ABSTRACT:
A transmitting and receiving device for equipping optoelectronic communication systems with a metal case and a lead-in for a glass fiber through an outside wall of the metal case is disclosed. For such a device, a hermetically sealed lead-in for the glass fiber through the outside wall of the metal case shall be the result. For this purpose, the invention provides a metal tubing inserted in the outside wall of the metal case and a particularly designed metal ferrule-type connecting piece attached to the tubing. This combination results in an especially high-quality hermetically sealed lead-in for the glass fiber. The use of the transmitting and receiving device is advantageous in laser, transmitting, or PIN photodiode modules with so-called pigtail connections.
