SFP 10G-LR to X2-10GB-LX4

[Juan Manuel Uribe Ruiz]

Hi everyone

I'm trying to connect one Cisco Nexus 5548UP with a SPF 10G-LR to a one Cisco Cat 6506-E with a X2-10G-LX4 with a MMF but the connection do not goes up, I think the 10G-LR works in the same wavelength of 1300-nm, any clue about this?

I guess I need a 10G-LR-X to in the side of the nexus =(

Thanks in advance

The LX4 interface actually uses four (4) data streams (wavelengths) across each of the two MMF fibers. See Table 2 here:

It is not compatible with the more commonly used 10Gbase-LR which only use a single wavelength per fiber.

Thanks Marvin

That is really sadly right...

We need to change the LX4 with another kind of X2
