I wonder if someone can help me with a seemingly simple but elusive question. I'm looking to
make a purchase of several Cisco SFP-10G-LRM modules to support 10Gb communications over our
OS2 fibre infrastructure. All runs are less than 300m so this is cost effective compared to
On the other end of the fibre will be some servers using Intel E10GSFPLR optics at 10Gb.
My question is this - are these optics compatible for the situation I've described? I've done
some searching and can't find any definite information either way, despite these being popular
choices (I guess).
Any help is appreciated.
Thank you for contacting Intel.
The http://www.intel.com/content/dam/doc/product-brief/ethernet-sfp-optics-brief.pdf Intel® Ethernet SFP+ LR Optic (E10GSFPLR) can support 10GBASE-LR 10G Ethernet and 1000BASE-LX 1G Ethernet only. In relation to your concerns on compatibility with 10GBASE-LRM, I will help you check on this further.
I will update you on my findings.
Thanks Sandy. For reference, the SFP-10G-LRM runs at 1310nm the same as the Intel optics, so I am hopeful. We run plenty of Cisco-Cisco over OS2 (<300m) without issue but haven't started deploying the Intel-Cisco scenario above. We're looking at around 100 pairs just now so the saving over using SFP-10G-LR is significant if you can validate.
I'm sorry to inform you that we can confirm on compatibility between Intel E10GSFPLR and Cisco SFP-10G-LRM as we aren't able to perform thorough testing on this type of connection.
We suggest that you may further check this with Cisco*.
Again, thank you for contacting Intel.
