HP compatible R9J30A Description
EdgeOptic's R9J30A compatible is an HPE Aruba-coded 400GBASE-FR4 QSFP-DD transceiver, programmed with HPE-recognized EEPROM so AOS-CX accepts the module on insertion. Same 2 km duplex single-mode reach, same LC/UPC connector, and same optical and electrical envelope as HPE's original part. The full HPE product name listed in the HPE Store catalog is HPE Networking X1E0 400G QSFP-DD FR4-WDM1300 2km LC Transceiver; R9J30A is the orderable SKU.
Four CWDM wavelengths at 1271, 1291, 1311, and 1331 nm multiplex onto a single duplex LC pair. PAM4 modulation at 53.125 GBaud per lane delivers 400 Gb/s aggregate throughput. EML transmitters drive each wavelength channel; PIN photodiode receivers handle the inbound side. TX power is -3.3 to +3.5 dBm per lane, RX sensitivity is -7.3 dBm. The 4 dB optical link budget covers a 2 km OS2 span with margin for patch panels and splices in normal data center cabling environments. Power under 10 W. Full 400GBASE-FR4 specifications cover the rest.
Works on the Aruba CX 9300-32D, a 32-port QSFP-DD switch supporting 100/200/400G client ports. Verify R9J30A support against the HPE AOS-CX Transceiver Guide for any other CX platform and the specific AOS-CX release in service before ordering, since the qualified-optic table is the authoritative compatibility reference for AOS-CX.
HPE Aruba layers a proprietary EEPROM authentication check on AOS-CX that goes beyond the standard QSFP-DD vendor-ID fields. A third-party transceiver with stock EEPROM can fail authentication on AOS-CX even when allow-unsupported-transceiver is set. EdgeOptic programs the R9J30A compatible specifically for the target Aruba CX platform; specify the chassis model and AOS-CX release at order time so the EEPROM image matches what the platform expects.
Conforms to IEEE 802.3cu, 100G Lambda MSA 400G-FR4, QSFP-DD MSA, and CMIS 4.0. CMIS exposes per-lane TX and RX optical power, module case temperature, supply voltage, and laser bias current over standard I2C, so DOM integrates with the AOS-CX show transceiver toolchain through the same monitoring path used by HPE-branded optics. KP4 RS-FEC (RS(544,514)) is required from the host ASIC to meet the 400GBASE-FR4 PAM4 BER target. Class 1 laser safe per IEC 60825-1, CE and RoHS certified, commercial temperature 0 to 70 °C.
FR4 fits 400G data center interconnect, leaf-spine uplinks, and aggregation above a 100G leaf layer. Duplex LC patching keeps structured cabling simple where the existing single-mode plant already uses LC, the alternative to MPO-12 parallel optics on DR4. 2 km covers most intra-campus and metro-edge runs.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Made to order with a 2-week lead time and lifetime warranty included. For volume pricing or platform-specific EEPROM coding requests, contact our sales team.
Frequently Asked Questions
Does the HPE R9J30A compatible work on the Aruba CX 9300-32D?
Yes. The CX 9300-32D is a 32-port QSFP-DD switch that supports 400G client ports, and R9J30A is the matching 400GBASE-FR4 module in HPE's Aruba transceiver lineup. EdgeOptic's compatible carries HPE-recognized EEPROM for AOS-CX, so the chassis accepts the module on insertion. For any other CX platform, verify R9J30A support in the HPE AOS-CX Transceiver Guide for the specific chassis and AOS-CX release before ordering.
Will a compatible R9J30A clear AOS-CX authentication if allow-unsupported-transceiver is enabled?
AOS-CX layers a proprietary EEPROM check on top of the standard QSFP-DD vendor-ID fields. A generic third-party module can fail that check on Aruba CX even when allow-unsupported-transceiver is set, and the link stays down. EdgeOptic programs the R9J30A compatible specifically for the target CX platform so the EEPROM image matches what AOS-CX expects, which removes the workaround dependency. Specify the chassis model and AOS-CX release at order time.
