ABSTRACT:
An optical module is packaged using one or more internal fiber connections which are arranged to minimize the likelihood of internal connection damage when the module is installed on a circuit board. The module includes at least one external connector arranged on a side of the package, and a submount within the package for supporting a component such as an optical source or an optical detector. An optical fiber is connected within the package from the submount to a connector interface of the external connector. The end of the fiber at the connector interface has a preformed connector thereon which engages a ferrule associated with the interface. The other end of the fiber is attached to the submount for optimal coupling efficiency. The fiber may undergo a bend of about 90.degree. or 180.degree. from its first end to its second end. In order to accommodate the fiber bend, the component submount is positioned within the package in a location remote from the external connector. The module package is particularly well-suited for use with optical transmitters, receivers and transceivers, but is also suitable for use with passive optical devices.
