Thor-400G-7S-1P

Thor-400G-7S-1P is a 7-speed (400GE, 200GE, 100GE, 50GE, 40GE, 25GE, 10GE) dual media test module with the unique capability of being able to test both PAM4 and NRZ speeds.

7-speed dual-media test module
Thor-400G-7S-1P is the only 400GE test module on the market that lets you test both PAM4 and NRZ traffic. It can test seven different Ethernet network speeds: 400GE, 200GE, 100GE, 50GE, 40GE, 25GE and 10GE, as well as Auto-Negotiation and Link Training (AN/LT).

This unique flexibility is provided via two physical transceiver cages – one supporting QSFP-DD/56/28/+ transceivers, and the other supporting QSFP56/28/+ transceivers. Both cages can be active simultaneously – except when the QSFP-DD cage runs 400GE, 2 x 200GBASE-CWDM4, 1 x 200GBASE-SR8, 4 x 100GBASE-DR or 8 x 50GBASE-SR/CR.

The Thor-400G-7S-1P supports the latest high-speed Ethernet standards 802.3bs and 802.3cd, as well as legacy standards.

The result is a highly versatile solution for performance and functional testing of network infrastructure and Ethernet equipment that support 400GE including switches, routers, NICs, TAPs, packet-brokers, and backhaul platforms.
