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.

Comparing Cat 7 to the Other Cats

3 Mar 2017

Data cabling, network cablingNowadays offices and homes utilize either a wireless (Wi-Fi) connection or wired network connection. Usually faster than Wi-Fi, wired connections also have lower latency. These two types of network connection continue to progress technologically, providing users ever increasing speeds.


In the case of home networks, the speed of the internet connection is typically the issue, and the cabling may not be a factor. However, a company must consider the specifications of particular cables and how these would meet its requirements in order to properly decide which to select. There can be a vast difference between the network speeds of the various Ethernet cables.



Types


Cables are differentiated by standard categories. Category has been abbreviated to “Cat” by the industry. Currently, the most common cables in use are Cat 5, Cat 5e, Cat 6, and Cat 6a. The newest type is Cat 7. Every type is backward compatible, allowing users to insert a newer cable into a device that was manufactured for an older cable without any compatibility issues arising.

Progress


With every new cable category, users were provided increased speed and decreased crosstalk. Newer category cables provided faster speeds at increased lengths of cable. The following offers comparisons at 100 meters of cable, illustrating the differences between the ethernet cable categories:

Cat 5 - Considered slow and inadequate for business networks, providing up to 100 Mb/second at 100 Mhz.

Cat 5e - provides up to 1 Gb/second internet speed at 100 Mhz.

Cat 6 -provides up to 1 Gb/second, and cable lengths up to 55 meters can give internet speeds of 10 Gb/second at 250

Cat 6a -can provides speeds up to 10 Gb/second, to 100 meters of cable length, at 500 Mhz.

Cat 7 - provides speeds up to 10 Gb/second to 100 meters of cable, at 600 Mhz.

History


Cat 5 was the standard in 1995, Cat 5e became standard in 2001, and Cat 6 was introduced in 2002. Arriving in 2008, Cat 6a is typically the newest cable the majority of companies have used because it is not considered necessary to update to Cat 7 yet. Cat 7a and Cat 8, which were respectively released in 2010 and 2013, are still waiting in the wings.

What is Certification and is it really necessary?

10 Aug 2015

Environmental Problems with Cat5e, Cat6, and Cat6A Cable


Cable must be installed so that external environmental factors do not have an effect on the performance of the network. Problems can occur at the patch panel punch down, at the wall plate jack and anywhere along the cable itself. Maybe an inadvertent kink is in the cable. Or there is a snag in the cable as it got pulled across a rough surface in the rafters above the drop ceiling. Or maybe the cable got too close to an electric line. Any one of these issues can degrade the performance of an individual cable.


There are two basic kinds of testing that is performed during the installation of cabling:




  1. Continuity Testing

  2. Certification


Continuity Testing



Continuity Testing is a test to insure that the wires in the connectors at the faceplate and at the patch panel are connected up correctly. There are 4 pairs of wires and each wire is color-coded. So, as the technician is connecting everything, a particular sequence is required. If a wire is connected in the wrong order, the cable will fail. This is a basic wire-mapping test. If this test fails, the connector and wires are re-examined and re-terminated. All of our cable installations include continuity testing.


But the only way to insure and guarantee full speed to every cable is to do Certification Testing on each cable.



Certification



Certification Testing is a performance test that utilizes a precision device that sends a signal from one end of the cable to the other. This test is the only way to test the data-carrying capacity of each cable. For example, Cat6A cable is rated to run at 10G/sec. But if you have an issue, the cable will work but it might be running at a slower speed. It passes the continuity test but it's not performing at 100%. Certification will find the fault, pin-pointed to its exact location so that our technician can fix it, retest it and fully certify it as 100% top-speed rated.


The Fluke DSX-5000 is a very expensive test device that we employ to test and certify our cabling jobs. It costs about an extra $10 per cable to get everything tested and certified. But without this test, we can't guarantee top speeds throughout your network. And, considering that most cabling projects have a useful lifespan of 15 - 20 years, this investment upfront is very cost-effective. It means you will have full speed to every device for the entire lifetime of your cabling infrastructure.


Certification includes a PDF report showing every cable and the test results.

