The output power is coupled into a 1 m single-mode fiber. Minimum output optical level is at end of life.
Spectral width of main laser peak measured 20 dB below peak spectral density.
These are unfiltered 20 - 80% values.
This meets the “desired” requirement in SONET specification (GR253). The figure given is the allowable mismatch for 1 dB degradation in receiver
sensitivity.
For the jitter measurements, the device was driven with SONET OC-48C data pattern filled with a 2
P
72 ones and 72 zeros inserted. Over the range the receiver is guaranteed to provide output data with a Bit Error Rate better than or equal to
1 x 10
Beginning of life sensitivity at +25°C is -22 dBm (worst case).
IN
