An embodiment of the invention relates to a system comprising an optical device () and an evaluation device () for characterizing the optical device. The optical device comprising a 90&#xb0; optical hybrid unit () having a first and second optical input (EE) and at least two optical outputs (A-A) wherein optical output signals (So-So) leaving the optical outputs have optical phase differences between each other of 90&#xb0; or multiple thereof; a first photodetector (P) connected to a first optical output (A) and a second photodetector (P) connected to a second optical output (A), wherein the first optical output emits a first optical output signal (So) and the second optical output emits a second optical output signal (So), said second optical output signal having an optical phase difference of 180&#xb0; relative to the first optical output signal; and a first transimpedance amplifier (Tr) connected to the first and second photodetectors (P, P). The evaluation device () is characterized by a signal source () configured to generate a first and second intensity-modulated optical input signal (Sin, Sin); an optical phase shifter () adapted to phase-shift the optical phase of the second intensity-modulated optical input signal relative to the optical phase of the first intensity-modulated optical input signal; a measurement unit () adapted to measure the electrical output signal of the first transimpedance amplifier (Tr); and a control unit () adapted to control the optical phase shifter.

Method and system for characterizing an optical device

An arrangement including an electrical conductor track carrier and a component applied on the conductor track carrier. The component is a fiber-optoelectronic component and has: a housing, at least one electro-optical or optoelectronic component, at least one fiber-optic interface connected to the electro-optical or optoelectronic component, and at least one electrical interface for connecting the component on the conductor track carrier. The electrical interface has at least one bent electrical soldering connection element which is attached by one end to a base connection section of the housing base and extends from there laterally toward the outside so that the other end of the soldering connection element projects laterally and is soldered laterally outside the outer housing contour on the conductor track carrier. The soldering connection element is bent away from the base connection section so that the base connection section is at a distance from the conductor track carrier.
