Edgecore Networks compatible ET7402-ZR4 Description
ET7402-ZR4 is Edgecore Networks' part number for a 100GBASE-ZR4 QSFP28 — 100G over 80 km single-mode. Edgecore publishes a detailed compatibility list covering 20+ switch models for this optic, making it possible to verify support before ordering. Common deployment: data centre interconnect and metro backbone links between Edgecore disaggregated switches running SONiC or FBOSS. EdgeOptic's compatible matches the original specs and is coded for recognized operation on Edgecore platforms.
Four cooled EML channels at LAN WDM wavelengths near 1310 nm (1295.56, 1300.05, 1304.58, 1309.14 nm), 25G each, 103.125 Gbps aggregate. 4-channel PIN array with SOA preamplification on receive. TX power range is +2.0 to +6.5 dBm, RX sensitivity better than -26.9 dBm — 30 dB link budget on G.652 fiber. Single +3.3 V supply, LC duplex, QSFP28 MSA compliant, RoHS 6/6.
Per Edgecore's published qualification list (verify at edge-core.com before ordering): AGR400, AGR420, AGR560, AS8000 Minipack, CSR430, CSR440, DCS201, DCS202, DCS203, DCS204, DCS240, DCS500, DCS501, DCS510, DCS511, DCS520, DCS800, DCS801, DCS810, EPS201, EPS202, EPS203. If a specific Edgecore model isn't on this list, confirm compatibility with EdgeOptic sales before ordering.
RS-FEC (RS-528,514) on the host — mandatory, like every ZR4. No internal FEC in the module. Both ends must match, or the link won't come up.
Commercial temp range: 0 to +70 °C. Not industrial-rated — not suitable for uncontrolled roadside cabinets. DOM via standard QSFP28 I2C — TX/RX power, temperature, voltage all readable. Class 1 laser per IEC 60825-1. The cooled EML lasers include integrated TEC controllers for wavelength stability across the full operating range.
Short runs (under 15 km): use a 12 dB LC inline attenuator to prevent receiver overload. On the long end, 80 km on G.652 SMF with no amplification or dispersion compensation — as long as RS-FEC is enabled and total link loss stays inside the 30 dB budget. ZR4 cannot interoperate with LR4 at the far end. Both sides must be ZR4. DOM data is particularly valuable on these longer spans for detecting gradual fiber degradation before it causes outages.

Frequently Asked Questions
Which Edgecore switch models support the ET7402-ZR4?
Per Edgecore's list: AGR400, AGR420, AGR560, AS8000 Minipack, CSR430, CSR440, DCS201-204, DCS240, DCS500-501, DCS510-511, DCS520, DCS800-801, DCS810, EPS201-203. That covers 20+ models. If the specific model isn't listed, confirm compatibility with EdgeOptic sales before ordering.
What is the operating temperature range of the ET7402-ZR4?
0 to +70 °C, commercial grade. Not rated beyond 70 °C. ZR4 modules in general are designed for data centre and central office environments, not outdoor deployment. For extended temperature requirements, contact EdgeOptic sales.
Is RS-FEC required when using the ET7402-ZR4 compatible?
Yes, mandatory. RS-FEC (RS-528,514) on the host — no internal FEC in the module. Both ends must match. Verify during commissioning.
