Edgecore Networks compatible ET7402-LR4 Description
EdgeOptic's ET7402-LR4 compatible is an Edgecore Networks-coded 100GBASE-LR4 QSFP28 transceiver built on the EdgeOptic 100G-QSFP28-10 platform. The compatible carries Edgecore-recognized EEPROM identifiers so the host switch surfaces the expected ordering code in management telemetry, and the module slots into a standard QSFP28 cage with the same insertion, hot-swap, and DDM behavior as the OEM module.
The optical interface follows IEEE 802.3ba Clause 88 100GBASE-LR4. Four 25.78 Gbps NRZ lanes ride the LAN WDM grid at 1295.56, 1300.05, 1304.58, and 1309.14 nm, then multiplex onto a single LC duplex pair of single-mode fiber. The 6.3 dB optical path loss budget supports a full 10 km reach on G.652 SMF. Power dissipation stays at 3.5 W or less on a single 3.3 V supply, the operating temperature window is 0 to 70 C commercial, and the module reports DDM telemetry per SFF-8636 for tx power, rx power, bias current, supply voltage, and case temperature. Class 1 laser safety, RoHS compliance, and CE marking apply.
Edgecore Networks supplies open-networking switching that typically runs SONiC, Open Network Linux, or Cumulus Linux. EdgeOptic's compatible matches the original optical and electrical specifications and carries the ET7402-LR4 ordering code so procurement records and chassis inventory output stay consistent with the Edgecore part numbering. Typical deployment scenarios include ISP aggregation and backbone uplinks, hyperscale and enterprise data center fabric uplinks, and core network site interconnects on QSFP28 hosts that accept third-party 100GBASE-LR4 optics per the QSFP28 MSA. Verify third-party optic acceptance against the specific Edgecore switch model and operating system release before ordering.
Verify the entry for the specific Edgecore switch model and operating system version in the vendor's transceiver compatibility documentation before deployment.
