony. Almost all Cat5 cables are unprotected and depend on balanced lines and twisted pair designs as well as differential signals to reject noise.

Cat6


Cat6 is considered standard for Gigabit Ethernet along with network protocols that require more speed than Cat5 cables. Cat6 is made up of four pairs of wires comparable to Cat5. Using all four pairs allows this model to support communications that are double the speed of Cat5. This translates to speeds of one gigabit/second.

Fiber Optic Cabling


Fiber optic cabling or optical fiber is distinct from Cat5 and Cat6. It utilizes light rather than electricity to transmit signals. It has a better signal compared to the traditional copper cables, so it sends signals more rapidly than is possible with copper cable. Optical fiber is also impervious to interference from electricity, which means that users can use it anywhere and anytime. Fiber optic cabling also allows for much longer transmission distances. Cat5 and Cat6 are limited to only 100m of cable from wallplate to computer.

Even telephone companies have started to phase out copper wires in favor of fiber optic cables. Technical experts of these firms are working to reduce the vulnerability of fiber optic cables to water. Using fiber optic provides enterprises the adaptability of augmenting bandwidth in just several days compared to the conventional copper circuits, which usually take a maximum of one month to upgrade. Fiber optic connections generally start at two megabytes, with dedicated upload and download speeds of up to one gigabyte.

Fiber Connection


The fiber connection will also facilitate the business-mode Service Level Agreement or SLA. This implies that business entities obtain a secured 99.99 percent uptime. If power failure and other issues occur, technical specialists can conduct repairs within a maximum period of four hours. Your business reaps the benefits of speed, assured uptime and fast service by a reputable company like Progressive Office Cabling. It makes use of high-quality cables along with connectivity parts as well as the most efficient systems in cable management. The company’s technicians have been trained properly to be able to respond to your demands. With a proven project management approach, effective communication is guaranteed during the entire project.

This kind of service is practically unmatched in this industry. Savvy users and business proprietors will know how to choose the service provider that can deliver solutions based on their requirements.

Upgrade Comparison: Cat6a vs. Cat7 vs. Fiber Cabling Analysis

10 Mar 2014

We were asked to bid on a cabling project that was fairly straight-forward. It involved replacing the existing Cat5e cable with either Cat6a, Cat7 or fiber cable. The site was an open, standard modern office with a drop ceiling and hollow office walls. The client needed 64 single drops to existing faceplates, three new 24-port patch panels and patch cables.


The need for higher speeds by the client was created by a demand for faster access to larger files from the Server. This potential client was involved with heavy drafting and multimedia applications that require more bandwidth through the cabling system. Cat5e yields up to 1000Base-T, 1-Gigabit, data transfer speed.


The challenge is in deciding on which type of cable to use. Cat6a and fiber are very standard solutions. But Cat7 is not  at all a standard installation yet (and might not ever be one). The problems with Cat7 are that the cable is very heavy,
