What is the expected growth rate for the Avalanche photodetectors inside of GPON equipment in 2022
arting to sort of come back to normal. And so that risk has come down dramatically.

Okay. Great. Thanks. And then maybe some base station deployments in China. It seems like they've been a little bit slower roll out and COVID pockets are starting to appear. Just kind of curious your thinking about the base station deployments and just generally overall, kind of the China, Mainland, how you see that performing over the next maybe 12 months?
Stephen G. Daly -- President and Chief Executive Officer and Director
So I think there's going to be steady, very moderate growth. That's our expectation. There's been a lot of tenders out earlier in the year, mostly for 700 megahertz. We have little exposure to that platform. So from our point of view, deployment in China will be very muted, I would say, based on our current outlook. And from our point of view, what's important is that we win market share when we get our newest products, including our gain on silicon carbide, massive MIMO power amplifiers designed in wherever we can, and that's the focus for the business. We are seeing also an uptick in interest with ORAN. We're seeing an increased interest from international companies outside of China that are interested in MACOM's products, not only on the RF side, but also on the optical side as well as on the PON side of Telecom networks. So while China might be a bit muted, we see other opportunities outside of China.

Hi guys. Thanks for taking my question. I wanted to go back to Telecom and ask about growth drivers for the next year. I think at the beginning of the call, you listed out four things, if I remember right, as growth drivers there, including PON, cable infrastructure, microwave radios and SATCOM. And I was curious if you guys could just kind of rank order those, how you think those will impact your telecom growth in F 2022? And then if you could kind of comment on how you see potential cable capex spending rollover, balance out between kind of a lot of the new initiatives for fiber and fiber-to-the-home that have been going out here in the last couple of months? Thanks.
Stephen G. Daly -- President and Chief Executive Officer and Director
Thank you. So it's very difficult for us to rank order in those end markets. I think they're going to grow at different rates at different times during the next 12 months. We think that, as I talked about at a high level, our expectation is 15% year-over-year growth for the entire segment. Certainly, 5G will contribute, no doubt. Cable infrastructure is very strong right now here in the U.S., we do expect that to continue. To your question about sort of capex spending. We think this is a multiyear cycle. This will not be a 12-month cycle. This is a three year cycle minimum. We also believe that we're winning market share in 10G PON, specifically on burst mode TIAs and drivers, where we have a very strong position and lasers. So the 10G PON market will be an area where we have very strong growth. We also, I'll just point out -- and again, this speaks to the -- our thesis that our growth is product driven. We are gaining traction with our Avalanche photodetectors inside of GPON equipment. And so that's also exciting for us. So really, as we think about Telecom, it's our core product lines getting stronger and winning market share, whether it's high-power switches, front-end modules for base stations, components for fronthaul and GPON. So a lot of moving parts. I wouldn't necessarily want to rank order any one of them as being more important than the other.
Sam Peterman -- Craig-Hallum Capital -- Analyst
Got it. Okay. Thanks for all the color there. And then just a quick follow-up on capex. It looks like a pretty big step up to -- from $20 million-ish in the last two years to over $35 million this next year. You said it was mostly around production capacity in your fabs. Is this kind of rampi
