Directions in Telecommunications and Cabling

3 Apr 2015

 Data Cabling ,Network cabling, DCThe telecommunications industry continues to advance. And bandwidth demands will continue to increase. Meanwhile, conditions to convey considerable amounts of information quickly are changing. Applications including graphic information, technical modeling, video conferencing, and multi-level online databases will certainly increase bandwidth requisites. The bottom line is demand for higher transfer speed for information is expected to rise.

Properties for Cabling Systems

Two principal properties needed for cabling systems are performance and easy installation. Fiber and shielded twisted-pair provide stronger signals compared to Unshielded Twisted Pair (UTP) although these two lagging in client acceptance. The question is will UTP provide the appropriate bandwidth for modern applications?

Unshielded Twisted Pair

UTP is considered the most prevalent cable worldwide for telecommunications and networking. Cat 5e is the most popular and it long ago replaced coaxial cable which failed to keep up with more dependable and faster networks. UTP is also easy to install, develop and troubleshoot. Unshielded Twisted Pair cabling does not have any foil covering. It depends on twisted pairs inside the cable to prevent electromagnetic interference. UTP is used extensively for local area networking and comparable cabling configurations. Hence, installation is easier and less expensive.

Shielded Twisted Pair

Shielded twisted Pair (STP) features a metallic foil enclosing twisted wire pairs inside the cable. This is the safeguard against electromagnetic intervention which facilitates rapid data transmission. STP functions by drawing electromagnetic interference and counterbalancing this with grounded cabling. The drawback is that if the cable is not grounded correctly it loses the capacity to prevent unnecessary noise. STP is also larger and more sensitive compared to UTP cables. Expert cable installers use this cabling for industrial environments where adjacent equipment emit significant amounts of elctron-magnetic interference (EMI). Actually, UTP and STP can perform well if installed and maintained by efficient cabling providers.

Transmission is Essential

Transmission should be balanced. This is the standard for conduction of data using twisted cabling pairs. Separate protection for balanced twisted pairs is designed to enhance resistance and emission of the communication lines. The shielding method produces a conductive barrier that lessens these electromagnetic waves. It also creates a conduit for conduction so that currents and can pass data through without any obstruction. Shielding can be performed on individual pairs or as one set of pairs.

Designs of Optic Fiber Cables

12 Feb 2015

network cabling,Data CablingmOptical Fibre CableOptical fiber cabling is made up of a fiber core and a protective layer. The shield is typically coated with a polymer. 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

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.

About Ethernet Cables and Data Shielding

7 Dec 2014

Network cabling, cables,shieldingThe Ethernet network cable connects devices on a LAN (local area network) such as personal computers, switches and routers. These cables are typically Cat5 and Cat6. These cables provide the infrastructure that connects the PCs, printers, router/modem and other peripherals to a switch. The cables are made up of stranded or solid copper wires. Stranded wires are not as susceptible to fractures but are more difficult to terminate. Solid Cat5/Cat6 also is less susceptible to electrical interference. These shielded cables are made up of braided strands of copper wrapped in a polymer layer and spiral copper tape. The shield is applied across the splices.

An Ethernet cable can be compared to an electrical power cord in that it can only extend a limited distances because of the electrical transmission properties. Meanwhile, wireless technologies (Bluetooth and Wi-Fi or local wireless technology) have enhanced the reach of Ethernet in residential and enterprise networks. The standard Ethernet cable consists of four coiled pairs that terminate at the eight pins of the clipped connector or "RJ45" at both ends of  a cable. At the wallplate is simply the female end of the same connector. The cable is made up of unshielded (UTP) or shielded twisted-pair (STP) cabling.

Shielding is not selected automatically during installations. The answer is, it affords the protection required for certain environments although there are also some downsides. One is mass. The single-shielded cable made of Ethernet weighs approximately 12 percent more than the unshielded cable. The double-shielded version is roughly 30 percent heavier. You may be putting together dozens or perhaps hundreds of individual shielded twisted-pair cables along  a  ladders tray above the ceiling, under a floor, or at the back of panels. The aggregate weight of these cables can collapse the mounting bracket.

Cable flexibility is also an important issue. Take care when you pull the cables through  conduits. The cable shielding can make installation more difficult. The sole foil shield can crack while the sharp boundaries of the shield can scrape the insulation of individual wires. This can cut the wire and cause data transmission issues.

What are the shielding options?

You have a number of shielding choices in for your Ethernet network. The single-shielded cable has the lightest protection. Double-shielded cables contain a foil and plate shield. It can ensure better protection against electromagnetic or radio frequency interference and reduce issues related to cable relocation. High-flex industrial cables are fabricated and protected for uninterrupted applications. These have special jacket materials to address industrial and outdoor concerns.

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.

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 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 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.

About Fiber Optic Cabling

3 Apr 2014

Data Cabling, Fiber optic cableAn efficient cabling system is one of the prerequisites for a functional network and is considered to be an investment that will comply with your networking needs in the long term. Fiber optic cabling is the product of modern technology. This type of cabling conveys information from one location to another through pulses of light in an optical fiber. It is important for users to learn the advantages of fiber optics.

Fiber optic cables possess more bandwidth, or communications capacity, compared to metal and copper wires. This variety can transmit more information with greater reliability, which is one of the reasons for cable television and telephone providers to opt for fiber. The optical fiber also generates minimal power loss, thereby allowing longer transmission. Such cables are resistant against electromagnetic interference; they can operate in loud electrical environments because the interference does not have any effect on fiber cables.

Moreover, data moves at higher speeds since the fiber optic signal ensures that only a small amount of signal is lost in the course of transmission. Data is safe with fiber cables. It does not give off signals and is relatively hard to utilize. You will easily find out if the cable has been tapped or infringement has been made on the system, as this tampering causes the cable to give away light and causes the whole system to break down. Fiber optic cabling allows users to store electronics and hardware in a particular area rather than wiring cabinets with equipment.

Fiber optic cabling facilitates consistent transmission of data. The central part is fabricated from glass, an insulator, so that electricity cannot pass through. It is barely affected by ebb and flow of temperature, unlike copper, and can be immersed in water without any negative effects. Fiber optic is lightweight and thread like, but tougher than copper wiring. Specifications are a lot more than the copper cable. Although it is more difficult to terminate compared to copper, modern connectors make it easier to terminate.

The costs of fiber as well as other components are decreasing gradually but installation is more costly. Of course, fiber is more expensive than copper but it become more cost-effective in the long run due to less required maintenance, networking and downtime.

Practical users value their money. There may be certain downsides, such as installation expenses, but these are decreasing steadily each year. Fibers are also prone to damages because of the fine and smaller strands. Nevertheless, you can always institute safeguards that will address these points. Make it a point to determine the benefits of using fiber optic cabling.  Install the highest quality of optic fiber cabling that your financial resources will allow.
