Variable Attenuators with air gap insert loss which depends upon axial misalignment of optical fibers.
Attenuators are used for variable
suppression of optical signal in links.
Attenuator takes place of a standard
mating adapter between two plugs.
The
attenuation setting is continuously
variable and controlled by turning the
control ring while the connected plugs
maintain azimuthal orientation one
against another. Each device is made
from nickel plated brass and provided
with the special regulating key.
Variable
Attenuator – FM Adapter of FC style is
used when various attenuation on one
port is necessary. The attenuation
setting is continuously variable and
controlled by turning the control ring.
Each device is made from nickel plated
brass and provided with the special
regulating key. |
