The optical module testing phase is a pivotal stage that follows the packaging process, constituting a central element of the production workflow. The equipment utilized in this phase can be broadly categorized into two groups: general-purpose test instruments and automated test equipment.

As ASIC chips and optical modules become increasingly integrated, the need for processes like bonding is expected to diminish. Nevertheless, the testing phase is anticipated to maintain its demand, positioning it as a relatively scarce and inflation-resistant link in the optical module production chain.
