We use the Flexoptix stuff too. It's been a good experience. You get a free Flexbox if you order a transceiver. If you use the tunables it means that your emergency spares box is much reduced in cost.

We (and our upstream AARNet) have had good experiences with FlexOptix, they do have a CWDM XFP transceiver as well here:

Not sure if it'll work in your ASR but I would have assumed so.....

You'll need the flexbox thing to code them to Cisco spec but I belive they give that away free in most cases?

Thanks,
Ayden Beeson

Hi All,

Any recommendations of a cheap and decent brand for passive DWDM units to split dark fibre into 10GE waves? Lengths from 8km to 25km. Using Cisco XFP DWDM optics.

(Our Cisco ASR1K LAN-PHY 10G SPAs seem to only support DWDM XFP optics, so it appears CWDM for 10GE isn't an option?)

We only need 2 waves at first, at most 8 in the future.


Thanks,
Will
