Ethernet Test Tools
Xena’s Thor-100G-5S-4P test module can test five different Ethernet network speeds – 100GE, 50GE, 40GE, 25GE and 10GE. This unique flexibility is provided via two physical transceiver cages – one supporting QSFP-DD/56/28/+ transceivers, and the other supporting QSFP56/28/+ transceivers.
The QSFP-DD cage can support the following speeds and ports: 1x100G, 2x100G, 4x100G, 2x50G, 4x50G, 8x 50G, 1x40G, 4x25G, and 4x10G Ethernet test ports. The QSFP56 cage can support the exact same speeds except for 4x100G or 8x50G Ethernet. Both cages can be active simultaneously except when the QSFP-DD cage runs 4x100G or 8x50G.
Thor-100G-5S-4P is the only test module on the market that can test both NRZ & PAM4 speeds, plus perform Auto-Negotiation and Link Training (AN/LT) with a comprehensive level of interoperability testing.
The result is a highly versatile solution for performance and functional testing of network infrastructure and Ethernet equipment that support 100GE including switches, routers, NICs, TAPs, packet-brokers, and backhaul platforms.

QSFP-DD cage • 4 x 100GBASE-CR2, or 4 x 100GBASE-DR (PAM4 / 802.3cd) For the QSFP56 cage – same as QSFP-DD minus support for 4 x 100GBASE-DR, 4 x 100GBASE-CR2 and 8 x 50GBASE-SR/C Actual interface options depend on the capabilities of the inserted transceiver. Both cages can be active simultaneously except when the QSFP-DD cage runs 4 x 100GBASE-DR or 8 x 50GBASE-SR/CR. Both cages must run with the same base interface configuration (e.g. 2 x 50G).
