Download a datasheet for the Yamasaki TVOA1 Variable Optical Attenuator (pdf, 95kb)

Accurate and Reliable

Yamasaki TVOA1 Variable Optical Attenuator is used for introducing precise amounts of attenuation into an active fiber cable. Attenuation can be adjusted in 0.05dB steps, it is suitable for use in PON, PDH, SDH, SONNET networks and also in systems using analog modulation (CATV).

Attenuation is shown on the LCD screen in both dB and dBm. On shut down the VOA1 stores your settings and attenuation stepping, so that next time you turn it on, the TVOA1 is ready to use with your previous settings.
