400Gbps High-Speed Networking

The HPE R9J30A provides a total optical data rate of 400Gbps, making it suitable for high-bandwidth data center and enterprise networking environments.

400Gbps connectivity helps support bandwidth-intensive applications such as data center aggregation, server connectivity, cloud infrastructure, storage networking and high-capacity interconnects.

QSFP-DD Form Factor

The R9J30A uses the QSFP-DD form factor. HPE identifies the product type specifically as QSFP-DD in its technical specifications. ([HPE](https://www.hpe.com/dk/en/product-catalog/options/pip.specifications.transceivers.1014678602.html))

QSFP-DD provides a compact, high-density optical interface for modern high-speed network equipment and enables 400Gbps connectivity in compatible networking platforms.

FR4-WDM1300 Technology

The R9J30A uses FR4-WDM1300 optical technology. HPE's Comware documentation identifies four wavelength lanes at 1271nm, 1291nm, 1311nm and 1331nm. ([HPE Aruba Networking](https://arubanetworking.hpe.com/techdocs/comware/UG/cmwr/HPECmrw-basedDevicesTransceiverModulesUG_400G_6W100.pdf))

Wavelength-division multiplexing allows the four optical lanes to operate over the same single-mode fiber path, providing 400Gbps aggregate connectivity through the QSFP-DD module.

2km Transmission Distance

The R9J30A supports a maximum transmission distance of 2km. HPE officially lists 2km as the maximum distance for this transceiver. ([HPE](https://www.hpe.com/dk/en/product-catalog/options/pip.specifications.transceivers.1014678602.html))

This makes the module suitable for short- to medium-distance single-mode fiber links between network devices within data centers, campuses and nearby facilities.

LC Connector

The R9J30A uses a duplex LC connector. HPE's 400G Comware documentation categorizes the R9J30A among QSFP-DD optical transceivers using LC connectors. ([HPE Aruba Networking](https://arubanetworking.hpe.com/techdocs/comware/UG/cmwr/HPECmrw-basedDevicesTransceiverModulesUG_400G_6W100.pdf))

The LC interface provides a compact fiber connector suitable for high-density data center patching and structured optical cabling.

Single-Mode Fiber

The R9J30A is designed for single-mode fiber (SMF) with a documented fiber diameter of 9/125 µm. ([HPE Aruba Networking](https://arubanetworking.hpe.com/techdocs/comware/UG/cmwr/HPECmrw-basedDevicesTransceiverModulesUG_400G_6W100.pdf))

Use compatible single-mode optical cabling and LC connectors when deploying this transceiver.

Four Optical Wavelengths

These four wavelengths form the FR4-WDM optical architecture used by the R9J30A for 400Gbps transmission. ([HPE Aruba Networking](https://arubanetworking.hpe.com/techdocs/comware/UG/cmwr/HPECmrw-basedDevicesTransceiverModulesUG_400G_6W100.pdf))

Optical Power Parameters

HPE's Comware documentation specifies transmit power of approximately -3.3 to +3.5 dBm per lane and receive power of approximately -7.3 to +3.5 dBm per lane for R9J30A. ([HPE Aruba Networking](https://arubanetworking.hpe.com/techdocs/comware/UG/cmwr/HPECmrw-basedDevicesTransceiverModulesUG_400G_6W100.pdf))

Optical power and link-budget requirements should be checked when designing longer fiber links or deploying the module through patch panels and other optical infrastructure.

HPE Networking Compatibility

HPE lists the R9J30A as an HPE Networking X1E0 transceiver. HPE's Comware documentation also lists R9J30A in its 400G QSFP-DD transceiver documentation. ([HPE](https://buy.hpe.com/us/en/Options/Transceiver-Options/Transceivers/Networking-QSFP-DD-Form-Factor/p/R9J30A))

HPE's Comware switch documentation also lists R9J30A among supported QSFP-DD transceiver options. ([HPE Aruba Networking](https://arubanetworking.hpe.com/techdocs/comware/UG/cmwr/HPECmrw-basedDevicesTransceiverModulesUG_400G_6W100.pdf))

Actual compatibility depends on the exact switch model, firmware and supported transceiver matrix. Always verify the target HPE Networking device before installation.
