TRM-7100C

1. Minimum sensitivity and saturation levels at BER=1E-12 for a 2

µW is

approximately equal to an average power of -18.4 dBm, average with an Extinction ratio of 9 dB.

2. The current excludes the output load current.

3. These outputs are compatible with 10K, 10KH and 100K ECL and PECL outputs.
