Transmitter Optical Characteristics
Receiver Optical Characteristics
Notes:
1. The output power is coupled into a 1 m single mode fiber. Minimum output optical level is at end of life.
2. The relationship between FWHM and RMS values for spectral width can be derived from the assumption of a Gaussian shaped spectrum
3. These are unfiltered 20 - 80% values.
4. This meets the “desired” requirement in SONET specification (GR253). The figure given is the allowable mismatch for 1 dB degradation in re-
5. For the jitter measurements, the device was driven with SONET OC-48C data pattern filled with a 2
6. P
7. Spectral width of main laser peak measured 20 dB below peak spectral density.
8. It is recommended that an attenuator be added in the TX to RX optical loopback path.
