ABSTRACT:
An arrangement in a fiber optic network device for analyzing a set of optical signals traversing the fiber optic network device is provided. The arrangement includes a set of ports for receiving and outputting the set of optical signals. The arrangement also includes a set of photodiodes, which is configured at least for receiving and forwarding the set of optical signals. The arrangement further includes a splitter, which is configured at least for receiving the set of optical signals from a first photodiode, splitting the set of optical signals into at least a first part and a second part, and forwarding the first part to a second photodiode and the second part to a third photodiode. The set of optical signals is configured to traverse the fiber optic network device irrespective whether power is provided to circuitry of the fiber optic network device.
