Real OzBargain'ers buy first and ask questions later :)
If you don't know then you more than likely don't need it but it plugs into a switch port to provide a connection for a LC fibre cable.
Extreme Gamer Network Equipment.
Now that we have 1Gbps on alternative NBN fibre and 4G/LTE and over 100Mbps from Wireless ISPs, we need 10Gb parts like this to make sure home/business networks have the headroom to handle multiple Gigabit traffic from outside and inside.
That's not really the use case. Think large company with multiple switches. The uplink between the two switches may require 10Gb bandwidth to cater for all the users and usage.
I've only ever seen these used for large business networks backbone infrastructure, however, I'm not a heavy gamer.
@try2bhelpful: Jokes aside, I think some gamers would be interested in learning about this stuff in the pursuit of higher performance, even if it's completely wrong or overkill for their needs right now.
Some large households have requirements higher than others too, so a 10Gb link between floors or ends of a house might not be such a crazy idea.
And does it take eneloops
fibre optic transceiver …. it's on the NAPLAN syllabus as we train our kids for the jobs of the future.
3.0KGs!!!
3.0KGs!!!
Actually, the SFP+ is only .3 Kgs but the packing material is about 2.7 Kgs.
Excellent way to get 10Gbps speed between compatible equipment at home.

Or get a compatible one here: https://www.fs.com/c/generic-10g-sfp-plus-1413 for AU$20 (plus shipping)
(FS stuff is excellent)
That's where I buy optics from 👍
Yeah - I just found them a few days ago for some SPF+ cables! Cheap!
Wow…things that you can find on ozb…
…Each…? o.O
Just what I need to then be bottlenecked by my FTTN NBN
Get all your neighbours to buy one* as well, setup a window2window LAN then aggregate all those pathetic FTTN links into a single just-barely-acceptable-anywhere-else-in-the-world link!
You'd only need 400 houses @ 25Mbit/house to get 10Gbit :D
(* plus all the other stuff they'll need, totally ignoring all the infeasible aspects of such a system)
You’d think so but typically FTTN backhaul is 1Gb not 10Gb
Off topic but they use dual links (for redundancy I assume?) and most are currently running at gigabit speeds (so 2Gbit per node). Typically nodes have well under 100 customers so absolute worst case it's a 5:1 ratio. In reality it's closer to 2:1 (considering average of ~40mbps connection speed). NBN has the capability to upgrade this to 10Gbit in the future, though hasn't got the need at this stage.
For reference, customer connection speed to CVC (long distance backhaul) ratios are around 25:1 - 50:1, depending on provider.
Checked design specs and by design all nodes have 4 point to point fibre links, with 2 in service at 1gbps.
Nodes can apparently service up to 384 customers, so around 5mbps per customer. Realistically at current times average speed tier is ~35mbps (though on the rise), so a current ratio of 1:7 for backhaul. The customer speed tier to CVC ratio of 25:1 - 50:1 is correct. For example, only 2 - 4Mbps CVC would be purchased for a 100mbps connection. This is slowly on the rise with the announcement of the new wholesale pricing.
So uh.. what is it?
