7.1 Optical Module Selection

There are a lot of optical module choices to select from. It is important that you know exactly what optical module you need to specify. You can read the TI DLP® Pico™ System Design: Optical Module Specifications to understand optical module specifications and other related system design considerations. After deciding what optical module specification meets your needs, you should document that specification to share it with optical module maker candidates. All of the terminology used in the example below are thoroughly explained in the application note.
