Paragon-neo/100G: Which optics/transceivers can I use?

For PAM4 interfaces or SyncE Jitter testing, specific modules MUST be used. 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
For SyncE Wander and PTP on non-PAM4 interfaces, most modules should work correctly; known exceptions are detailed below. If you have a module that is not recognised, please let us know.
PAM4 100G modules MUST be used with the PAM4 100G interfaces.
PAM4 200G modules MUST be used with the PAM4 200G interfaces.
PAM4 400G modules MUST be used with the PAM4 400G interfaces.
PAM4 800G modules MUST be used with the PAM4 800G interfaces (paragon-neo-S only).
PAM4 400G modules may appear to operate correctly at 200G, but outliers (spikes in time error) may be seen, which will invalidate any results. Modules that don’t support 200G will show a warning indicating "not rate conformant" in the neo GUI.
DAC assemblies must not be used with Paragon-neo. Paragon-neo 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 would not be covered under CSS.
PAM4
To achieve optimal timing performance when testing using PAM4 optical interfaces, the specific optical modules as listed below MUST be used:

Note 2: | Calnex recommend using Flexoptix 100G PAM4 transceivers instead of Innolight 100G NRZ-PAM4 conversion transceivers whenever possible for the best generation and measurement accuracy. | ||||
Note 3: | Innolight use the same part numbers for TR-ZC13H-N00, TR-ZC13T-N00 and TR-ZC13L-N00 transceivers manufactured in China and Thailand although they exhibit different transmit and receive latencies. Please check that the software loaded on your Paragon-neo supports the transceivers that you are using. | ||||

SyncE Jitter
The modules listed below are those that MUST be used for SyncE jitter testing. These modules have been tested by Calnex to ensure that clock recovery can be bypassed and that they have sufficient bandwidth to allow the jitter performance of the device to be tested accurately. These modules are also known to operate correctly for PTP and SyncE Wander.

For SyncE wander and PTP at 1G and 10G we expect all correctly configured modules to operate correctly. At other line rates we expect most correctly configured modules to operate correctly.
Known Exceptions
High Power Modules
Some high power modules appear to have their transmitters disabled by default. To enable the transmitter, it is necessary to write to specific register locations in the module. If you are using a high power module and the module is recognised by Paragon but you cannot establish a link when connected from Paragon port 1 to port 2, please raise a ticket in the Calnex Service Desk (if you have valid CSS) or contact support@calnexsol.com.
These modules can be used with Paragon - enabling the transmitters is performed using a separate utility.
Other
Hirose, LTD1302-BH: Module does not support multi-byte read. Supported by Paragon-neo version 01.00 and later
FS, SFP28-25GSR-85: Some of these modules are configured in a way that Paragon-neo does not recognise; others appear to be OK
Coherent (Finisar), FTLX1472M3BCL: These modules support a range of rates from 8.5Gb/s to 11.3Gb/s for Fibre Channel, SDH/SONET and 10GbE. When the CDR is disabled (which Paragon will do under certain circumstances), the module will set the CDR for 8.5Gb/s Fibre Channel and so no link will be able to be established.
