Properly Installing Fiber Optic Cables

Properly Installing Fiber Optic Cables

Fiber optic cables are the industry standard for data transmission for telecommunications, computer networking, and home audio components. Due to their many benefits, fiber optic cables remain the prominent choice for video, voice, and audio transmissions.

A fiber optic cable can be installed for acquiring internet access from DSL, Satellite, Dialup and cable connections. A plentiful of amenities offered by fiber optics cable includes faster and reliable data transfer. Installation of fiber optic cable can be a troublesome task. But once properly installed, fiber optic cable has the capability of carrying light wave signals over a long distance in very less time. However if not installed properly, it cannot transfer any signals even from one portion of the building to another.

An appropriate installation requires a systematic knowledge and understanding of the potential and limitations of the cables. It also includes comprehending with the procedures involved while installing and maintaining the cables for their lifetime. The procedure of fiber optics installation involves certain concerns such as the cable must withstand the pulling force required to position the cable on to the right place, and also to the extreme natural conditions for instance hot and humid climate, cold temperature, underground moisture and much more.

It is always beneficial to do initial preparation and forecasting before actual installing the cables. The planning steps should insure the following things.

  • All the concerned parties for instance utilities or street department should be aware and endorse the positioning route for the cables.
  • While planning for saving cost the route should make use of the existing poles. The cable should ideally occupy the topmost space accessible for communications.
  • Proper distance must be preserved among the fiber optic cables and other electrical power cables where common poles are being used.
  • Determination of existing dead-end poles should be done beforehand to make sure the sturdiness of the poles.
  • Evaluation of splice location is done during the route survey of the cables. It is done to ensure the best possible use of continuous cable without much splices or joints.
  • In certain cases where aerial installation needs to be done the weather conditions should be good. It should not be done in drenched conditions. Each and every individual in the working unit should be aware of this.
  • The fiber cables should be properly positioned when there are other high voltage cables.

After assuring efficient planning and analyzing, the installation can be achieved in two different ways.

  • The first, a steel messenger is first of all positioned among the poles. In order to pull the messenger, a truck and a cable reel trailer are employed. To secure the cable near the messenger, a cable guide and cable lasher are used to enclose the cable in the messenger. The cable is made to form an expansion loop so that it allows for the expansion of the messenger at both the poles. The expansion loop length should be more than twice of the depth. The cable should be positioned in such a way that it maintains its least bending radius all the times.
  • The second is direct installation of self-supporting figure 8 fiber optic cable. This greatly makes things easier like positioning cables onto an aerial plant. This cable integrates both the messenger and the cable into sheathing like figure 8 cross section.

Tips for Fiber Optic Cable Benefits and Installation

Tips for Fiber Optic Cable Benefits and Installation

Fiber optic cable became the admirable source of long distance telecommunications in the 1980s. Today, the cable finds an unparalleled role in installing a variety of networks. Further more, the use of fiber optics for installations at homes and offices is increasing with time. However, it is extremely important to learn the right instructions for such installations.

Before the introduction of installation, let me show you some benefits of fiber optic cables.

The most attractive benefits of fiber optic cable is that it supports high bandwidth data transmission. The bandwidth value is extremely higher than that supported by other types of cables. The second is that the bandwidth capacity of these cables can be increased further using different multiplexing techniques. Another is the reduction in electromagnetic interference.

Rare chances of data loss during transmission are ensured by these cables. It means that they arrange for secure data transmission arrangement. Any fault in the cable can be easily detected. They are also resistant to damage caused by sparks and lightning. In addition, the cables are extremely durable and offer long term usage that adds to their cost effectiveness. Fiber optic cable is fast becoming a compliant medium of transmission and network set-up in different environments. They have definitely added a new chapter to the history of effective communication.

As compared to copper cables, those based on fiber optics technology are capable of offering many advantages. Though they have higher installation costs, but the long term benefits make their use in different applications acceptable. Here are some installation tips for fiber optic cable installation.

Firstly, it is important to know the types in which the fiber optic cable is available. While single-mode cables are useful for long distance installations, the multi-mode versions are apt for short distance applications. Simplex fiber optic cables will be used when a signal only needs to go in one direction while duplex versions are used in applications where data needs to be transferred bi-directionally. There are so many types of different fiber optic cables that it is suggested to obtain the variety which will be compliant with the equipments it will be connecting.

Once the cables are purchased, the next step should be to check them against possible damages. It is an important step considering the high cost of installing fiber optic cables. Visual fault locator based on red laser light is a tool that can be used for this purpose. There are two essential installation guidelines that must be followed. First, the pulling tension for these cables should not exceed the recommended value during installation as well as afterwards. Second, the bend radius of the fiber optic cables should not exceed the recommended value.

