Abstract
An example method includes dividing an optical communication channel to separate an upstream path and a downstream path, generating an interference signal to emulate rogue transmission behavior on the upstream path by connecting the downstream path to the upstream path, and undividing the optical communication channel, after generating the interference signal, by recombining the downstream path and the upstream path.

A method, comprising:
- dividing an optical communication channel to separate an upstream path and a downstream path;
- generating an interference signal to emulate rogue transmission behavior on the upstream path by connecting the downstream path to the upstream path;
- and
- undividing the optical communication channel, after generating the interference signal, by recombining the downstream path and the upstream path.

A device, comprising:
- a first signal separator connected to an optical communication channel to generate an upstream path and a downstream path;
- a first splitter on the downstream path;
- a second splitter on the upstream path and connected to the first splitter;
- and
- a second signal separator connected to the optical communication channel to recombine the upstream path and the downstream path, wherein:
- the first splitter and the second splitter are configured to connect the downstream path to the upstream path to generate an interference signal to emulate rogue transmission behavior on the upstream path.
