X2-10GB-ZR compatibility question

Hi All,

On the web site it says

Cisco X2-10GB-ZR: Supports link lengths of up to about 80 km on SMF. This interface is not part of the 10 Gigabit Ethernet standard but is built according to Cisco optical specifications.

I have a need to connect my 4507 chassis with the X2-10GB-ZR module to a Nortel switch at another site. Can anyone tell me if the Cisco ZR module is standards compliant, Nortel claim theirs to be, but don't want to waste a lot of money on a module that won't communicate ?

Many thanks

Re: X2-10GB-ZR compatibility question

Seeing that most of these modules are manufactured by a couple of major optics module vendors, I would assume they will interoperate.  I looked at Nortel's ZR XFP specs and they look very similiar in optical parameters.  From what I can gather, the IEEE has not ratified a ZR spec: 80km, 1550nm, SMF, so vendors developed one based on the SONET optics.

To put your mind at ease, you may want to contact Cisco (or a partner) to see if they can provide you a loaner, or try before you buy option.  This way you can test the solution for interoperability.  I know in the past they had these types of programs to offer their customers.

Hope this helps!

Or you can just buy cisco modules to both sides or nortel modules to both sides.
