Due to the use of fiber-optic cables and bandwidth requirements are different shapes. Multi-filament fiber cable contains several sopor fields, by the breaking of certain components of the strain and deflection are retrofitted. However, a threshold for each cable bending and withstand a maximum tension limit that must be observed during installation. Standard ANSI TIA/EIA-568B.3 bending radius of at least 1 inch and 2 inches without stretching for the stretched mode fiber is recommended. The maximum tension during installation Hdaksrkshsh equivalent to 2700 N and 890 N for the long term is recommended. One of the multi-stranded cables are common, with 24 strands, ribbon cable (Ribbon Cable) is. The outer sheath of the cable, PVC coating or asbestos or fluorine polymers are made. The fibers used in buildings and data centers are a major expense. Each ribbon cable with a connector MPT / MPO use. The flat cable makes cable installation cable passing through the interior tube site take more.
1 - Step Index Multi Mode Fiber: In this type Fiber Cladding Core frailty coefficient is significantly different sopor from the results when dealing with the cladding refractive index abruptly changes. These types of cables mechanisms cause the problem of broad Pulse shortening time are less used.
2-Graded Multi Mode Fiber: The fiber of this type occurs slowly when Prkhvrd radiation embrittlement coefficient of 50 to 62 micron Cladding border fragility coefficient reaches its minimum. And somewhat flattened portions of the control pulses to bring in, but the long-range deceleration faces.
Suppose, we are going to use a flashlight to illuminate a foyer and direct charges. Along with the bright light, the light emitted along the corridor Msfqym and it will clear. Considering the lack of bending or torsion in the corridor there was no problem with regard to light a torch and flashlight can be (given on the type) desired range brightened. If the corridor is a bend or twist, will deal with the problem?
Since the mirror cap layer around the core does not absorb any light, the light wave can travel great distances. However, some of the light signal while moving along the fiber, are low due to the presence of impurities in the glass. The purity of the signal degrades within sopor the fiber glass used, and also depends on the wavelength of the light within the fiber path (example:
To the knowledge sopor of how to use optical fiber communication systems, will follow the example that corresponds to a feature film or documentary about World War II. In the film, two Navy ships on the sea surface are moving, need to communicate with each other in a totally "are critical and windy., One of the ships are going to send messages to other carriers. Carrier of a message Captain For a sailor on the deck of the ship is based, is sent. sailor above the received message into a series of Morse code (dots and spaces) to translate. followed the sailor to post messages to use a spotlight carrier to another., a sailor on the ship, sending Morse code to see.'s sopor sailors continued the above code in a particular language sopor (eg "English) converter and sends them to the captain of the ship. Suppose the distance between the two ships Besar high (thousands of miles) and to establish the relationship between the use of a fiber optic-based telecommunications Sytstm.
Duty station, like the sailors sopor on the deck of the USS sender of the message. Received optical signal and optical transmitter device sopor to turn on and off in proper sequence (coherent motion) guides. Transmitter, the optical fiber is physically located in the vicinity and may have a lens to focus light in the fiber. Laser power LED are much higher. Their prices are also much higher than the LED. The most common signals of optical wavelengths, 850 nm, 1300 nm and 1550 nm
In communication systems, fiber-optic diode laser (Laser Diode (LD)) or LED (Light Emitting Diode (LED)) are used as the source of the carrier wave. Ideally, these light sources, waves are stable, single frequency and can produce enough sopor to travel long distances. Laser diodes, optical Vdyvdhay real Ideally different sopor ways. The diode in the frequency band of radiation that same problem with different wavelengths travel at different speeds, causing optical fiber chromatic dispersion (Chromatic sopor Dispersion) and Kshamdgy width of the signal received. A solution for dealing with the issue of creating distance between Pals hast. This reduces the data rate, which is mandatory, is desirable. However, certain pulses can produce this effect was totally eliminated the possibility of a pulse without a specific change to provide sopor distances of thousands of kilometers. The radiation power of the diode in the milliwatt range. However, due to the high sensitivity of these receptors may be sufficient in most cases. However, transmission losses can be continuously transmitted wave decreases and this is due to the communication link.
As already 'mentioned, some of the signals in the uplink data transmission distance is long (over a kilometer) and pure material for producing optical fiber (glass) is not used, will be weakened and the
