Meraki switchs support for 10Gig copper SFP's

[DarrenOC]

Hi All,

I've reviewed the Meraki SFP datasheet and confirmed they don't manufacture a 10Gig copper sfp:

SFP and Stacking Accessories - Cisco Meraki

A project we're working on requires a number of 10Gig copper uplinks for some point-to-point links.  Luckily the switch's we're using have mgig ports so we're able to utilize these. But, for one site we've had to upgrade from an MS355-24 to the 24X2 just to take into consideration this additional 10gig port which is an expensive option.

Has anyone used a Cisco SFP-10G-T-X in a Meraki switch or another vendors SFP? And yes I'm aware that "Meraki won't support this" but if they don't provide a suitable part what choice does the market have?

This has been discussed in multiple topics and the problem has to do with the amount of power an SFP+ port can deliver and the fact that multigig is power hungry.

The vendors simply cannot support multigig SFP+ modules due to the amount of power they require.  It "could" potentially work with an aftermarket module however they can't support it just like you wouldn't support copper network cables over a 100 meters.

Appreciate the response @GIdenJoe, excuse my ignorance and this may make me look like an idiot but what’s the power difference between a copper sfp+ and a fibre sfp+ module?

[GIdenJoe]

The difference is the interface it provides.
A fiber SFP usually has LC fiber connectors (but can have MPO in case of some 40G+ QSFP's).

A copper SFP provides a copper ethernet port.

The insert remains SFP/SFP+.  I think you have some confusion about the lingo 😉

[DarrenOC]

🤣😂🤣😂 I know the difference between copper and fibre sfp types.  I’ll park this conversation under “That was embarrassing”

I used both the Copper SFP+ and the DACs from fs.com.

H @KarstenI , I’ve used fs quite a few times. Cheap and cheerful and does the job. Although unsupported 🫣

I've had a customer plug in a no-name brand 10GbaseT SFP+ they got for something like $30 into an MS350-24X (they had a SAN with 10GBaseT ports that wouldn't work on the MGig ports).

I said I couldn't supply a solution (I'm responsible for it then), but for $30 it was a cheap gamble for them to try.

It's been in for maybe 3 years.  Zero issues.

Your mileage may vary.

I have used the Cisco SFP-10G-T-X and a Ubiquti module as well and had no issues. I am running these in the MS425-32 and MS225-24P
