There a few ways to source an optical module. The quickest one, source an optical module that is already in mass production from an optical module maker. In some cases, you may want to make some modifications to the optical module. For that case, you can work with an optical module maker to customize a catalog optical module to meet your needs; the optical module maker may require some commercial terms and conditions to support you as it may require tooling optical components. If your company has optics expertise, then you can design the optical module and find a company to manufacture it or manufacture it in-house. Also, you can contract with a third-party optical engine design house that can design the optical module for you, which can be manufactured by the design house or an optical module maker.

In some cases, the DMDs will include an optical module design guide that can help you understand the requirements for that specific chipset.
