The FHA2 Series Optical Variable Attenuator is a compact and portable instrument widely used in fiber link certification and routine maintenance, as well as in lab environments.
There are two models available in the FHA2 Series Optical Variable Attenuator, the FHA2S01 which has an attenuation range of 0-80dB and the
FHA2S02 with an attenuation range of 0-60dB.
The FHA2 can operate at both 1330nm and 1550nm with attenuation being simply set by key presses in either 0.05dB or 1dB steps. A reference value can be set allowing for easy recall and testing against defined parameters.
Operable either from rechargeable batteries or AC, the FHA2 provides a portable Optical Variable Attenuator that can be used both in the field and lab.
