We keep going on about 5G networks, but there's so much Huawei in fibre access networks i.e. FTTC (VDSL) and FTTH in the UK, Ireland and many other countries.
You'd just wonder what your traffic is passing through. I'd have doubts that most of the telcos really know what they have in their network other than they're plugging together increasingly complicated 'black boxes' and most of them outsource almost everything to the vendors anyway and have little or no serious skills in-house anymore.
Often entire networks are being delivered as 'turn key' projects.
