HP compatible R9J30A Description
R9J30A is HPE's part number for a 400GBASE-FR4 QSFP-DD -- full name: HPE Networking X1E0 400G QSFP-DD FR4-WDM1300 2km LC Transceiver. Built for Aruba Networking platforms, specifically the CX 9300 and CX 10000 switch families. EdgeOptic's compatible ships with HPE-coded EEPROM so AOS-CX recognizes it cleanly.
Four CWDM wavelengths -- 1271, 1291, 1311, 1331 nm -- PAM4 at 106.25 Gbps per lane for 400G aggregate. LC duplex connector over OS2 single-mode fiber, 2 km maximum reach. 4.0 dB optical budget, TX -3.3 to +3.5 dBm, RX sensitivity -7.3 dBm. Under 11W power consumption. EML transmitters and PIN receivers. KP4 FEC (RS(544,514)) required on the host. DOM via CMIS 4.0 provides per-lane optical monitoring. Full specs on the 400GBASE-FR4 product page.
HPE's OEM transceiver for Aruba CX 9300 and CX 10000 families. The CX 9300-32D provides 32 QSFP-DD ports, each configurable for 400GbE, 2x200GbE, or 4x100GbE. With an FR4 module installed, the port runs in native 400GbE mode. EdgeOptic's compatible carries HPE-recognized EEPROM that AOS-CX accepts without generating warnings or alerts.
R9J30A is the orderable SKU. The full product name includes "X1E0" (product line identifier) and "FR4-WDM1300" (wavelength band reference -- the 1300 nm window covers the four CWDM channels). HPE uses the "R9J" prefix for QSFP-DD transceivers across their optical portfolio. On HPE QuickSpecs or buy.hpe.com, the module is listed under Networking QSFP-DD form factor transceivers.
The CX 9300-32D is HPE's high-density 400G switch for spine and core roles -- 32 QSFP-DD ports delivering up to 12.8 Tbps switching capacity when fully populated. In leaf-spine data center designs, FR4 modules in the CX 9300 connect to leaf switches over intra-building single-mode runs up to 2 km. The CX 10000 extends this architecture with distributed services processing built into the switch itself. For campus environments where the CX 9300 aggregates upstream traffic, the R9J30A provides 400G uplinks over existing LC-terminated single-mode plant -- no new MPO cabling investment needed.
IEEE 802.3cu-2021, 100G Lambda MSA 400G-FR4, QSFP-DD MSA, CMIS 4.0 compliant. DOM accessible on AOS-CX through standard interface diagnostic commands. 0 to 70 C commercial operating temperature. RoHS compliant.

Frequently Asked Questions
Is the HPE R9J30A compatible with the Aruba CX 9300-32D?
Yes. The CX 9300-32D has 32 QSFP-DD ports supporting 400GbE. R9J30A is HPE's own transceiver for this platform. EdgeOptic's compatible carries HPE EEPROM for AOS-CX.
Can the HPE R9J30A be used in non-HPE switches?
The OEM R9J30A carries HPE EEPROM -- other vendors may or may not accept it. EdgeOptic codes the compatible for the specified platform: Cisco, Arista, Juniper, or HPE.
