10 gigabit finally coming down in price!!!!

i think the next step is 50gb, then 100... they say 50 might or might not be prominent, depending on how things go... but after 100mb we probably wont be seeing copper wires. really i doubt anything over 50gb will be feasible on copper.

40G is the jump. and there is 100GBASE-CR10 for copper 100G

common terms can be found in:

lolz.. so basically 10gbs is the limit for copper... twisted pair anyway. above that its banded. I remember from school, coax can support around 100gbs, but after that they will need to use fiber.

Similar to 40 GbE, 100 GbE uses electrical lanes of 10 Gbps with scRambled encoding to create 100 Gbps
links. 100GBASE-CR10 supports links up to 7 meters over 10 pairs of Copper wires in each direction in a
jumper cable assembly.

does that say 40 conductors at a max of 21ft?
 
I wouldn't put one of those NetGear switches in my business if you paid me to. If you need that many 10gbe ports, you can afford a Nexus 5k for them.

In regards to speeds, these Ethernet speeds follow the SONET standards. OC192 is four OC48s, and each OC48 is roughly 2.5gbps...thus OC192 is roughly 10gbps...so 10GbE uses 4x 2.5gbps channels to get 10gbps.

40gbps works the same...OC768 is 4x OC192...you get the idea.

They're two different PHY standards. LAN PHY 10GbE has nothing to do with SONET and its encoding/multiplexing should not be confused how the WAN PHY standard works. While it's similar in the fact that it is channelized, it's not SONET.

Thanks for not reading what I said.
 
I could see 10Gb being used on the servers, but it'll be many, many years before we see it on any client machines, if ever.

That's what they said about 100 Base-T
Same as was said about 1000 Base-T
And it will be said about 10G Base-T until it's common place everywhere.

10 gig has been rapidly dropping in price for about 4 years now.

You said they follow the SONET standard at those speeds. They do not. You're mixing terminology.

I didn't say they WERE SONET. I said they follow the same progression.

If you don't believe me that 10gbe implementations are based on 4x 2.5gbps channels and that 40gbe is based on 4x 10gbe channels, you need to do a bit more reading before we converse any further.

nothing is fast enough for the amount of porn and spam email we generate on a daily basis. i wonder how many carbons those two things alone put in the air?
 
I just picked up a Xenpak 10G-LX4 optics module off ebay for about $10. My brother used to work at a reseller, and tells me that he used to sell these for several $k.

I've got no use for it, I just want to take it apart and see what's inside.

They went for 4k-10k if I recall depending on what Xenpak and fiber you were using.

Today 10 gig is on a SFP or a Twin-AX cable with SFPs integrated into the cable assemble. You can get the twin-ax cables for a few hundred bucks, much cheaper than the optics.
 
people overlook infiniband, in a lot of use cases (especially storage) it's much more cost effective. I build a virtualisation cluster a couple of months and went 20Gbit infiniband for a fraction of the cost of 10 Gbit ethernet

Yeah but to be honest, most of my users wouldnt notice falling back to 10mb, very few would notice dropping to 100mb and 1gbps is hugely overkill for everything we do other than OS and software remote deployments. We are getting to the point of diminishing returns.

Im sure in 5-10 years we will start to see 10gbps to the desktop, but its going to be overkill for all but the most hardcore users. Video professionals and researchers and programmers might need it, but the average office worker could go back to 10mb without a care in the world.

That's also what was said about 100 and 1000.

And for the most part its true, the price difference just got to the point where it really didnt save any money to go slower.

I stand by my claim that the vast majority of users would be perfectly fine on 100mb still today and a large portion would be ok on 10mb.

I don't know if I agree with that. I work in a fairly small environment (less than 100 users), and people that are not very tech-savvy are starting to have a lot of expectations about the speed of their network connections. I've had more than a few people complain about how long it takes to save large files to shared folders or network drives, and our environment is gigabit to the desktop. When I questioned them about how long it takes to save, they said "well it may take 5 seconds to save to the server, but saving to my local desktop is basically instant". It's obvious to me, and to most of our executive-level staff, that a 5 second delay is completely acceptable and does nothing to slow down the actual productivity of someone. But, it's very telling that end-users are starting to notice this type of delay and are not always accepting of it.

Just in case anyone is interested. Here's a pic of the optical multiplexer from my LX4-Xenpak:

That sort of optical assembly can't be at all cheap.
