Fibre coupled variable attenuator (VOA)
VOA
is fiber coupled device easy to work with any application . It features low insertion loss,
wide attenuation
range, small package and it is easy to operate. The attenuation range is
from 0 to 40dB, and is continually adjustable. They come with single
wavelength and dual wavelength. Variable optical attenuator can supply
with FC/UPC, FC/APC, SC/UPC, SC/APC or LC connector types. |
- Wavelength: 1310/1550nm
- Singlemode SMF28 fibre
- 0.8~40dB variable range
Fibre coupled fixed attenuators (in-line)
-Singlemode
