Abstract
There is provided a test device and a test method that combine both tunable OTDR and WDM power meter functionalities into the same integrated optoelectronic test hardware, such that the tunable OTDR and the WDM power meter functions share optoelectronic components, thereby reducing the hardware cost and the overall form factor and weight of the test device. With the proposed configuration, both tunable OTDR and WDM power meter functionalities may be provided via a single test port to be connected to the optical fiber link under test. By connecting the fiber to a single test port, the number of manipulations to be performed by technicians is reduced and two tests can be performed in a single connection operation out of the same test port.
