I have equipment to do bidi, olts anything someone may want.
Power meter is the only way to really know your span loss.
With my better splicers we can see the quality of the cleave and the fiber
itself.
None of the splicers measure the loss anymore, they use some kind of graphic
image algorithm.
I like my splices to all be .02 or better. For example, my first customer
RX optical level is 17 dBm this morning. Leaving the C.O. splitter it is
17.0 And they are 8000' away. Nice to see. Hard to believe. That is what
the 844G is reporting.

Re: fusion splice losses, is the first the loss reported by the fusion
splicer and the latter a measured value?
Do you measure with light source and power meter or bidirectional OTDR? One
way OTDR shots are only an estimate and may report incorrect loss values for
splices.
Even at 0.1 dB fusion splicing is far superior than mechanical splices that
average 0.2 dB - 0.75 dB.

I have found that the db loss on fusion splices to be wildly optimistic.
It
may say .02 dB but in reality be .1
They just guess at it based on the look of the fiber. The old first
generation splicers actually injected a signal and read the splice loss.

Just as an FYI, there are some nonexpensive fusion splicers out there.
Chinese models (AI-8/AI-9) for under a grand on Amazon. Less on
eBay/Aliexpress. I got one. It works. There's apparently an add-on for
splice on connectors.
Smaller handheld models from Jilong (a grand) and Easysplicer (bit over a
grand, V groove, Swedish manufacturer). Both support splice on connectors.
FOA mini "review" on the Easysplicer:

Any of those should work for terminating drops. Personally I prefer fusion
splicing over mechanical splices.
