Abstract: An optical package includes a dual fiber termination having a first optical fiber end portion and a second optical fiber end portion. A collimating lens, spaced from the dual fiber termination, is configured for collimating and transmitting an optical signal emitted from the first optical fiber end portion and for converging a reflected optical signal onto the second optical fiber end portion. A mirror spaced from the collimating lens and having a reflective layer is configured and oriented for reflecting at least a portion of the emitted optical signal from the collimating lens back toward the collimating along a propagation path. A compensation lens is disposed between the collimating lens and the reflective layer of the mirror for correcting optical misalignment between the dual fiber termination and the collimating lens.

Abstract: A facsimile transmission method on the CDMA cellular networks is disclosed and includes the following steps. A data terminal having upper layer protocols of a PPP and above recognizes and stores a modem command until a facsimile modem in a base station is acquired, and requests the fax call caused by a modem dial command with dial number to the mobile terminal through a serial interface. The mobile terminal establishes a fax call with a base station based on the same call processing as that of a voice, and acquires the facsimile modem in a base station. After the call establishment between the mobile terminal and the base station, the upper layer protocols in the data terminal are initialized and negotiated with counterpart protocols in the said base station. The data terminal transmits the fax image data encapsulated by the upper layer protocols to the mobile terminal and the mobile terminal transmits it encapsulated and segmented by the lower layer protocols to the base station.
