What is Fixed Fiber-optic Attenuators?

   Fixed optical attenuators used in fiber optic cable systems may use a variety of principles for their functioning. Preferred attenuators

use either doped fibers, or mis-aligned splices, since both of these are reliable and inexpensive. Inline style attenuators are

incorporated into patch cables. The alternative build out style attenuator is a small male-female adapter that can be added on to

other cables.
  

    Non-preferred attenuators often use gap loss or reflective principles. Such devices can be sensitive to: modal distribution,

wavelength, contamination, vibration, temperature, damage due to power bursts, may cause back reflections, may cause signal

dispersion etc.
