Hi Chris,

Thanks for your comment and let us apologize for the late answer.

We agree to code the wavelengths as per RFC6205 definition.
We'll circulate the new draft version soon.

Best Regards,

Gabriele

Subject: [CCAMP] using RFC6205 encoding of wavelengths in draft-galikunze-ccamp-g-698-2-snmp-mib-01 and draft-dharinigert-ccamp-g-698-2-lmp-01

Both draft-galikunze-ccamp-g-698-2-snmp-mib-0 and draft-dharinigert-ccamp-g-698-2-lmp-01 specify wavelengths in THz.   This would also require specifying the floating-point representation for proper encoding.

Instead, I would suggest that these drafts use the wavelength encoding defined in RFC6205.  This will allow the absolute wavelength values to be encoded as integer values for the encoded grid and channel spacing.  It also avoids creating multiple wavelength encodings in documents produced by CCAMP.
