OTDR Viewer is a desktop application which allows you to open and display information from Bellcore SOR files.
It's currently at an early state, but can display key events, traces, and other information from SOR files.
OTDR Viewer uses the otdrs library to decode SOR files and extract information in a standards-compliant manner.
The application itself is a Rust based desktop app using the Tauri framework, and uses the Vue Javascript framework to do most of the work involved with displaying traces.
OTDR data contains numerous vendor specific quirks about data storage and interpretation.
Currently, no management of these quirks is implemented. As such, data may not be accurate in the sense of your interpretation matching the vendor's. However, OTDR Viewer attempts to be as accurate technically as possible; maths is mostly done in Rust for performance and precision, and data is generally passed through without alteration other than that required by the standard.
See the otdrs docs for more information on SOR file parsing.
If you want to hack on this, great!
Install npm or yarn and Rust (e.g. with rustup).
Install the Tauri CLI with yarn add -D @tauri-apps/cli or see the Tauri docs.
After this you should be able to run yarn tauri dev to run the app from git.
The underlying otdrs library does most of the SOR-related heavy lifting, so start there if you want to improve how SORs get decoded or want to make something SOR-related that isn't a desktop app.
GPLv3 has been selected specifically to drive improved open source engagement with equipment manufacturers and developers of OTDR processing software in an industry that has struggled with open data exchange, proprietary (and vendor-locked) software, and poor maintenance of existing software.
