@mattcen I would be shocked if Opticomm let you do this. Also, it's highly likely the OLT at the other end of the fibre is Huawei, as well as who knows how much of the rest of their network.
As long as you're using secure protocols I wouldn't worry any more about that NTU than I would about any of the equipment between you and the destination network, made and owned by god knows who 🤷♀️
