Fiber Optic Cabling for Your Business – Part 1

8 Oct 2017

Technology,Network Cabling, cablesThe widespread use of fiber optic cabling stems from 1950s research. These studies eventually made transmitting visible images via glass filament possible. This new technology was eventually used for viewing instruments and remote illumination for surgery. Subsequently, George Hockham and Charles Kao successfully achieved data transmission through glass fiber in 1966.


Fiber optic cabling is composed of glass fiber filaments housed within insulated casing, and these cables were designed for long distance, large capacity, and high performance data networking and telecommunications. In comparison to wired cables, fiber optic has high-bandwidth capability and is capable of data transmission over longer distances. Due to these properties, fiber optic cabling is used for a great portion of telephone, internet, and cable television systems around the world.



Fiber Optic Advantages


Fiber cables provide a number of advantages that make them superior to copper cabling. Due to properties of high bandwidth and low-loss, fiber optic cabling can be utilized over much greater distances than copper cables. Fiber optic cables can run up to 2 kilometers for data networks without repeaters. This is because light can travel much further on fiber cable and still retain its strength.


Fiber optic cables have greater capacity. Through the use of multiplexers, a single fiber optic cable can have the same network bandwidth as several hundred copper cables. It is now standard for fiber cables to be rated at 10 Gbps, 40 Gbps, and 100 Gbps.


Although it has special shielding as protection against electromagnetic interference, copper network cable is still susceptible when numerous cables are close to each other. This is in contrast to the physical properties of the glass used in fiber optic cables.


Fiber optic is also safer to use than copper in volatile spaces, where sparks can lead to disaster. It also has the upper hand in terms of security because tapping fiber cable to steal data transmission is very difficult.


Part 2 will discuss how fiber optic functions, its two main types, and fiber networks.

The Organizations that Set Cabling Standards

27 May 2017

Data Cabling,Network Cabling,Atlanta GAThe TIA (Telecommunications Industry Association) and the ISO (International Organization for Standardization) are the primary organizations that oversee the development of structured cabling standards for the industry. Committees formed by the IEEE (Institute of Electrical and Electronics Engineers) provide assistance through testing and setting performance specifications for various standards.


Compliance with standards ensures the functioning of systems at specified levels, backward compatibility, and a greater selection of equipment will exist. General global recognition of standards permit utilizing equipment sourced from various countries inside computer systems. Requirements for the components of optical and copper cabling including cables, assemblies, connectors, cabling spacing and pathways, administration, field testing, and installation are standardized to make worldwide acceptance possible.


Technicians in North America typically use TIA standards, while the rest of the world uses ISO standards. Examples of organizations that set regional and national standards organizations are CENELEC (European Committee for Electrotechnical Standardization), CSA (Canadian Standards Association) and JSA (Japanese Standards Association). Their standards are generally compatible with TIA and ISO.


Different terminology used by TIA and ISO Associations sometimes cause confusion because they refer to the same item. For example, what the TIA terms as Cat5e is what ISO terms to be Class D. However, adherence to standards set by TIA and ISO ensure system cabling requirements are properly implemented in the categories below.




  • Insertion Loss – Decrease of signal strength down the transmission line.

  • Return Loss – Measurement of signal reflections on the cable.

  • NEXT – Near End Crosstalk Loss due to signal coupling.

  • Propagation Delay / Delay Skew – Elapsed time for signal to reach other end of cable or the delay between signal arrival at far end on slowest and fastest cable pairs.

  • ACR – Difference between insertion loss and NEXT.

  • ELFEXT – Identical to NEXT, but for cabling system’s far end.

  • PSANEXT / PSAACRF – Power sum alien crosstalk at near end / Power sum alien crosstalk at far end.


Due to ever-increasing data rates, the efforts of the standards organizations are assuming greater importance in terms of ensuring proper system design.

Data Center Cabling Best Practices – Part 2

13 May 2017

Cat5e Cat6/6a Cabling,Office CablingAs mentioned in Part 1, modern data centers must be flexible, scalable, reliable, and manageable, making best practices required. Part 2 will cover cabling for Modular Data, High Density/High Port Count Fiber Equipment, and Standards.



