400G QSFP-DD DR4 Transceiver

ET7502-DR4

Edgecore’s QSFP-DD 4*100Gbps transceiver module is designed for optical communication applications over 400

Gigabit Ethernet links of up to 500 m of single mode ﬁber. This product has 8 independent electrical input/output

channels that convert 50Gbps (PAM4) electrical input data to 4 channels of 100Gbps (PAM4) parallel optical

signals over 1310 nm wavelengths. The electrical interface of the module is compliant with the 400GAUI-8

interface as deﬁned by IEEE 802.3bs, and compliant with QSFP-DD MSA.
