The `transmission_main_example.py` script calls the `propagate` function in core module `request.py`, which in turn calls the `create_input_spectral_information` function in `info.py` where the ASE noise is \"hard-coded\" to zero. So the Tx OSNR is always infinite which does not seem very realistic (e.g. the Voyager transponder specifies Tx OSNR to 40 dB but I have seen other specifications as low as 32 dB)."},"comment":{"url":"https://api.github.com/repos/Telecominfraproject/oopt-gnpy/issues/comments/430026879","html_url":"https://github.com/Telecominfraproject/oopt-gnpy/issues/116#issuecomment-430026879","issue_url":"https://api.github.com/repos/Telecominfraproject/oopt-gnpy/issues/116","id":430026879,"node_id":"MDEyOklzc3VlQ29tbWVudDQzMDAyNjg3OQ==","user":{"login":"dutc","id":3922744,"node_id":"MDQ6VXNlcjM5MjI3NDQ=","avatar_url":"https://avatars3.githubusercontent.com/u/3922744?v=4","gravatar_id":"","url":"https://api.github.com/users/dutc","html_url":"https://github.com/dutc","followers_url":"https://api.github.com/users/dutc/followers","following_url":"https://api.github.com/users/dutc/following{/other_user}","gists_url":"https://api.github.com/users/dutc/gists{/gist_id}","starred_url":"https://api.github.com/users/dutc/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dutc/subscriptions","organizations_url":"https://api.github.com/users/dutc/orgs","repos_url":"https://api.github.com/users/dutc/repos","events_url":"https://api.github.com/users/dutc/events{/privacy}","received_events_url":"https://api.github.com/users/dutc/received_events","type":"User","site_admin":false},"created_at":"2018-10-15T21:49:52Z","updated_at":"2018-10-15T21:49:52Z","author_association":"CONTRIBUTOR","body":"Thank you for this feedback! @jeanluc-auge is putting together some comments and will provide feedback after the TIP Summit."}}
