HPE Aruba Networking Q9G82A 40Gbps QSFP+ LC ER4 40KM SMF Transceiver
The HPE Aruba Networking Q9G82A is a 40Gbps extended-reach QSFP+ optical transceiver designed for high-speed Ethernet connectivity over single-mode fiber. It uses four optical lanes and a Duplex LC interface for long-distance network connections.
The transceiver supports transmission up to 30km over single-mode fiber without FEC. With Forward Error Correction (FEC) enabled at both ends of the engineered link, the maximum reach can extend to 40km. It is suitable for network aggregation, enterprise backbone, telecommunications, and extended-reach data center connectivity.
40Gbps ER4 Optical Connectivity
The Q9G82A provides 40Gbps connectivity using four 10Gbps NRZ optical lanes. Its ER4 architecture is designed for extended-reach single-mode fiber applications where standard short-range 40G optics are insufficient.
The module is designed for compatible HPE Aruba Networking equipment supporting the corresponding QSFP+ optical transceiver specifications.
Extended-Reach Single-Mode Fiber Transmission
The transceiver operates over 9/125µm single-mode fiber. HPE specifies a transmission distance of 30km without FEC and up to 40km when FEC is used at both ends of the engineered link.
Four-Channel WDM Architecture
The module uses four optical wavelengths at 1271nm, 1291nm, 1311nm, and 1331nm, with each lane operating at 10Gbps NRZ. This wavelength-division architecture enables 40Gbps transmission over a duplex single-mode fiber connection.
QSFP+ and Duplex LC Interface
The compact QSFP+ form factor provides a high-density interface for compatible 40Gbps network equipment. The optical connection uses a Duplex LC connector for two-strand single-mode fiber.
Digital Optical Monitoring
The Q9G82A supports Digital Optical Monitoring (DOM), allowing compatible host equipment to monitor supported optical operating parameters for network management and troubleshooting.

Compatibility
The HPE Aruba Networking Q9G82A is designed for compatible HPE Aruba Networking equipment supporting 40G QSFP+ LC ER4 optical transceivers. Before installation, verify the host device's supported transceiver list, QSFP+ port requirements, fiber specifications, and FEC capabilities.
For a 40km deployment, FEC must be supported and enabled at both ends of the engineered link. For shorter single-mode fiber connections, HPE specifies the use of a 9dB attenuator to address the module's receive-power range where applicable.
