For your consideration: Siecor 2001-DUALM-15 module for 2001HR-P OTDR. S/N 41541. Wavelength 854/1301 nm. Item was tested for power on and displayed a blank green screen. Unit appears to have been dropped on its back side, as the rear left fan is cracked (still spins) and one of the legs is loose. A perfect candidate for repair or parts.
