Abstract

The invention relates to an arrangement for operating an optical transmission or reception module at high data rates of up to 10 Gbit/s, having a TO package with electrical connections, an optical transmission or reception module arranged in the TO package, and a circuit board for making electrical contact with the electrical connections of the TO package. According to the invention, the circuit board (

6) has RF lines (

81, 82) and the electrical connections (

41, 42) are connected to the RF lines (

81, 82) in an arrangement parallel to the plane of the board. Preferably, provision is also made for an RF matching circuit to be produced on the board and for SMD components to be fitted directly and without further solder pads onto planar RF lines on the RF board. The cited measures serve to improve the RF properties of a TO module.
