Make sure the Ethernet suppressor is grounded so it can shunt both common mode and differential surges. You most likely do not need to even power on the UPS with the coax, just plug it in so it has ground, and it'll work as a surge suppressor, this way you can continue to use the current one...

It may be difficult to get the UV to the area between the ferrule and fiber. Either a 5 minute two part epoxy or the old school method using anaerobic glue might be cheapest to try. Anaerobic glue for fiber is a very close relative to locktite/threadlocker. They cure in the absence of oxygen...

Since you mentioned the first device was a switch and now a firewall - both networking - I suspect the coax/telephone lines are the source. Assuming it's not fiber. What's connecting you to the ISP? I would get a gas discharge tube (gdt) + TVS diode Ethernet surge suppressor, two cheap media...

Yes, I have used these, bought some to just see how they performed. They worked fairly well, though I didn't test with my OTDR, IIRC, the loss was about 0.5-1 dB with decent cleaves. You can use a VFL, you just have to look straight down into the top (the side you press in). The ones I got had a...

You know, it should be pretty easy to modify a cheap amazon/ebay 4 to 1 hdmi switch to be controlled from a raspberry pi (or similar SBC) GPIO. That would let you change inputs remotely. If you could duplicate the output of the switch, and feed one to the tv, one to one of those $8 usb hdmi...

Found the command here, fohdeesha strikes again! My switch should arrive in a week. I'll update with results of whether my optics play nice

Long time lurker, first I want to say a massive thanks to @fohdeesha for taking the time to post that huge thread. It is a great resource, and was the exact reason I chose a brocade for my next switch. I bought a 7250 yesterday, and I already have some FS and other 10g optics, which from what I...
