The Q8J73A-C is an HPE M-Series compatible 100GbE QSFP28 optical transceiver using 1310 nm PSM4 technology to deliver 100 Gbps over up to 500 m of single-mode fiber.
This transceiver is compatible with all HPE M-Series and FlexFabric switches that feature QSFP28 ports, including the Aruba 8320, 8400, 5400R, and 5700 series.
The module supports a maximum link length of 500 meters over single-mode fiber using PSM4 parallel optics.
It uses a standard MPO/MTP 12-fiber connector for PSM4 parallel transmission across four lanes.
The Q8J73A-C operates at a nominal wavelength of 1310 nm and conforms to IEEE 802.3bm PSM4 standards for 100GbE.
Yes. The module is hot-pluggable, allowing installation and removal without powering down the switch.
Typical power consumption is 4.5 W per transceiver, well within the QSFP28 thermal budget.
The transceiver supports an operating temperature range from 0 °C to 70 °C (32 °F to 158 °F).
Yes. It includes a one-year limited warranty that covers manufacturing defects and performance issues.
Align the transceiver with the QSFP28 slot, gently slide it into place until it clicks, then verify link status via the switch’s LED indicators or management console.
Yes. The transceiver meets RoHS directives for restriction of hazardous substances in electronic equipment.
Each module undergoes factory validation in HPE switches under full traffic load to guarantee compatibility and performance.
