does anyone have a teardown video? I want to see how it looks inside., :popcorn: |

You could design a small board with two SFF/SFP modules just wired to each other. To simulate the fiber being disconnected/reconnected you can toggle the TDIS signal of the SFF/SFP modules or enable/disable the 3V3 rail. |

The problem with active solutions is that they are protocol specific, and you cant cater for WDM. There are electromechanical optical switches available, they are also commonly used in protection switches to select between 1 of n paths in transmission systems, e.g. in case of a fibre break to select an alternate path for either the receiver and/or the transmitter. They are purely optical, no OEO, so you can pass what ever protocols or as many wavelengths as you want through them. |

I wonder if you could use a really bright source firing into the side of the fibre to saturate the receiver ? |
