CONDITION:

Good cosmetic condition. LCD display is very clear. Internal fiber connectors are clear under fiber scope.

Variable attenuator is verified working very well at our lab.

At 1550nm with SM fiber jumpers, we tested insertion loss (including one-connector loss) with HP 81525A optical head:
Set 0dB, IL=2.485dB. (This is minimum loss)
Set 5dB, IL=7.357dB.
Set 10dB, IL=12.383dB.
Set 20dB, IL=22.425dB.
Set 30dB, IL=31.955dB.
Set 40dB, IL=41.671dB.
Set 50dB, IL=51.03dB (accuracy is limited by optical head).
