 The D2-135-SMA requires an electrical signal input between 10 and -10 dBm of power.
-The D2-135-FC-800 is no longer available, but information regarding it is retained for those users who have purchased this model.  It includes a 10 GHz GaAs high-speed photo-detector for converting the input optical beat-note into a electrical beat-note. The maximum optical input power is 1 mW. //Warning: input powers  over 1mW of optical power can damage the OPLS.//  A minimum of 50 μW of power in the optical beat-note is required(( Note the power in the beat-note is not the same as total power. Because the optical input uses multi-mode fiber, the spatial mode overlap between the two lasers is not guaranteed. If the overlap between the two lasers is poor, there can be very little power in the beat-note despite large optical power. )).
