Edgecore Networks compatible ET7402-ZR4 Description
EdgeOptic's ET7402-ZR4 compatible is an Edgecore-coded 100GBASE-ZR4 QSFP28 rated for 80 km on single-mode fiber. Edgecore Networks publishes the original qualification list for the ET7402-ZR4 across their open-network switch portfolio; the EdgeOptic compatible matches that spec with EdgeOptic EEPROM coding for the same 100G QSFP28 host ports.
Four cooled EML channels at LAN-WDM wavelengths 1295.56, 1300.05, 1304.58, and 1309.14 nm, 25.78 Gbps each lane, 103.125 Gbps aggregate over two single-mode fibers (TX and RX) on an LC duplex connector. SOA + PIN photodetector array on receive. TX power +2.0 to +6.5 dBm per lane, 30 dB optical link budget on G.652 fiber. NRZ direct-detection, DOM via the standard QSFP28 I2C interface. 100GBASE-ZR4 is MSA-extended from IEEE 802.3ba LR4 to reach 80 km.
Host RS-FEC is mandatory. ZR4 closes the 80 km link with RS(528,514) per IEEE 802.3 Clause 91 running on the host MAC; the module carries no internal FEC. Both ends must have RS-FEC enabled, otherwise the link will not stabilise. On Edgecore SONiC switches the FEC mode is configurable per port; verify RS-FEC is set on each 100G ZR4 interface during commissioning.
Compatible with Edgecore switch products. Verify against Edgecore's transceiver qualification list at edge-core.com before deploying; Edgecore publishes the authoritative qualification table per switch model and revises it as new platforms are released.
Operating temperature 0 to +70 °C commercial grade, 3.3 V single supply. Class 1 laser safety, RoHS 6/6. DOM via standard QSFP28 I2C exposes TX/RX power, temperature, and supply voltage to the host NMS. On short spans the receiver can saturate, especially toward the +6.5 dBm upper end of the TX range; insert an LC inline attenuator on the receive side, sized to bring the received power into the receiver's operating window for the deployed TX power. Sibling Cisco QSFP-100G-ZR4-S and Arista QSFP-100G-ZR4 compatibles cover the same 80 km LAN-WDM ZR4 standard with vendor-coded EEPROM for those host platforms.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. To confirm Edgecore switch compatibility for your specific deployment or for SONiC FEC configuration guidance, contact our sales team.
Frequently Asked Questions
Does the ET7402-ZR4 require RS-FEC to be enabled, and what happens if one end has it disabled?
Yes, mandatory at both ends. 100GBASE-ZR4 closes the 80 km link using host RS(528,514) FEC per IEEE 802.3 Clause 91; the module carries no internal FEC. If one end has RS-FEC disabled the link will not stabilise. On Edgecore SONiC switches the FEC mode is configurable per port; verify RS-FEC is set on each 100G ZR4 interface before bringing the link up.
Which Edgecore switch models support the ET7402-ZR4?
Edgecore Networks publishes the qualification list per switch model on the official ET7402-ZR4 product page; the list is revised as new switch platforms are released, so the live page is the authoritative source rather than a static snapshot. Refer to edge-core.com/product/et7402-zr4 for the current switch compatibility table before ordering.
