The Freya-800G-4S-1P-OSFP test module supports four Ethernet network speeds – 800GE, 400GE, 200GE and 100GE using 112G SerDes (PAM4 112G).

The module supports OSFP-compatible transceivers and the following speeds: 1x800GE, 2x400GE, 4x200GE and 8x100GE.

Freya-800G-4S-1P-OSFP is a highly versatile solution for performance and functional testing of network infrastructure and Ethernet equipment including switches, routers, NICs, TAPs, packet-brokers, and backhaul platforms.

Freya-800G-4S-1P-OSFP is unique on the market with its ability to test up to 800GE with 112G SERDES (PAM4 112G) on OSFP optics and DACs and perform Auto-Negotiation and Link Training (AN/LT). Received signals can be analyzed the advanced signal integrity view, which provides visual information on the quality of the signal.
