Superior Computer Cable Installation

Article by Michael Nelson

Fiber optic cable is the fast medium for data transmission available today. It will replace all other existing forms of data transmission with the exception of wireless networking. Fiber optic cables guide light from one source to the end user, and while transmitting sends data through groupings of different strands. A receiver configures the data from the light signal to the proper form. This is done at the fastest rate possible. A common misconception about fiber optic cables is that they are more expensive to install and maintain than traditional copper wiring. Due in large part to the fact that fiber optic cables have a larger capacity, communication speeds are maximized, with less interference and clarity that you can see and hear.

The reliability of fiber optic cable is unparalleled. For those looking for superior computer cable installation, choosing a company that certifies a connection through fiber optics should be point #1. High-speed communications often depend on the cable, and the durability of transmissions through these types of cable is unmatched. With the reliability being greater than that of traditional methods, bandwidth increases to larger scales. This means that digital, high definition video and sound is easily transmitted better and easier to headphones and television alike. Whether you’re surfing the Internet or watching your flat panel television, you’ll notice that the clarity and definition of superior computer cable installation shines through with each image. This is not something that was easily done before modern times.

Although there are many different ways to connect computers to information, most use Cat 5 cables in home. These cables are compatible with optical cables and most ISPs are now using fiber optics. If you find that your company is not guaranteeing the use of these high end-wiring solutions, it might be time for a change. There are still some companies not using high capacity, signals and receivers, double check and make sure that you’re getting superior computer cable installation.

The most important part about getting the best cable installation possible is the fact that fiber optic cable can carry a strong signal over a wide distance. You can’t argue with results. The results of getting proper wiring over traditional methods is very important to getting the best quality voice, data, and video possible.

Cable companies that guarantee to meet NEC, TIA/EIA, and ETA specifications are the only companies that deserve getting customers. Make sure that you’re not duped into inferior promotions, make sure that when getting computer cable installation, the company offers good overall service, installation, and a guarantee that the wiring from source to your home has optic fibers, or else you’re going to find grainy results and interference of all types.

The Main Hardwares used for Installation of ADSS and OPGW Optical Cable

Article by Wendy Xian

Principle of Cable Hardware selectionAs All Dielectric Self-supporting Aerial Cable (ADSS) and Optical Fiber Composited Overhead Ground Wire (OPGW) fiber optic cable are made of brittle material , so it can not put too much strain. And fiber diameter is very small, so he ‘s tensile strength very weak .In choosing the cable hardware, the principle is not only to meet all the features and characteristics of the cable should be inclusive , but shall take into account the payment of grip strength with uniform , non-metallic sheath degradation , wear , vibration breeze , dancing , exceed the allowable bending stress and reverse parameters. Therefore, the general provisions is “Hardware’s squeeze should not exceed with more than two cables design limits , hardwares should not be designed for a range of diameters .”

The Main Technical Parameters for Selection1）Climatic conditionsTemperature（°C），The annual average temperature（°C），Relative Humidity（%），Thunderstorm days（Day），Ice thickness（mm），Wind velocity（m/s）。2）Electrical parameters of the systemVoltage（kv），Maximum system voltage（kv), Power frequency（Hz)。3）Cable parametersModels, cross-sectional area（m㎡），diameter (mm), weight (kg / m); nominal damage load (KN), permissible bending radius (mm), linear expansion coefficient (/ ° C); the average annual job tension ( KN), the maximum working tension (KN).4）Tower parametersTower type , model, each span (m), elevation (m).

The Structure and Installation of the ADSS & OPGW Cable HardwareLet me introduce the suspension clamps below:As the special requirements of ADSS and OPGW structure , when designed those products, it will adopt with more than 10 times of ADSS& OPGW allowed bending radius , with a damping function to reduce wear and the large curvature of the suspension clamps . The basic structure forms include pre- twisted wire , insulation and large curvature suspension clamps three types .1）Pre- twisted wire suspension clampsPre- twisted wire suspension clamp has the advantages of manufacture simple, easy to install , use effective, etc.Composed of four parts, there are preformed rod, rubber sheath , clamp body , hanging plate. The preformed rod used the aluminium alloy materials, through the preformed rod forming drawing mold forming in advance, front end is a smooth spherical, surface no crack, burr and serious wounds, forming aperture is ADSS and OPGW outside diameter 84% ~ 85%. Single diamete 2.5 mm to φ 6.3 mm is advisable.ADSS suspension clamp, has pre- twisted wire external and internal layers, inner diameter smaller than the outer diameter of single-1mm, length longer than the outer 20%~30%, gripping power is smaller than the outer 25%. Rubber sheath, with heart & bone and mindless bones two types. As the sheathed element for OPGW suspension clamps, it must have good damping properties, excellent fatigue resistance and therefore need good mechanical strength, appropriate compression stiffness, better resistance to oxidation and UV resistance, corrosion resistance, low degradation and OPGW greater starting hand grip, and starting hand grip relaxation speed (pressure decay) to be particularly slow. Only high polymer can meet these requirements, mainly with natural rubber and synthetic rubber as the main ingredient, and additive blending, reinforcing agents, plasticizer, etc, forming a multi-component synthetic rubber sheath. Because “Chloroprene rubber contains more unsaturated double bond, the ozone aging, resistance to oxidation and UV, weathering performance is poor. Design of rubber sheath thickness of 8~14mm, it’s length wrap for pre screen intermodulation formed from the long 80% or so.Clamp body is manufactured with high-strength aluminum alloy.Hanging plate tensile strength not less than 372.5N/ m㎡ of steel punching, hot-dip galvanized anticorrosion.2）Insulation type suspension clamps (also called FDS installations)Insulation type suspension clamps supported by shell, lining, bolts, devices (hoop or pendant bolts). The shell is used high strength insulating materials, lined is with a soft, flexible material.3）Large curvature suspension clampsOntology and plate thickness of contact surface on the part of the mosaic-4~6mm alloy. Aluminum alloy Board, the ontology uses, the rest of the steel products, hot-dip galvanized anticorrosion coating. Large curvature clamp trunking refers to ontology structures of curvature radius of curvature, curvature (Central slots for line segments, curves on either side) and two curvatures. Its curvature (bulk channel and plate) radius not less than diameter of OPGW 200 times and, of course, you can design a variety of different structures with large curvature suspension clamps, basic structure forms.

