Should I Upgrade My Network to 25G or 40G?

Hello everyone,

I’m planning to upgrade my 10G network. I know that 25G is very popular at the moment, but 10G and 40G have been active on the market for a long time. If I want to upgrade my 10G network, should I upgrade to 25G or 40G?

1.There are many 10G and 40G compatible products on the market. If I upgrade my network to 40G, the solution and matching products should be found soon. If I upgrade my network to 25G, will there be a shortage of solution and compatible products?

2.40G products seem to be cheaper than 25G, I have to consider the budget.

3.Power consumption and heat dissipation are also my consideration. Will 25G products perform better than 40G?

1. However, the upgrade route 10G-25G-100G seems to be better than 10G-40G-100G. And this solution is also good for the later 200G, 400G upgrade.

Anyway, I have not made up my mind, so if anyone has any good information or suggestion, please tell me. I appreciate that.
