Canada at it one time got it own telco equipment called Nortel, but thanks to the management that prioritize stock price over R&D, the end fate is not hard to predict. i know bell and telus are big players. my guess is smaller players tend to use Huawei & ZTE as they don't have the big barjet like their big player counterparts, as they are serving rural area where less revenue can be generated. as in the case of USA. Federal Government have to subsidize the replacement cost, which is cut the nose to spike the face. Which ever that float the boat of these unhinged governments.
Transceiver? that mean you are on FTTH?

UM going to surpass many Telcos in 5G network
Celcomdigi Maxis loyal users stuck with rubbish 5G by DNB
Better Govt drop DNB let telcos build and activate their own 5G. 5G really worst in covered places

Point of reference? Which telco? Device used?