Modular Data


Increasing in popularity, modular cabling systems for fiber and copper connectivity introduces the plug-and-play concept, which simplifies cable installation and significantly decreases costs and labor. Typically, cables are factory-terminated and tested.


While modular cabling is less costly when the infrastructure is modified in-house, it will not be as flexible because of the possible required commitment to a vendor for ongoing compatibility.



High Density/High Port Count Fiber Equipment


When networking equipment gradually grows in density and port counts rise to several hundred, the proper management of the connected cabling will also require increased effort.


In the past, the direct connection of cables to individual ports of equipment with low port-counts was thought to be manageable. Unfortunately, the same task will be very time consuming for high-density/high-port-count equipment. Eventually, the addition or removal of cables directly connected to these ports will be almost impossible.


The utilization of Multifiber Push-On (MPO) cable assemblies featuring a single connector at one end of cable and multiple duplex breakout cables at the other end will ease cable management.


The concept revolves around pre-connecting high-density/high- port-count Lucent Connector (LC) equipment with LC-MPO fan-out cable to dedicated MPO modules inside a dedicated patch panel. Once completely cabled, this patch panel will work as "remote" ports. Ideally the patch panels should be located on top of the cabling equipment to facilitate access to overhead cabling. This method significantly decreases cluttering of equipment and cables, resulting in improved cable management.



Standards


The ISO (International Organization for Standardization) and TIA (Telecommunications Industry Association) are the main organizations that develop structured cabling standards for the industry. IEEE (Institute of Electrical and Electronics Engineers) committees do the testing and then set performance specifications.


Standards compliance makes sure that systems function at specified levels, allows backward compatibility, and a greater variety of equipment will be available internationally. Widespread global acceptance of standards allows the sourcing and use of equipment manufactured by different countries.


Color Identification and Naming Scheme will be discussed in Part 3.

Cable Management ,Data Cabling ,Cat5e, Cat6/6a Cabling

Overview of Cable Management Practices – Part 1

20 Mar 2017

Although the last ten years have been trending toward wireless, the wired industry continues to grow. For security reasons, military, tech, government, and financial organizations forbid data transmission via wireless on premises. SMEs (small and medium-sized enterprises) also consider wired communications more secure, and it is the medium used for delivering power as well.


The following will discuss the four main practices of cable management and their advantages and disadvantages. Part 1 will discuss Concrete Trenching and Floor Decking. Consult with experienced professionals to make your cabling project a long-term success.



CONCRETE TRENCHING


Mostly utilized within single-story buildings, concrete trenching is made up of channels carved into the concrete subfloor through which run cable and conduit. During construction, trenches are occasionally created during the concrete pour. However, they are must be cut into the concrete subfloor with a concrete saw.


After cable and conduit are laid, the installation of floor boxes is the next step. For safety, trenches may be filled with concrete after the electrical system is installed.



Advantages


A traditional method that is very well known, concrete trenches do not take up additional space for their installation inside a building.



Disadvantages


The installation of concrete trenching is comparatively expensive, and it is noxious and noisy. In order to install trenches and cabling, the building will need to be closed during construction. Structural engineers need to be consulted to ensure a building’s structural integrity. Companies leasing a building must also receive the approval of the property management firm. As the layout is “permanent”, additions and changes may also require the patching of trenches that are no longer needed.



FLOOR DECKING


Usually found within multi-story buildings, floor decking involves running electrical conduit through the ceiling underneath the floor that it will serve. Tunnels for the conduits are cut or drilled into the concrete, and space is provided to accommodate outlets and electrical boxes.



Advantages


A traditional method utilized in multi-story buildings, floor decking does not take up additional space. In comparison to concrete trenching, much less cutting of concrete is necessary.



Disadvantages


The process of installation during construction is very time consuming. The layout is quite inflexible, making additions and changes, such as the rerouting of cables, very difficult. These will cause disruptions and hurt business continuity as two floors will be affected during the process.


Part 2 will discuss Overhead Cabling/Cable Drops and Underfloor Cable Management.

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.

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 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.
