SHF 46100 A
E/O Conversion ModuleDescription
The SHF 46100 A is a module which converts electrical signals to optical signals. The module is acompact, low cost solution which offers superb performance while including easy to use features.
An automatic bias circuit sets the modulator bias so that the output signal quality is optimal. It isalso possible to change the bias conditions so that the polarity of the output signal can be inverted.
Further details about the operation and use of the SHF 46100 A can be found in the Application
Note AN46100-1 (available in the Downloads section of our web site).
