Unusual wavelength for XFP-LR

[h4nr0ck]

Using 'show port' command on 7450 TiMOS-7.0.R19 I got the wavelength information of 10GBASE-LR-XFP was 1307nm, does anybody know why it can be like that?
As I know the wavelength of 10GBASE-LR-XFP is 1310nm as ITU-T standardization.

thanks,
.: han :.

Hello Hans,

I'm not an engineer so I don't know, but I wanted you to know I stock 7450/7750 new open box and refurbished switches/routers, processors, IOMs, MDAs, SFPs and XFPs should you have a need as you network grows. email is greg.elder@lordsnet.com

COuld be one of two things:
You're running a DWDM SFP (used in the ROADMs for DWDM multiplexing)
or there is an error with the XFP itself reporting.
Question I ask is, what's on the other end? Same thing and is it reporting the same wave length?
