Note 1: Measured with PRBS 2 -1 test pattern @1250Mbit/s, 1310nm, ER=10dB, BER =10-12.
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.
