When an optical signal of a given wavelength travels in the fiber it looses power. The amount of loss of power per Km length of fiber is called its attenuation. A=10*LOG10(POUT/PIN) dB/Km Where POuT is optical power after 1 Km PIN is th epower launched in the Fiber.
An objective type of question on optical fiber is on that focuses on the integral part of fiber optic. A good question would be, " Why are optical fibers immune to EMI? "
Synchronous optical network (SONET)
Yes, they are the exact same thing
A fiber optical signal is based on the transfer of photons, while an electrical signal is based on the transfer of electrons.
what is fiber optics what is fiber optics
Bandwidth of an optical fiber determines the data rate.
A: Mostly for mullti channels communication

WDM wavelength division multiplexing
An optical fiber is a glass or plastic fiber that carries light along its length. Fiber optics is the overlap of applied science and engineering concerned with the design and application of optical fibers.

The optical fiber can be used both as unidirectional and bidirectional. The main application of optical fiber is in long-distance links, so there exists no need to employ them as unidirectional. For each direction different wavelengths are used to modulat the signals. At the same time many bidirectional signals can travel through the same optical fiber.
The electrical bandwidth refers to the frequency range that the electronic components in the communication system can handle, while optical bandwidth refers to the frequency range that the optical fiber can transmit. The relationship between the two bandwidths is important in ensuring that the data transmission is efficient and reliable. Matching the electrical and optical bandwidths helps to avoid signal degradation and distortion in the communication system.
OCDMA: Its nothing but Optical code division multiple access or Orthogonal code divsion multiple access..
how to design optical fiber link???????? . which coditions we have to keep in our mind in designing fiber network?????.in designing purpose which types of sours we will use & why???????????????????????
