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.

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).

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.

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. From: Mark Radabaugh Sent: Friday, August 11, 2017 7:21 AM To: af@afmug.com Subject: Re: [AFMUG] PLC Splitters 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.

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.

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. ------ Original Message ------ From: "Jason McKemie" <j.mcke...@veloxinetbroadband.com> To: "af@afmug.com" <af@afmug.com> Sent: 8/10/2017 6:24:08 PM Subject: Re: [AFMUG] PLC Splitters That must be it, the "bare fiber" description is a bit misleading in that case though.

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? -Jason
