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

[Manu MP]

Hi,

What is the mail difference between SFP-10G-LR-S and  SFP-10G-LR. I have tried to collect information from datasheet and other forums. But no details got.

C and S Class :

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

good compare here from FS- same applies most of the SFP.

Hi Manu,

The main difference between the two Cisco SFPs is that SFP-10G-LR supports FCoE, whereas SFP-10G-LR-S does not support FCoE.
This is why the variant 10G-LR and 10G-LR-S have a slight difference in prices.

Which means that if you have an interconnectivity between the two distant sites and you need to pass the FCoE traffic, you must consider SFP-10G-LR. 

This will also be helpful for you in planning the relevant BoQ.
