Nah that’s no good Carl. Your bias current is [censored]. You need to turn that sucker waaaay up 🤣

1.21 Jiggawatts!

In all seriousness the received power level is stronger than I would have expected. Minimum 16.5dB loss from a 32-way split... I think the Huawei OLT has a max TX of +7, so not a huge amount left.

The OLT reports its transmit power. I'll have a look when I'm back.

Depends on the class of optics in the OLT. They could be using a higher class than the ONT.

I think my line was -21dB when tested, they tried another port an it was worse, wasnt sure if thats good or bad, but ive had no issues since it going in

From what I can see Openreach are using the Huawei MA5800-X17, on a brief search all the line cards I found were designed for C+ optics which max at +7dBm. That's not to say they don't have a C++ option.

That's more like what I'd expect, C+ sensitivity is (I think) -32 so you should have no issues.

Not sure what you mean. Rx power is -13.07 dBm and has a minimum of -30 dBm, so there is *tons* of headroom. Tx power is bang within the middle of expected range too.

I'm not at all concerned that it won't work - I'm actually surprised that the signal is so strong. I'd be very happy to see such a signal level when I get OR FTTP.

There is a minimum loss of 16.5dB due to the 32-way splitter, so if the OLT is transmitting at 5dBm that only allows 1.5dB for all the splices, connectors, and loss in the length of fibre itself.
