Unique Properties of Fiber Optic Cabling

30 Dec 2014

Network Cabling ,Data Cabling, Fiber-optic cableFiber 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
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.

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.

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.

All About Cat6a Cable

11 Feb 2013

Cat6a Cabling in AtlantaIt was once thought that copper cabling would never support speeds above 1 Gig, but Augmented Category 6, or Cat6a - has proven that wrong. Copper still lives and copper cabling may still be around at 40 Gig.


There has been much debate about which is the better option for supporting 10 Gig: Cat6a Unshielded Twisted Pair (UTP)  or Cat6a Shielded Twisted Pair (STP)?  Both solutions have their uses, and some key information can help installers make informed decisions.



Standards and Alien Crosstalk


The IEEE released the 802.3an 10GBASE-T standard in June of 2006, which specifies 10Gbs data transmission over four-pair copper cabling. The Telecommunications Industry Association (TIA) then began work on transmission performance specifications for the cabling. They published TIA Standard 568-B.2-10: Transmission Performance Specifications for 4-Pair 100 Ohm Augmented Category 6 Cabling in February 2008.


The new Cat6a standard extends the frequency of Cat6a cables to 500 MHz with specifications for a new performance parameter called Alien Crosstalk (ANEXT). Cat6a cables are fully backward compatible with all previous categories, including Cat6 and 5e. NEXT is crosstalk that occurs between adjacent cables and connecting hardware. The higher frequency signals of Cat6a makes ANEXT the limiting noise source for Cat6 and Cat5e systems.



Cat6a UTP vs. STP


Due to its ease of installation and familiarity among installers, Cat 6A UTP is today’s cabling of choice as it can support future bandwidth needs and 10Gb/s performance. In addition, the shield n the STP cable helps prevents electromagnetic and radiofrequency interference (EMI/RFI) on twisted pairs, helping eliminate the effects of noise from sources like machinery, generators, or medical imaging equipment, making STP systems the  choice for industrial and healthcare facilities.


As most residential systems are not faced with EMI/RFI challenges, so UTP is still the recommended cabling type for home installations.

Cat5, 6 and 7 – What the Numbers Mean

2 Jan 2013

Category 6 Network Cable Twisted PairsCategory (Cat)5, 5e, 6 and 7 are different standards for cables used to transmit data through networks. All are twisted copper cables. The difference is based on their performance level.


Cat5 has become the world standard for connecting Ethernet devices. It is inexpensive and very effective; making it the most commonly used cable for connecting Ethernet devices. There are  two types, the Unshielded Twisted Pair (UTP), and the Screened Twisted Pair (SCTP).  SCTP adds a protective covering to protect against interference.  Cat5 is ideal For long distance communications as it is rigid and has the capacity to support 10-100 Mbps and 100MHz.
The gradual shift from standard 10/100 networks to gigabit networks has challenged Cat5 as it  cannot support high speeds. This led to an upgraded version, Cat5e.


Cat5e was developed to makeCat5 compatible with gigabit networks and provide extra protection from interference. However Cat5e does not completely remove interference, which results in slow and often poor performance, but Cat5e does makes networks more reliable and faster.

Cat6 is more advanced than Cat5 and Cat5e.  Like Cat 5 and 5e, it uses 4 twisted pairs of copper cables, but with much better performance. The difference comes from a longitudinal separator that keeps all 4 wires separate from one another, reducing interference or “cross talk”, and a faster rate of data transfer.  Cat6 can be used in any network that employed Cat5 and Cat5e. Cat 6 is the next level standard for Ethernet connection.

Cat7 is the next generation cabling device for Ethernet connections. It improves internal signaling and exterior protection over Cat5 and Cat6 and can support 10gigabit connections  adaptable to standard Ethernet connectors.
