Moving Calix ONU box into garage

So I decided to move my Calix ONU into the garage. I installed two sections of this Singlemode SC/APC cable and joined them with this adapter.

I tested one section before installation, and it worked fine with the Calix ONU.

Unfortunately, once I moved the ONU into the garage, the broadband light no longer comes on, likely due to high attenuation.

I also have OM3 multimode cable running alongside the two sections of singlemode cable, and it works fine for LAN traffic, so I don’t think the environment is causing the issue.

I suspect that the installed CitiFibre cable’s LC connector has high attenuation because it was covered in a lot of brick dust. Additionally, the entire brown fiber box installation was poorly done, with misaligned holes, overtightened screws, and a heavily bent white fiber cable that I had to replace for troubleshooting.

I tried moving the ONU between the first and second sections of the fiber cable, but it didn’t work there either, despite the initial test being successful.

I checked both sections with a fault locator, and there were no issues detected.

Any suggestions on what can be done next? Is there a way to monitor the Rx/Tx signal strength from the Calix ONU?

Have you got a fibre cleaner?

I’ve got mine extended using MM OM3 and it’s fine.

Does your router allow you the rx and tx strength

Oh and if the fibre was bent, that’s not going to help and maybe the glass broken or fractured inside

Have you got a fibre cleaner?

Yeah, I cleaned all ends and still no luck. I guess I am stuck with current setup for now.

Does your router allow you the rx and tx strength

Yes but I am more interested in signal strength for ONU.

Oh and if the fibre was bent, that’s not going to help and maybe the glass broken or fractured inside

I replaced bent section with this cable.
