Optical Variable Attenuator TW3305
is used with single-mode fibers. With its features of rugged design, portable, ease-of-use and good cushioning, TW3305 peforms just as well in a laboratory environment as it does in the field. In addition, the TW3305 attenuator has the inimitable function of displaying both the output and the input optical powers. It can be used as an attenuator as well as an optical power meter to ensure the complete set of functions with economic cost.
Features
- Wavelength, input power, output power, current attenuation and selected step size can be displayed simultaneously on LCD.
- On line Attenuation
- Combines the functions of both an attenuator and of an optical power meter
- Step size change of attenuation within a range
from 0.05dB to 5dB
- Optional Power Auto-off function
- Low battery power indication