Performance comparison of 3 kinds of suspension clamps*Pre- twisted wire suspension clamps comparison1）Reduce the support points of inherent stress;2）Reduce the breeze vibration caused by dynamic stress;3）Enhanced hang point cable stiffness to avoid stress concentration, serve to protect the cable core; 4）Cable up to 60 ° angle;5）Easy to install;6）Higher price.*Insulation type suspension clamps 1）Structure is simple;2）Can sliding;3）Easy to install;4) Low price;5) Restricted the scope of use (span less than 25mm, <185m, cable diameter cable point ≤ 20 °).

*Large curvature suspension clamps1）Structure is simple;2）Low price;3）Installing the pressure plate bolt torque should be restricted;4）Only for OPGW, ADSS should not be used.

Installation points and method for three type suspension clamps installation*Pre- twisted wire suspension clamps 1）Upon installation, cable specifications, model, corresponding to the clip you want to install the selected one by one; 2）Check product quality; 3）Installation method, has normal type, bar type, with the grounding on the vertex type and double overhang corner double pendant and double cable type. Installation requires pre- twisted wire evenly tightened in cable, not too large gaps between single and overlap. 4）Cable angle 30 ° ~60 ° (horizontal angle and steering angle). Benefit is the increased stiffness, increasing the radius of curvature, guarantee that the core will not damage.*Insulation type suspension clamps Hold or fasten fixed with bolts.*Large curvature suspension clampsPressure plate bolt torque as designed for fastening。

As described above, when in selection of suspension clamps, recommended the pre- twisted wire suspension clamps, in terms of performance, quality, or on the installation convenience, is incomparable to the others. I hope the introduction above can give you some help when you choose the cable hardwares.If you want to see more info about the hareware, you can visit http://www.preformedline.com.

How To Guarantee A Perfect Fiber Optic Network Installation – Fiber Optic Tutorial Series 8

Article by Colin Yao

You can find many different fiber optic test equipment from major manufacturers such as fluke, Noyes, JDSU and many other suppliers. I will cover the ones you will most likely encounter in general service, installation and operation.

The basic fiber optic test and measurement tasks include optical power measurement, insertion loss measurement (attenuation), wavelength measurement, and even signal quality measurement. Some equipment directly shows the result while on others you would have to conclude your judgment based on the raw data they display.

:: Fiber Optic Power Meters

Fiber optic power meters measure optical power, which you can conclude from their name. They are composed of a fiber optic adapter, a silicon or germanium detector, signal amplifier circuit and a digital display.

Power meters come in two factors: desktop and handheld portable. In field service and installation, you will use a handheld type for sure. They can display measured optical power in two units: decibel or watts. They have to be calibrated for a precise measurement.

The most popular power meters are calibrated for 850nm, 1310nm and 1550nm, the three major wavelength bands for fiber optic communications.

You have to set up your wavelength before doing the actual test. This is very important since otherwise you would get a totally screwed up result for a different wavelength.

:: Fiber Optic Light Source for Power Measurement

Power meters are no use without a light source. A large variety of light sources are available for different applications and you must have the correct source for your measurement. Light source can range from several hundred dollars to tens of thousands of dollars depending on your testing requirement.

Light source can be divided into several major groups. Here are the major types on the market.

1. Broadband light sources

Broadband light source emits a broad range of wavelengths. The typical sources include tungsten lamps, LEDs and ASE (Amplified Spontaneous Emission) sources. They typical cover hundreds of nanometers.

Broadband light sources are major used in lab and manufacturing floors for spectrum performance analysis and not often used in field services.

2. LED sources

LEDs are widely used in field services as light source for multimode power measurement such as 850nm and 1300nm. LEDs typical emit a range of wavelength covering 50nm up to 100nm.

3. Fixed wavelength laser diode sources

Fixed wavelength laser diodes are widely used in field services. The typical applications include 1310nm single mode and 1550nm single mode systems.

:: Fiber Optic Talk Sets

Fiber optic talk sets are especially designed for installers working on a long fiber link at two points. Installers can use it to communicate and coordinate their work.

Basically what fiber optic talk set does is to turn any of the fiber links into a communication channel or telephone link. It includes both a transmitter and a receiver to send and receive voice signal through the fiber. Most fiber optic talk sets have headsets.

:: Laser Visual Fault Locators

Basically laser visual fault locators are a low cost red color laser source emitting red laser light ranging from 630nm to 670nm. When you inject that red laser light into the fiber, you can see light leaking on breakage points, defective splices, macrobending and other installation errors.

Laser visual fault locators emit much higher power than fiber continuity testers which use a LED red light source. So be careful to distinguish between these two equipment.
