Question Need a MoCA PoE filter and other interference questions

Hi all, thank you in advance for your help! I have some questions about the need to address any possible interference on my cable line.

I have Xfinity 2100/300 MB service with a Netgear CM3000 modem. The modem signals/error levels are good, but I do experience some T3 errors, not a lot, so periodically and I inspect connectors, cables etc. looking for any issues. I have no splitters, the cable runs from the outside box directly to my modem.

I live in a row house in an urban setting; the houses are very close together. The cable comes in from above lines.

I have included a link to a picture of the cable box outside

As I look at this picture, I see 1 line (circled in red) that is a dead line not being used - which makes sense; at my address Comcast lists three “accounts”, only 1 being active (mine) - they call them Apt 1, Apt 2, Apt 3 as years ago my row house was 3 apartments before the former owner bought the building and completely renovated it to a single home. So there is at least 1 dead cable line.

My questions are these:

1) I see no MoCA PoE filter unless I don’t recognize it. Given the density of the area, should I get one? As I said the cable runs from here right to my CM3000, which has no PoE filter from what I read? I wonder about this as the cable line was installed well before DOCSIS 3.1, mid-split, etc.

2) If I need a PoE filter, which one do you recommend I buy, and where do I place it - in this box somewhere, in front of my modem, or elsewhere?

3) Below this box, there is a Verizon phone box - it is not used; there is no Verizon phone service in the house. The former owner had land line(s). I assume the wires in that box won’t generate any interference (I can supply a picture of its insides if needed)?

4) Does the ‘dead’ Comcast cable need to be addressed, or ‘capped’ in any way? Could its cause some interference as it shows right now? There is no active service on that cable but I don’t know if it emits or could be the source of interference.

Thank you again for your help with my questions!

Why would you believe there is PoE on your incoming cable? EVERYTHING in this box is not your responsibility. It is the cable company's. Your responsibility starts after the grounding block.

Sorry, I don't think I said I believed there was a PoE in my cable. That was not one of my questions.

What leads you to think you need a "PoE filter"?

The title of your post is "Need a MoCA PoE filter" . So if you don't believe there is power on your coax, why would you believe you need a PoE filter ?

Also....
"PoE" can have different meanings.

Power Over Ethernet (which is what I thought)

It sounds like the OP spoke to someone - either they work in AV or for a cable company - and started to do research online about Satellite services like DTV needing a MoCA POE and confused it with cable. The fact he knows signal information leads me to think his new job is with a cable company... and then deleted it all...

Since the OP deleted their original post. This thread is done.

In light of the OP "deleting" his original text...closing this.
