I'm trying to learn about OM3's current limits if I just want two, one for send and one for receive.  Other stuff I can find talks about bunching 12 or whatever together.

10gbit @ 300M currently.

100gbit @ 100M supposedly when it becomes standard.

And that 100 Gbit is with a single pair?  I'm curious about this.

Its currently being done with multiple fibers bonded together. Those specs list 100gbit using MPO @ 300M. But the future specs I've seen for OM3 @ 100gbit don't list any caveats like MPO being required.

The next iteration of ethernet will be 40gbit before they work on 100gbit. I guess that 10x leap was just too much. I'm sure they've done the math and proven mathematically the fiber can support that speed in theory.

Kind of reminds me of 4mbit, 10mbit, and 16mbit token ring.

That pretty much settles what I'm running in this house when the Cat-6A either goes bad or becomes obsolete.

Why not just run GPON through your house if you're going to go that far?

I figure 10g is going to be enough for quite some time. I don't see people really utilizing 1g as is. Copper termination is cheap and simplistic compared to fiber.

He should just get a 25Tbps router stack now, you know for when his copper is obsolete.

I have seen 400G for a single pair as a standard. I think that was for 10M length.

They're doing that on OM4 not OM3.

Do any of these future specs have names?

Could put in single mode fiber to be sure

144-strand ribonized to every wall jack!  It's the only way to be sure.

So it's IETF.  That's a start.

So, what do you do that you think you're going to need 100Gbps LAN?

Plan for the future.

Still, though, this Cat-6A has 19 years of life left.

How do you know that the future of LAN is in fiber? How do you know that it's going to be OM3 and not OM4 or some other strand spec that doesn't exist yet?

Point is, if you want "future proof" then you're better off installing conduit to make replacing facilities easier than trying to install some projected future used facilities.

Same here.  I am running fiber to my shop but that is just because it is a good idea due to potential grounding and lightning issues.  Cat6A is more than adequate for home use.  In reality Cat5E is supposed to be fine for 10Gb up to 30 meters.

There is really no reason to run fiber in the home for 10Gb in my opinion.  I am running 1Gb right now and even moving 16TB's of data over the last few months for Plex it was plenty fast.

You know, you guys are right.  This is stupid.  I've currently got 10 Gbps ability with twisted pair and that will do.

I am all for doing things for fun but I think you are wise to stay with 10Gb for now.

Actually, I'm still on gigabit.  I just put Cat-6A STP in so that in ten years, I could just drop a 10G switch in and call it good.

That works too.

I am only using Cat5E at my house right now as I intend to test the 30m limit of it with 10Gbe at some point.

I am going to dig the trench for my fiber run to the shop on Sunday and hope to have it up and running by the weekend after that.

I have been running CAT6A through the house in anticipation of upgrading to 10G.

10G RJ45 NICs are coming sown in price ($100 for dual port 10G intels) but 10G RJ45 switches are still expensive and buggy for ones less than $1K

SPF+ switches are a lot cheaper and SPF+ NICS are really cheap used on ebay.

I am thinking of buying a mikrotik 24 port rj45 gig switch + 2x SPF+ switch ($120 Mikrotik CSS326 Switch) and using 10G fiber to connect my server and my workstation to the rest of my 1G network

Most drives today will easily saturate a 1G network link. Some NVME drives can saturate a 10G link.
