Paragon-neo-S: Which optics/transceivers can I use?

Paragon-neo-S: Which optics/transceivers can I use?

Specific optical transceivers must be used with Paragon-neo-S PAM4 interfaces. These modules have been tested by Calnex to ensure they fulfil the requirements for functionality and performance needed to enable correct operation and guarantee the integrity of the timing measurements. Use of other modules may result in a failed test or incorrect result. More information regarding PAM4 transceivers can be found: https://calnexsolutions.atlassian.net/l/cp/dchS6Mxk

PAM4 modules with 56G electrical lanes are not supported on Paragon-neo-S. Please refer to the Paragon-neo instead.

PAM4 100G modules with 112G electrical lanes MUST be used with the Paragon-neo-S PAM4 SFP112 100G interfaces.

PAM4 400G modules with 112G electrical lanes MUST be used with the Paragon-neo-S PAM4 QSFP112 400G interfaces.

PAM4 800G modules with 112G electrical lanes MUST be used with the Paragon-neo-S PAM4 800G QSFP112-DD and OSFP interfaces.

Paragon-neo-S does not support NRZ interfaces. Do not plug transceivers into the NRZ interfaces on a Paragon-neo-S instrument.

DAC cable assemblies must not be used with Paragon-neo-S. Paragon-neo-S is not designed for use with DACs, which means that such links are unlikely to work and there is a possibility of damaging your instrument. Such damage is not be covered under CSS.
