Notes:
1. The optical power is launched into 9/125um SMF.
2. Measured with PRBS 2³¹-1 test pattern @9.953Gbps, ER is measured with 4^th order Bessel-Thompson
filter ON.
3. Maximum sensitivity penalty due to transmitter and dispersion effect through 20km of SMF optical
fibre.
4. Measured with a PRBS 2²³-1 test pattern @2.488Gbps and ER=8.2dB, BER =10^-4, ER is measured
with 4^th order Bessel-Thompson filter ON.
5. Decreases in optical power below the specified level will cause signal detected assert output to switch
from a high state to a low state.
6. Increases in optical power below the specified level will cause signal detected deassert output to
switch from a low state to a high state.
7. Maximum reflectance of receiver module measured at receiver wavelength. Reflections from module
back to the cable plant
8. Optical Isolation and Cross-talk values given for design purposes.
