Optical bypass
An optical bypass is a device with inputs and outputs for different fiber types and connectors , the failure of a network component in linear or ring topologies , the data communication between the adjacent components maintains, as an optical relay the signals of the respective input is not at the corresponding output, but rather the second input. This means that a network remains functional even with multiple points of failure.
The switching threshold for activating the bypass function can be set within a certain voltage range. The time delay with which this function is switched off again after the error has been rectified can be set in stages. A bypass function can also be operated manually via a control contact.
