Interface Incompatibilities

Due to hardware restrictions, some of our traffic interfaces do not interoperate with some hardware (e.g. restrictions to SFP modules, restrictions to direct-attached-cables...).
In this article, we list incompatibilities known to us.  If you encounter other equipment not working with ByteBlower, please inform us using our support portal.

Due to our hardware vendor, we are restricted from using Intel SFP+ modules

• Customers reported issues with Twinax DAC cables.
• We've noticed issues with 1Gbit/s SFP transceivers.
  • Copper SFP (1Gbit/s) causes system crashes.
  • No traffic was possible over Fiber SFP (1Gbit/s)
• 10Gbit/s NBASE-T SFP+ transceivers have limited connectivity. Check essential connectivity before using these with the ByteBlower 4100. For example:
  
  • No traffic was possible between the 'native' 10Gbit/s on the M4300
  • No issues were reported between 2 copper SFP+ of the same manufacturer.
• We successfully use optics from FS.com.

No known issues. Do note that at the time of writing (Oct 2020) there are several competing 100Gbit/s Ethernet standards.
Don't hesitate to contact us with questions or to report your experience.

This switch is used as an 8-port NBASE-T add-on. This unit is supplied with a custom configuration for the ByteBlower systems. This config is tested continuously.

• Only use Optic transceivers on the SFP+ ports.
  No functional copper SFP+ (NBASE-T) transceivers found yet.

This is also called the Flex switch due to its flexibility in configuration. The following limitations were found.

• Copper 10Gbit/s SFP+ (NBASE-T) won't negotiate to lower speeds. Connect these transceivers only with other 10Gbit/s links.

This switch is used for the 100Gbit/s ByteBlower 5100.

• Copper 10Gbit/s SFP+ (NBASE-T) won't negotiate to lower speeds. Connect these transceivers only with other 10Gbit/s links.
