RE:50G PAM4 Upgrade = TAC (Tencent Active Cable)
They even say that ACC is LESS expensive that DAC (Passive) when all is said and done!
Wow, forst time I've hear that!
Great article
"ACC must be cheaper than DAC. Under 50G PAM4, taking 200G 1 divided 2 copper cable as an example, 2.5m is the intersection of this cost change, exceeding 2.5 m copper cable applications, using ACC not only has a larger performance margin, but also a lower overall cost ."
