SFP recommendation for C9300 and CBS350

[Edward S]

Hello All,

I'm new to Cisco community and I want to apologize if my question has been answered.

We have bought a Catalyst 9300-48 network switch. The retailer has advised to buy GLC-SX-MMD SFP modules for it. The rest of the network will be based on CBS350 switches.

I've spent a lot of time looking on tmgmatrix.cisco.com to find the SFP module for CBS350, which would work with GLC-SX-MMD, but it's a bit confusing.

Can you please advise?

Regards

Edward

Hi

 Which exactly CBS350 do you have?

[Edward S]

CBS350-16P-2G, CBS350-24P-4G and CBS350-24T-4G

On the switch datasheet, the GLC-SX-MMD is listed as supported:

Supported SFP modules	SKU	Media			Speed			Maximum Distance
	MGBSX1	Multimode fiber			1000 Mbps			500 m
	MGBLX1	Single-mode fiber			1000 Mbps			10 km
	MGBLH1	Single-mode fiber			1000 Mbps			40 km
	MGBT1	UTP cat 5e			1000 Mbps			100 m
	GLC-SX-MMD	Multimode fiber			1000 Mbps			550 m

OK so GLC-SX-MMD is for C9300.

Will the CBS350 support it too? If not, then which SFP module should I buy to pair with GLC-SX-MMD on the other end of fibre cable?

Thank you for helping me.

I did test the connection between C9300-48P-A and CBS350-8P-E-2G with GLC-SX-MMD modules, LC-LC Duplex MM cable and it works like a charm. Thank you all for your help.
