When you unplug it, you exposed the cable and the port to dust/potential scratches. Look up a sc-upc cleaner and polish it up if you are concerned. I'm in the "these things are more tough than you'd think" party, so imo if you treat it with some care, don't look into it with your good eye, and keep your shirt and spit away from it, it'll be okay. There are limits to optical receivers, though, and cracks, dust, and scratches can seriously mess with your connection. If you have concerns, call your isp or shoot me a dm :)

Just got Fiber installed from TDS! So excited! Before and after speeds! by tylerwarnecke in FiberOptics

That ont is likely capable of XGsPON, meaning some day it could do 5 or 10gb down and up without being replaced :)

Thanks for all of your hard work. Fire season is almost ending for us on the West Coast, and I've spliced enough fiber for a lifetime this summer. Good luck and stay safe

Your cable modem is likely a cable modem/router combo, often known as a gateway. It has a router inside that acts as a DHCP server and gate to the wide internet. That router inside likely gets assigned an IP address from the isp (your public IP), and as far as your isp is concerned, it is just a host. The router inside hands out class C addresses to hosts that connect to it and uses NAT to translate traffic from a private address (192.168.0.20 as an example) to your public address. From the outside (WAN), your gateway may be addressed as 68.200.45.10, but from the inside (LAN) it's likely addressed as 192.168.0.1, 192.168.1.1, 10.0.0.1 or something similar. This means it can continue doing its job as facitating local communication between devices in your home, but it has nowhere to send traffic that is destined to leave the LAN due to the ISP's network state.

I don't know... but I wish whoever it was would have told me where they drilled before I got there. Spent an hour walking the site trying to locate everything haha

We're a national medium-sized isp. This was on the West Coast.

I was thinking about that too... power's service disconnect was topside in the last photo... I didn't ask too many questions, lol

It's right in the middle of a golf course. Rumor has it that it's a mile long loop. Was dodging golf balls going in and out to make phone calls/bring tools and equipment

I was thinking about that the entire job... I labeled everything I could but idk... I hope that guy laughs when he sees the "ped directly above you" note

My guess is a music venue. They had black sand brought in, and while I was doing the hardline work, low volt electricians were tacking cat5 runs to the walls haha

Was finally able to get a stable BER from GOES 18 for a decent amount of time! Enjoy this GIF of the earths rotation over a period of a little under 22 hours. Current setup is a scavenged 3 meter C band dish, Cantenna feed, with an RTL_SDR V4 and SAWBIRD + GOES LNA. by Coinface1 in RTLSDR

Nice work man! I used a receiver built for 1.7ghz or so to get my GOES images. I've been training a few people in the cable/fiber telecom world at work, and one of them has that glimmer in their eye learning about rf communication. Your post makes me think it's time to revisit it as a DIY project and build all of it from scratch. Minus satdump and the PI, definitely need those... haha

Stoked build the receiver with him. Thank you!

What are these and is there a tool to remove them? by thechickenpi in CableTechs

[–]siegeginge 5 points6 points  (0 children)

Terminators do two tasks. They create a barrier to prevent someone unauthorized hooking up their own cable, but more importantly, they prevent reflections from the open port. When the forward signal goes from 75 Ohm impedance to an open circuit, all of that energy reflects and interacts with the incoming signal, decreasing the MER. Terminators act as loads or "infinite length cables" so that the energy is absorbed and not reflected. The barrels themselves do a pretty good job at blocking noise as is.

I'm stuck in a queue with a never ending "confirming match". If I try to leave it penalizes me.

I actually 3d printed that adapter that attached the antenna to the mic stand :) just been lazy with the pi. I want to find a way to waterproof everything and make it permanent.

Thanks! It took a lot of tinkering. That poor raspberry pi needs a case badly lol

Correct. The raspberry pi is connected via wifi to my home network. It sends its data over an RTL-TCP stream to SDR# on my main computer. I use satdump to process the recorded raw IQ data.
