A communication apparatus configured to receive a communication parameter selects, when an access point itself is active as a providing apparatus or the communication apparatus detects an access point that is communicatable with an active providing apparatus, the access point as the access point to be connected using wireless connection. User authentication information sent together with an Internet connection request from a user terminal 5 relevant to a NAS 6 managed by an access provider, is transferred to an authentication server 7 managed by the provider. A pigtail fiber having a lensed fiber input end is positioned from the laser diode front facet to form an optical coupling region and is aligned relative to the lasing cavity to receive the first light output into the fiber, the light output exiting the package for coupling to the application.
