So far, I have not encountered a problem caused by unterminated lines. I think
it is due to the fact that it is frequency division duplex and the transmit
reflections not only have to experience splitter loss on the return trip but
there are no receivers looking for energy in that direction.

I have use the ‘bare’ FS PLC splitters before. I can’t recall if the pigtails
had color or were just numbered but they are coated and strip off exactly the
same as the regular 250um acrylic coating. For what it’s worth they fit
nicely into a Tyco A or B size splice tray. we direct spliced one into a case
and terminated all 32 outputs onto the distribution cable.
I don’t know that I would do that again simple because it creates a lot of
drops with no control over the reflection at the far end until you connect
those strands to customer houses or another termination panel. So far it has
not created any operation issues but to some extent I think we just got lucky.

When you strip it, it sure looks bare. All the color is gone.
After you strip it, you wipe it off with an alcohol wipe.
And then when you see it in the fusion splicer screen, it looks bare there
too.
Actually it probably has to be totally bare or the coating would contaminate
the burn.

If the glass was truly "bare" it would be 125um and also be too fragile to
handle. What is referred to as "bare fiber" actually has the 250um acrylic
coating, probably with color added. It's the barest the fiber can be while
still being workable.

That must be it, the "bare fiber" description is a bit misleading in that
case though. Strange way to specify the diameter.

That sounds strange to me.
Is there such a thing as PON on multi mode fiber?

I'm looking to possibly do a trial GPON deployment on a leg of my
active network, it looks like the FS.com PLC Splitters are 250µm. However,
singlemode fiber is usually spec'd at a cladding of 125µm. Are they just using
a different measurement or some sort of oddly sized fiber?
