ONET1101L: Application Inquiry

Part Number: ONET1101L

Hello Team,

Posting on be half of my customer.

We are creating a system of free space laser communication and looking into using fiber optic laser drivers to power lasers.  I have a few questions about the ONET drivers.  What is their modulation frequency?  It seems not to be specced anywhere.  I want to use them at lower speeds than they are designed for, so low modulation frequencies are ideal.  My other question is about using laser diodes with forward voltages greater than VCC.  Would this work, provided that the diode is AC coupled single ended?

Regards,
Renan
