1)
Minimum average optical power at which the BER is less than 1x10
–10
. Measured with a 2
23
–1 NRZ PRBS.
Worst case receiver sensitivity at 25°C is –31 dBm (beginning of life).
An increase in optical power of data signal above the specified level will cause the Signal Detect to switch from
a low state to a high state (high active output).
A decrease in optical power of data signal below the specified level will cause the Signal Detect to switch from
a high state to a low state.
Load is 100
differential.
Measured under DC conditions at 25°C. For dynamic measurements a tolerance of 50 mV should be added.
Only for V23818-C18-L3x/L436.
