Notes:
1. Module circuit ground is isolated from module chassis ground within the module.
2. Open collector; should be pulled up with 4.7k – 10kohms on host board to a voltage between 3.15V
1. Module circuit ground is isolated from module chassis ground within the module.
2. Open collector; should be pulled up with 4.7k – 10kohms on host board to a voltage between 3.15V
and 3.6V.
3. Reference clock is single ended and requires a non-inverted input on PIN 24. Finisar recommends also
using the inverted input on PIN 25 for noise considerations. Version not requiring Host board
Reference Clock is also available upon request.
