Abstract
A system containing an improved adapter for passively aligning an active device such as a transceiver with an optical fiber having a 100 to 250 &mgr;m core is provided, such that the resulting coupling is within alignment tolerances, and provides desired coupling efficiencies and bit rates. In one embodiment, the system contains a packaged active device having a window or a lens, an optical fiber having a core of a diameter ranging from 100 to 250 &mgr;m, and a fiber connector attached to an end of the optical fiber such that a fiber endface is provided. The system further contains an adapter comprising a first receptacle that secures the fiber connector and a second receptacle that secures the packaged device, wherein the exterior of the device package, in combination with the second receptacle, itself provides passive alignment within the adapter.
