Transmitting receiving device with a diode mounted on a support
First Claim
1. In a transmitting/receiving device with a transmitting/receiving diode mounted on a support and with an optical fiber optically coupled to an optical window of the diode, where support is provided with a lead-in for insertion of the optical fiber, and the diode is mounted on the support so that the optical window of the diode is positioned at the lead-in, the improvement comprising said support mechanically connected to a circuit module and said optical fiber positioned over a positioning block which positioning block is also attached to said circuit module, and through said lead-in to said optical window, said optical fiber being permanently positioned and attached on said positioning block so that an end face of the optical fiber is a predefined distance away from said optical window, said lead-in having the shape of a cone so as to form a small and a large opening on a near and a far side respectively of said support and said diode being located on the far side of said support where the large opening is located, such that the optical fiber is positioned but not attached along the distance from the positioning block through the lead-in along its length to its end, the positioning block being mounted on the near side of the support sufficiently distant from the small opening of the support that a gripper or fiber manipulator may be introduced therebetween for optimizing the position of the fiber with respect to the diode optical window.

Abstract
Transmitting/receiving device with a diode and an optical fiber optically coupled to an optical window of the diode, where the diode is positioned on a support with a lead-in for inserting the optical fiber. For such a transmitting/receiving device the optical fiber of the diode can be easily and accurately adjusted and subsequently permanently positioned. The invention makes provisions for a cone-shaped lead-in with the diode located at the larger opening of the lead-in. This results in an especially easy adjustment of the optical fiber with respect to the diode. The device can be used in opto-electronic receivers having a so-called "pigtail" connection.
