Note 1: Measured with a PRBS 2 -1 test pattern @1.25Gbit/s and ER=10dB, BER =10 .
Note 2: See Figure 1,2. For multiple ONUs application, It isn’t easy to test TSETTLING directly, but there is a
relationship TSETTLING = TGAP-TGUARD when TON=TOFF, then TSETTLING can be calculated by TGAP and a certain
guard time at ONU side.
Note 3: See Figure 3. TGAP be less than 250ns is guaranteed.
Note 4: An increase in optical power above the specified level will cause Signal-Detected (SD) output to switch
from a low state to a high state.
Note 5: A decrease in optical power below the specified level will cause Signal-Detected (SD) output to switch from
a high state to a low state.
Note 6: LVPECL output, DC coupled internally, guaranteed in the full range of input optical power (-6dBm to
-31dBm) (See Recommended Interface Circuit)
Note 7: SD (See Pin Function Definitions)
