Sfp/+ how hot can these get ?

[Syko]

I have a switch which has two unused 10g SFP ports ,

i would like to start and use them but only for say running a ethernet cable to tv that barely get used and for a PC that is mainly used for light browsing again doesn't get much use ...

so seen as there not going to get much use , how hot will these run when their are in use ?

max speed running through the ports would be 1gb

Hi @Syko - Should not be that hot. I regularly worked with SFP (like) connections in HPC clusters using Infiniband (400GB interconnects) and when that line gets saturated they can get REALLY hot. So, unless there is some chassis/OEM issue that might bugger them, a 1GB throughput shouldn't be an issue but I'd love to hear your experiences!

Thanks 

I ordered a sfp+ last night should be coming today , 

So will test it out,  

Like Normal basics web browsing and YouTube,  and file transfers of a  max speed of 2.5gb 

But it will mostly be for web browsing.

just for home use so nothing fancy at all lol

Sfp+ came today , tried it and it started to fail very quickly,  transferring a few movie data files from one place to an other about 3tb worth of data and it dropped from 256MBps  to just 50MBps in a short time,  tried a few ways but was getting the same result,  so this is getting returned unfortunately..

Odd. Maybe you got a bad one...they do fail more frequently than NIC's and Ethernet cabling. If you ever want to test your throughput Iperf3 is a production grade tool.

Decided to go with big switch ( more ports ) 

With  the cost of two sfp+'s. for a few quid more I can have a lot more ports 

At the moment I would using all the ports up that's available. 

Every now and again I'm building a pc and upgrading laptops,  so with the extra ports on the switch it will save me from unplugged other devices. 

1st world problems lol
