🥳Some Updates 🥳
• I've added some more languages as audio tracks by popular demand: French, Ukrainian, Turkish, and Polish
• I've also improved the subtitles script so that should smooth out the dubbed speaking speed, so there should be fewer speed-ups and slow-downs in speaking, let me know what you think.

My favorite internet connector is the “Rio de Janeiro 45” 😂
(Portuguese voice fail)

LTT fans: You underestimate our Lienus

Those are common connectors for me. They are used for every installation for fiber optic internet in Canada and since I worked as phone support for those connections, I have become very familiar with them

Hi Thio. Your YT script for translating and dubbing it on another language is awesome. So many people can enjoy your content even without knowing English. Just a heads up: In my native language (Brazilian Portuguese) "RJ45" are being translated as "Rio de Janeiro 45". I don't know how you can fix this since is an auto translation issue, but it messes with the timing of dubbed lines.

"never look into the end of a fiber cable". THANK YOU for this warning! I have no occasion to walk into datacenters, but this may happen and I could be tempted to do it... now I know! This made my day.

I use these at work all the time :)
As you said, it's frustrating how expensive even regular SFP+ is compared to just straight up RJ45, it's more of a problem for enthusiasts with a use case for them than your average home user.

Finally! A niche computer part I am actually super familiar with!

Years ago i worked in an IT infrastructure renovation project and the guys in networking called them GBIC, but i actually think they were referring to SFP. I had a lot of this things laying around. If i remember correctly we used them to connect a switcher to the fiber optic box and than connect all the floor switches together.

Standard Ethernet cables for the other hosts in the network.

Calling SFP an "internet connector" is beyond words....

[ehsnils]

Anyway - we do have quite a number of those devices at work. Mostly multimode.
The light in the multimode transcievers is actually visible if you use your phone camera, it helps quite a lot when you try to figure out which side that's the dark side.

Home PC devices now come with 2.5/10GPS connections so if you're mating to a switch with SFP+ ports, make sure to check your transceiver specs to see if they support intermediate data rates, most support only 1/10, not 2.5/5.

A couple years ago I bought a QNAP TS-332X Home NAS specifically bc it came with the 10GbE SFP+ port. Added an inexpensive, older generation 10GbE PCIe card to my workstation, and connected to NAS via a copper "TwinAx" cable. Paid $35 for the PCIe card and cable on eBay.

As worked with fiber optics in Telecommunications, just a pro tip. Never look directly into the tip of the fiber cable connected to any equipment (specially industry/corporate grade) . Power ranges of these equipment can be easily in range of above +20 db and that invisible light running through that fiber can burn your fingers let alone fry your eyeballs if looked directly, you can literally see sparks through the plastic tip if touched to a cleaning cloth dipped in alcohol.

They are commonly used between switches in the same network as a load balancer for the switches. Pretty clever idea.

I've never seen this until now, thx for the info!

[stevendamavandi]

What I learned in this video: cool network related sfc thingy, haha funny laser coming out of cable

[LoveHandle]

Well the internet is already a weird, downright strange place anyways.

I'm a network engineer, so this is interesting to see it framed this way. :)

I have 4 Ubiquiti 10 port EdgeSwitches. 2 of the 10 are SFP cages. So, I bought 8 1000BASE-T copper transceivers, because I wanted to be able to use all of the ports if needed. I was surprised at the amount of heat that was coming off of the SFP modules. I read that they can get hot. But geeezzz! I recently bought a Grandstream GWN7803 (28 ports in all) L2 switch, which includes 4 SFP cages. They're nice to have, if you need them.