Cable Basket Trays – Uses and Benefits

25 Jun 2015

Cable basket trays are described as go-to solutions for routing and supporting numerous cable runs. The wired frame Structured cabling, Data Cabling, DC enhances air circulation and cable ventilation. This can be appropriate beneath desks, elevated floors, or hanging tray systems. You can assemble basket trays for intersections, horizontal sections, mounting braces, hardware, and tray cutters.


The cable basket tray made of welded steel wires is considered the most popular support for copper and data cabling. The basket is light-weight and easy to install with complete array of cable tray accessories. Solid basket trays are recommended for heavier wires. These baskets are fabricated to withstand natural elements. Although the material is not solid steel, it is capable of protecting cables from corrosion and last longer.



Cable Distribution and Management


The cable basket makes possible efficient dispersal and management of cables. This process is accomplished by arranging cables inside the basket trays instead of pulling them through pipe lines. The act of yanking is certainly harder and time-consuming rather than using baskets. Laying down wires in the basket take only minimal time and ensures that cables are distributed evenly around the structure.


The baskets can be stretched along the building just like pipes. However, baskets are open facilitating easier access to the cables. At the same time, it provides sufficient protection to the network cabling system. Cable baskets are lighter with easier functions compared to trays which are quite bulky. Technicians can finish more installations in one day because of fast installation.



Installation Guidelines


Incidentally, it is important to make sure that cable trays should be installed as an inclusive system. The tray should be complete with all the supports mechanisms, fasteners, guards, connections, flexible vertical and horizontal spice plates. You have to mount cable trays so the joints will be accessible for inspection and modification. Support systems are needed so the distance does not go beyond the required measurements. Install intermediary support devices in case the weight of the cable is more than tray rungs’ load capacity.


Erect supports from channel members, twisted rods and other accessories provided by the cable tray manufacturer. Organize the supports in bar or wall-bracket models as called for by the application. Make sure to take away sharp border s from cable trays. You can attach the tray to the spice pates but use square neck-carriage bolts and self-locking nuts. The cable tray should support the building structure. Finally, mount the cable trays with sufficient space to allow access for the installation of network cables.

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.

Cable Network Trays as Support Systems

12 Jun 2015

cable network trays, Data CablingCable trays for networks are support systems that can be mounted on walls or hang up from ceilings. The trays are fabricated from aluminum or steel. These come in deepness of 2, 3, 4 and 6 inches. There are also multiple designs like trough (single rail), ladder, basket, and wire-mesh. The single rail is designed either with single or several options.



Types of Trays


The solid bottom trays support delicate cables. On the other hand, the center spine model is made up of a central support mechanism supporting the cable with the tray dangling from rods. This tray is important to the data communications market. The single-rail variety mounted on the wall is similar to center-spine. However, the treads can be found only on one side. Wire way is a system that is fully enclosed and provides no access to cabling inside.


Locations where cabling trays are required as well as cable types these carry have evolved during the last two decades. Cable trays are installed not only in power plants and paper mills but also in government facilities, schools and call centers. Certain manufacturers supply product categories produced for installation with uncommon requirements. For instance, the cable tray should be very robust so it can link a span of 30 feet between support systems. The short span variety supports four to five feet or limited space requirements of newly-installed components. Problems are resolved by using different types of cable trays.



Product Selection


The key to this is careful product selection since a single tray will not fit into all requirements. This offers the perfect solution. The main consideration is there are various instruments in the tool box of cable trays. You only need to match up each application for the ideal solution. Right now, there is an increasing need for big-sized trays so it will be possible to add more able in the future.


Modern installations entail manufactured support systems that can effectively hold both Category 5 and 6 cables. While cable performance becomes more efficient, cable and connector makers are also offering warranties for their performance. Along this line, the appropriate cable tray is needed so that cable performance will not be adversely affected by improper cable management.



What are the Benefits?


Contemporary cable trays have multiple benefits. These include the capacity to carry heavy weights. Installation is also faster and less complicated with reduced fitting time. Fixtures like risers, reducers and bends may be built on site. The applications have also expanded to several sectors such as industrial, infrastructure, commercial, food, and data hubs.
