Optical fiber is used to carry light ... either visible or else infra-red. So the source you want to use is a stable, reliable source of light, that's small enough to efficiently couple into the tiny window at the end of the fiber, and whose brightness can be changed easily and fast in order to put information onto the light (modulate it). It also helps if the light consists entirely of a single color (wavelength), because different wavelengths travel down the fiber at different speeds, so multiple wavelengths could get spread out and arrive at the far end in a real mess. The best, most widely used source available today is the laser diode.

How would you use Optical Link Budget to design short intermediate and long reach fiber networks?

An Optical Link Budget is the overall gains and losses within an optical network. Having this budget would than allow for the cost effective selection of transmitter, receiver (transceiver) at each end of a network.


How does fiber transmit data?

Optical fiber cables transmit light from one end to the other. The data is encoded into this light beam and travels down the fiber in this light. Obviously you need optical sensors at each end to get the information in and out.


How a scratch outside of an optical fiber might cause problems?

Fiber optics, using optical fiber, are specially designed to implement total internal reflection. A signal passed from one end of the fiber to the other end of the fiber is a single beam of light that repeatedly bounces off the edges of the fiber until it reaches it's destination. By scratching the outside of an optical fiber, this property can be disrupted causing the signal to be lost.


How must an optical fiber be designed so that light can be shone in one end of the glass and not leave until the opposite end is reached?

An optical fiber needs to be engineered with a high refractive index core surrounded by a lower refractive index cladding. This design ensures that light entering the fiber at a shallow angle is continuously reflected off the core-cladding interface through total internal reflection until it reaches the other end of the fiber. This prevents light from escaping and allows it to travel effectively through the fiber.

What is the Principle of optical fiber?

Fiber optic cables containing silica called filamentous crystal crystalline silica is actually the main component of these filaments heap on the inner wall can be attached to the wire with the wire bent over bent when the optical signal from the wire the optical signal to one input of the specular reflection on the surface of the silica on the principle of reflective transmission until it reaches the other end of the optical signal conductor recognizer so far. Fiber is divided into the following two categories: 1) transfer points modulo class Transfer points modulo class of single-mode fiber and multimode fiber. Single-mode fiber core diameter is small, at a given operating wavelength only in single-mode transmission, the transmission frequency bandwidth, transmission capacity. Multimode fiber is given in the operating wavelength, can be transmitted simultaneously to a plurality of mode optical fiber. Compared with single-mode fiber, multimode fiber transmission performance is poor. 2) refractive index distribution type Refractive index distribution type optical transitions can be divided into optical fiber and tapered optical fiber. Hopping optical fiber core refractive index and the refractive index of the protective layer is a constant. And a protective layer in the core of the interface, the refractive index changes stepwise type. Graded refractive index of optical fiber core increases as the radius decreases according to certain rules, and the protective layer of the core is reduced to the junction of the refractive index of the protective layer. Similar to the refractive index of the core changes parabola.


What is optical communication?

An optical fiber is a flexible, transparent fiber made of very pure glass (silica) not much bigger than a human hair that acts as a waveguide, or "light pipe", to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.

What are the Elements of optical fiber communication link?

If light meets the inner surface of the cladding (the core - cladding interface) at greater than or equal to Qc then TIR occurs. So all the energy in the ray of light is reflected back into the core and none escapes into the cladding. The ray then crosses to the other side of the core and, because the fiber is more or less straight , the ray will meet the cladding on the other side at an angle which again causes TIR. The ray is then reflected back across the core again and the same thing happens. In this way the light zig zags its way along the fiber. This means that the light will be transmitted to the end of the fiber. In reality the light which enters the fiber is a focused beam, consisting of many millions of "rays" behaving in a similar way. They all zig zag along the core of the fiber, crossing over each other, and filling up the core with light. A pulse of light traveling along the core of the fiber is really a bundle of these rays.


What is Optical line terminal?

An optical line termination (OLT), is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: - To perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical network. - To coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units).


Can optical fiber be used where ever co-axial and twisted pair are used?

In principle, not necessarily in practice. You also need an interface on either end that understands the protocol and can translate the optical signals to electrical ones.For the most common Ethernet standards, 100 Mbps and Gigabit, there are optical fiber versions of the standards, so the interfaces are available. If you are referring to a protocol other than Ethernet, you need to check for that particular protocol.On the computer end, you would normally swap the existing network card with an optical version (available for PCI-E and PCI-X slots, meaning most post-2005 desktops and servers).On the router/switch/hub end you could switch to an optical model.Standalone adapters are also available.So I suppose the answer becomes "no, not wherever, but in a quite wide range of cases".
