| This is a device
whereby optical power level is controlled by the use of optical fiber of any attenuation.Since
we offer low-reflection type (return loss of more than 50dB ) it can be used under
a wide variety of conditions. |
|
 Features |
| |
Several connector shapes are available according
to the use and condition of installation. |
|
This device is an optical attenuator using
the metal-doped fiber. |
|
With small dependence on wavelength and polarized
wave,it has the stabilized optical characteristics. |
