Hi Anand,
Here is the link for LR4 support:
LR4 Support on Mellanox Switches
It says:
Here is the list of Mellanox switches and ports that supports LR4 module (Long Reach - QSFP), OPN: MC2210511-LR4 up to 10Km:
- SX1036 use ports 1,3,33,35 only.
- SX1024 use ports 50,52,54,56,58,60 only.
- SX1012 all ports
- SX1710 all ports
- TX6000/6100 all long-haul ports
Can the Switch support Finisar LR4 QSFP module?
