SFP-10G-LR-S vs SFP-10G-LR

Ciao,

is there anyone that can explain what is (are) the difference(s) between the two optics in the title ?

In particular what are the "unnecessary features" of the SFP-10G-LR-S ? Can they be used in UA to Core deployment ?

BR,

Luciano

The table below shows the key feature differences for the 10 Gbps S-class vs. C-class.

For UA to core campus applications, S-class are quite suitable.

 

C-Class

S-Class

Multi-rate vs Single-rate

Multi-rate optics:

  • Ethernet
  • OTN
  • WAN-PHY

Single-rate optics:

  • Ethernet only

Operating temperature range

  • Commercial (0C to 70C)
  • Extended (-5C to 85C)
  • Industrial (-40C to 85C)
  • Commercial (0C to 70C) only

Dear Marvin,

thanks for you kindly replay.

May I ask you where did you find the above table ?

You're welcome.

It is from an FAQ developed internally at Cisco and provided to the partner community to assist in product presales positioning.

If it answers your question, please mark as such. Thanks.

Hi Team,

Can anyone support if N3548 support 10G classic transceivers (SFP-10G-LR-S=)?

They are not listed as supported in the compatibility matrix.

Please note that the S Class SFP's doesn't support FCoE.

how do you tell when looking at the part number if it is S class or C class or can you even do that. If not where is the class specified per part number in the data sheet?

S class transceivers have "-S" at the end of the SKU (Stock Keeping Unit, also known as part number).

SFP-10G-SR = most common non-S-class 10 Gbps transceiver

SFP-10G-SR-S = S-class version of the same

I was wondering the same thing. I'm looking for SFP+ modules to go from core to building distribution switches, and the cost of migrating from 10G X2 modules to SFP+ is insane!!

The Cisco S-class optics is compatible with non s-class optics, except that S-class optics has different temperature ranges. 

And if you want to replace the X2 module with original SFP+ module, the total cost is high, but you can find a OEM vendor to help you out. I have bought compatible Cisco SFP+ modules from Fiberstore for just $16. You can have a try !
