JDS FITEL VA47K PRECISION MANUAL VARIABLE ATTENUATOR

Description

Unopened in-box JDS manual precision attenuator. This is for single mode fiber calibrated for 1310 and 1550nm. The fiber connector is SC but can be used with FC/PC or FC/APC connectors, if you buy a hybrid patch cable from places like Thorlabs or FIS. It takes 9V battery to run the display (shows attenuation). I am selling un-opened sealed units from JDS. The one in the picture was opened just to take picture but I have other unopened ones.
I am an optics engineer so feel free to ask any technical questions.
