100G QSFP28 PSM4 Transceiver

ET7402-PSM4-2

Edgecore’s ET7402-PSM2-2 QSFP28 transceiver modules are designed for use in 100 Gigabit Ethernet links of up

to 2 km of single mode ﬁber. They are compliant with the QSFP28 MSA and portions of IEEE P802.3bm . Digital

diagnostics functions are available via the I2C interface, as speciﬁed by the QSFP28 MSA. The QSFP28 full-duplex

optical module oﬀers 4 independent transmit and receive channels, each capable of 25Gb/s operation for an

aggregate data rate of 100Gb/s.
