S-Class SFP+ compatible with "normal" SFP+ ?

[Carlos Velasco Cebrian]

Hi,

Our provider has sold us some new "S-Class" SFP+ LR transceivers. Part Number: SFP-10G-LR-S=

http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/bulletin-c25-733742.html

http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/datasheet-c78-733585.html

But we need to connect these SFPs with "normal" X2 LR transceivers. Part Number: X2-10GB-LR=

Anyone have expererience or knows if "S-Class" transceivers are fully compatible with "normal" transceivers?

Reading Cisco documentation does not say anything about this.

These just came out in December so I haven't seen anyone deploy them yet nor had a chance to get any hands-on myself.

The data sheet says they are "10GBASE-LR 1310nm SMF" which matches the standard of your X2-10GB-LR= transceivers, so they should work fine.

Let us know if you find out any different.

UPDATE: I've received internal verification from Cisco (2 sources) that they are compatible.

Hi Team,

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

Regards,

SFP-10G-LR-S=  was launched in December last year so they are pretty new and the specifications are same . Apart from that , unfortunately there is no difference document yet for this.

SFP-10G-LR-S=

Features and Benefits

Main features of Cisco 10GBASE SFP+ modules include:

● Smallest 10G form factor

● Commercial temperature (0 to 70°C) only

● Supports 10GBASE Ethernet only

● Hot-swappable input/output device that plugs in to an Ethernet SFP+ port of Cisco platforms

● Provides flexibility of interface choice

● Supports digital optical monitoring capability

● Cisco quality identification (ID) feature that enables a Cisco platform to identify - optics supported by Cisco

technology

● Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same

link

SFP-10G-LR=

Features and Benefits

●   Industry’s smallest 10G form factor for greatest density per chassis

●   Hot-swappable input/output device that plugs into an Ethernet SFP+ port of a Cisco switch (no need to power down if installing or replacing)

●   Supports “pay-as-you-populate” model for investment protection and ease of technology migration

●   Digital optical monitoring capability for strong diagnostic capabilities

●   Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link

●   Cisco quality identification (ID) feature enables a Cisco platform to identify whether the module is certified and tested by Cisco

SFP-10G-LR-S=  and X2-10GB-LR= are compatible as they have same specifications.

Cisco SFP+	Wavelength (nm)	Cable Type	Core Size (Microns)	Modal Bandwidth (MHz*km)***	Cable Distance*
Cisco SFP-10G-LR-S	1310	SMF	G.652	-	10km
Cisco X2-10GB-LR	1310	SMF	G.652	-	10 km

Cisco S-class optics with their attractive price has attracted many users since they came out last year. According to Cisco data sheet, S-class is only for Ethernet protocol, not for OTN (Optical Transport Network) or WAN-PHY (Wide Area Network Physics). In addition S-class optics have different temperature ranges with non-S-class optics. Therefore, if you don’t need any special long distance, temperature tolerances, or other special features, S-Class optics are cheaper and should be just fine for you. what's more, they are fully compatible with non S-class optics.
