2. Optical attenuator - Wikipedia

   en.wikipedia.org/wiki/Optical_attenuator

   An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable.

3. Attenuator (electronics) - Wikipedia

   en.wikipedia.org/wiki/Attenuator_(electronics)

   Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching. In measuring signals, attenuator pads or adapters are used to lower the amplitude of the signal a known amount to enable measurements, or to protect the measuring device from signal levels that might damage it. Attenuators are also used ...

4. Attenuation - Wikipedia

   en.wikipedia.org/wiki/Attenuation

   Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam (or signal) with respect to distance travelled through a transmission medium. Attenuation coefficients in fiber optics usually use units of dB/km through the medium due to the relatively high quality of transparency of modern optical ...

5. Optical fiber connector - Wikipedia

   en.wikipedia.org/wiki/Optical_fiber_connector

   Connectors on polarization-maintaining fiber are sometimes marked with a blue strain relief boot or connector body. Sometimes a blue buffer tube is used on the fiber instead. [23] Hardened Fiber Optic Connectors (HFOCs) and Hardened Fiber Optic Adapters (HFOAs) are passive telecommunications components used in an outside plant environment. They ...

7. Π pad - Wikipedia

   en.wikipedia.org/wiki/Π_pad

   A Π-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers. A Π pad can be viewed as being two L sections back-to-back as ...
