Abstract
Techniques are disclosed for filling gaps formed between a press-fit component and an optical subassembly housing to introduce a seal or barrier that can prevent or otherwise mitigate the ingress of contaminants. In an embodiment, a layer of sealant material is applied to one or more surfaces of an optical component prior to press-fitting the component into an optical subassembly housing. Alternatively, or in addition to applying sealant to one or more surfaces of an optical component, a layer of sealant material may be disposed on an interface formed between an outer surface of the optical subassembly housing and the optical component press-fit into the same. Techniques disclosed herein are particularly well suited for small form-factor optical subassemblies that include one or more optical components press-fit into openings of a subassembly housing during manufacturing.
