So I have three DFP-34X-2C2 sticks. Two of them are the old ones (v03) with the external heatsinks glued to them. And the other one is the new one (v06) without the external heatsinks but with some kind of embedded heatsink on it. They both have the same latest 220923 firmware and I used the same ISP foc to check the running temps and Rx power of both and this is what I get:

v03:



v06:



So my questions are:

1. Is this normal with the new version or did I get a defective stick?
2. Why is there a difference in Rx power? I thought that's dictated by the OLT far-end device? For reference, the Rx power reported by my Huawei (ISP-provided) ONT is around -15dBm. So the old version of the SFP stick is close to this value.

Thoughts?

So do I have to ask for a replacement for my new v06 DFP-34X-2C2 because of this issue? Or is the performance even better with this current state?

Do you not have a v06 DFP-34X-2C2 to test with?

Yeah, I have until October 18 to return this. I can just return it and buy another one but it would just be a waste of time if it's the same issue. At least the temps on my v6 is similar to the temps you get on your similar board. What ambient temps do you have when you tested that?

Aside from the upload issue for the v6, any other issues with it?
