Cisco sell "CWDM" GBICs, which are sort of on ITU wavelengths, but with a
wider spacing. I've not tried them to see if I can use them with the 15216
but "sparsely".

I'm currently using the 15454 to wavelength convert OC48 signals, but have
not to date seen a black-box wavelength convertor - I would also be interested
to know if such a beast exists. I think if you want to do this, you're stuck
with the Metro 1500 (or equivalent from someone else), which becomes very
expensive quickly.
