400G QSFP-DD Loopback Module

产品介绍

BizLink® QSFP-DD loopback module is designed to test QSFP-DD ports effectively by looping back electrical signal. This module is a 8-channel transmission which supports data rates of up to 400Gbps. QSFP-DD loopback are backwards plug compatible with existing 100G based systems and support 200G (8 channels @ 25G NRZ) or 400G (8 channels @ 50G PAM 4) signaling transmission.
