TRANSMITTER & RECEIVER 1dB COMPRESSION PERFORMANCE
Figures 13 and 14 show the 1dB compression behavior of the transmitter and receiver.
In Figure 13, it can be seen that the 1dB compression behavior of the transmitter is highly
dependent on the gain setting of the transmitter. The Figure shows the behavior at Maximum
Gain (25dB), Maximum-10 Gain (15dB) and Minimum Gain (0dB). The corresponding 1dB
compression points are -12.5dBm, -2dBm and +12.5dBm varying almost exactly dB per dB as
the gain changes.

Figure 14 shows the 1dB compression behavior of the receiver output. The test conditions are
minimum transmitter gain, maximum receiver gain and +3.5dBm optical input. The 1dB
compression point is +11.7dBm.
