Detailed Specifications
HPE R9Q45A Aruba 1GbE 1000Base-T SFP Transceiver
Overview
The HPE R9Q45A is a high-reliability SFP (Small Form-factor Pluggable) transceiver designed to provide a 1 Gigabit Ethernet copper interface for compatible networking equipment. It serves a critical role in modern enterprise and data center networks by converting an SFP fiber optic port into a traditional RJ-45 copper port. This allows network administrators to seamlessly integrate copper-based devices into a fiber-centric infrastructure without requiring a dedicated copper-port switch. This module is engineered for scenarios requiring stable, standards-based connectivity over existing copper cable plants. The primary operational benefit of the R9Q45A transceiver is its ability to extend the utility of high-density SFP-based switches, enabling connections to servers, endpoints, or other switches up to 100 meters away using standard Category 5e twisted-pair cabling. Its hot-pluggable nature is essential for maintaining network availability, as it can be installed or replaced without powering down the host device. Physically, the transceiver is installed into any compliant SFP port on a host device, such as an HPE Aruba switch. Logically, it functions as a standard 1000Base-T network port, supporting auto-negotiation for speed and duplex settings to ensure broad compatibility. Its compact design is ideal for maximizing port utilization in space-constrained rack environments, providing a flexible and cost-effective solution for media conversion at the network edge or core.