High pulling tension or exceedingly bent radius can permanently damage these cables. A number of tools can be used to ensure correct installation and strength member is one of them. The tool helps in attaining the right grip on the fiber optic cable so that its effective strength is utilized to the fullest. In order to protect the pre-terminated ends of the cable, another important tool called pulling eye must be used. A great deal of care must be taken to avoid scratching and twisting of the cables. The use of the best fiber optic connectors will enhance the worth of the installation.

Plastic Optical Fiber Transmission Principle

Plastic Optical Fiber Transmission Principle

Glass fiber has a dominant position in optical communication. But it has some fatal weakness including the low intensity, poor anti-bending performance, and bad resistance to radiation. For nearly 20 years, scientists have been looking for a new transmission medium and finaly they found plastic optical fiber as a medium is feasible in the light transmission and carried it out in real life for some applications.

Commercial products those are made of plastic optical fiber have been widely applied in some areas, such as lighting, information transmission. Even, plastic optical fiber has been able to replace the glass fiber in some areas. This article is about the transmission principles of plastic optical fiber.

POF (short for plastic optical fiber) has a step-type structure of the fiber core skin. Refers to the radial plane containing optical axes of the plane, called Meridian, is the propagation path of light which is always in the same plane. The radial light and optical axis is always the intersection of light propagation in a homogeneous medium that is a linear spread.

When light transmits from one medium to another medium surface, the general simultaneous reflection and refraction if the light from the refractive index of light thinning small medium large refractive index of light launches into dense medium. And when the light from the light launches into optical media thinning dense medium angle of refraction will be greater than the incident angle, so that when light from the light launches into optical thinning dense medium, it is likely to occur only when the medium without refraction reflection phenomenon, which is total reflection. Total reflection is a boundary effect of light refraction, for example, from one transparent medium into another medium in which curved phenomenon. POF is through the principle of total internal reflection of light transmission.

Only when the external light incident angle is less than 0, the light to the fiber by total reflection in the form of forward spread, spreads from one end of optical fiber the other end. So the critical acceptance angle of fiber 0. Therefore, total internal reflection-type is zigzag manner in SIPOF. As radial fiber is not the same incident light angle, Guer geometry in the fiber is not the same itinerary. Meridian in the light of both the trip times of reflection formula or formula, it is assumed that fiber is in very good condition. Fiber is straight, uniform diameter fiber, optical fiber and optical fiber within the defect-free straight face such incident. If the fiber did not have the ideal conditions, the incidence of radial total reflection would change the situation, if any, would be reflected out from the fiber, and some reflection angle would change and so on, so the fiber transmission loss will increase.

For graded refractive index GIPOF, also has radial and oblique light, this is not a constant optical constants of refractive index, but with increasing distance off-axis refractive index decreased; parabolic refractive index distribution mode optical fiber has low dispersion characteristics, reflects the distribution of various forms of gradient, when the refractive index distribution by quadratic parabolic distribution, the radial spread of the path in the fiber type for the sine curve, the spread of the light path inclined spiral curve , graded refractive index POF are used for short-distance data transmission, fiber optic lighting for small. This optical transmission of laser energy distribution close to Gauss distribution, that is, near the fiber axis there is a higher density of light energy which is more focused laser energy, the transmission of laser power density.

Advantages of Fiber Optic Cables Compared to Copper Cables

Advantages of Fiber Optic Cables Compared to Copper Cables

Nowadays, fiber optic cable has been more and more popular instead of the copper cable. However, these two different types actually have several different varieties of uses either in office or residential areas. Fiber optic is the latest technology in cabling or wiring system that allows you to get more advantages.

Copper cable is the older type of cable that has been used for over a hundred years in some different systems. You will find that this cable was traditionally used as telephone wire, speaker system wire, as well as computer wire. Copper cables contain a single thread of copper. The size will be quite different based on the purpose of the cable. It could be in thin or small size, but you can also find some types that come in large size as thick as your arm. Those are sometimes protected with a covering of another type of metal. The covering is usually called braiding.

What about fiber optic cable? It consists of plastic or glass strands to transmit information. Besides, it also transmits the data in form of light instead of electricity. A little bit different from copper one, fiber optic could not transmit electricity. However, this kind of cable offers higher theoretical performance. Besides, those two types of cable also have different resistance against interface. Copper cable usually is quite weak to some kinds of signal interface, such as those from cell phones or microwaves. Therefore, you should not operate or use any device that might trigger interface. However, you will not find this certain problem when you are using fiber optic cable.

There are several benefits offered by fiber optic cables. You might find some risks of interface from copper cable, but not fiber optic cable. Meanwhile, you will get great convenience from optical fiber since it could transmit multi-channel audio through a single line. This ability also makes this certain cable very popular for home theater system wiring. However, you need to pay more money to afford it.

Although compared to copper cables, fiber optic cables have so many advantages, they have good use in different areas. Copper cable is mostly used in Ethernet Network for short distance transmission, while fiber optic cable in the Optical Network for long distance transmission. You can choose the most appropriate one to support your own needs.
