400G QSFP-DD FR4 Transceiver

ET7502-FR4

Edgecore’s QSFP-DD 400Gbps transceiver module is designed for optical communication applications over 400

Gigabit Ethernet links of up to 2 km single mode ﬁber. This product has 8 independent electrical input/output chan-

nels that convert 50Gbps (PAM4) electrical input data to 4 channels of 100Gbps (PAM4) optical signals. The electri-

cal interface of the module is compliant with the 400GAUI-8 interface as deﬁned by IEEE 802.3bs, and compliant

with QSFP-DD MSA.
