ABSTRACT:
This invention relates particularly to an arrangement for operating and testing in the field of optical communication networks and to an arrangement and a method for an operational test of optical devices, such as erbium-doped fiber amplifiers (EDFAs). The device under test is connected via optical fibers with a tunable laser and an optical signal analyzer. A pattern generator controls the tunable laser to generate a set of signals with different wavelengths .lambda.1 to .lambda.4, one after the other, within the recovery time of the device under test. Thereby, the operational behavior of a device under test, having a recovery time, and which is applied to several signals with different wavelengths present at the same time, can be tested by a single tunable laser.
