Re: [AFMUG] PLC SplittersUnless you are in high density subdivisions like I am, 
I would go with splitters in the splice case.  Saves a ton of money.  But you 
have to be committed to PON.  In our method, we can make any sub active with 
just opening the cabinet and moving a jumper.

Direct splice versus cabinets and patch panels: 

Direct splice is less expensive, reduces vulnerability to vehicle/plow damage, 
easy to test the drop cable, and only a single location needs to be visited to 
turn up a customer.

Cons are increased difficulty in troubleshooting and potentially reflection 
from unterminated cable (though I have not seen issues and several other have 
reported no issues).

  Now that I think of it, all of our splitters are in cross boxes with them 
appearing on patch panels in the neighborhoods.  We insert a patch between the 
splitter output to the strand going to the house during install time.  Each 
strand to the homes have their own place on the patch panel too.  

  So, all of our splitter outputs are unterminated unless they are in use.

  We must have over 100 splitters installed that way.  I would say we only 
average about 20 users on a 1x32.  We haven't seen any issues either.

       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.

              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

                                I'm looking to possibly do a trial GPON 
deployment on a leg of my active network, it looks like the 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?
