Note 2: An increase in optical power above the specified level will cause the Signal Detect output to switch from a
low state to a high state.
Note 3: A decrease in optical power below the specified level will cause the Signal Detect output to switch from a
high state to a low state.
Note 4: LVPECL output, AC coupled internally, guaranteed in the full range of input optical power (-3dBm to
-27dBm) (See Recommended Interface Circuit)
