HPE AW537A

1000Base-T Gigabit Ethernet Copper SFP Transceiver module

The HPE AW537A is a versatile copper SFP Transceiver module designed for 1000Base-T Gigabit Ethernet. It enablescopper-based network connectivity via standard RJ-45 ports and accommodates CAT5e/CAT6 cabling for links up to 100 m at 1 Gb/s. This compact, hot-swappable module fits into any compatible SFP slot, offering flexible deployment in both switches and servers. Compliant with industry standards such as IEEE 802.3ab, SFP MSA, INF-8074i, and SFF-8472 for diagnostics, it's widely used in enterprise, campus, and data center environments for reliable, cost-effective copper networking.

Features

The AW537A is designed as an easy-to-deploy copper-based transceiver, ideal for 1 Gb Ethernet links where fiber isn’t necessary. Unlike optical modules, it uses an RJ-45 connector that supports auto-negotiation, auto-MDI/MDIX, and full-duplex gigabit speeds, simplifying connectivity with existing copper infrastructure. It delivers dependable performance over up to 100 meters of CAT5e/CAT6 cable. Engineered for broad compatibility, this module adheres to SFP MSA and IEEE 802.3ab specifications and supports digital diagnostics monitoring (DDM), enabling real-time monitoring of temperature, voltage, and signal statistics via I²C/SFF. This helps in proactive maintenance and ensuring reliable network health. 

Advanced Options

With a low power draw around 1 W, it’s largely compatible with HPE B-series switches, BladeSystem, and SAN Director deployments. Its hot-swappable design ensures minimal service disruption and flexible network upgrades. The AW537A offers robust and dependable 1 Gb performance across copper cabling, making it a practical and cost-effective choice for many network upgrade paths. Its support for DDM provides continuous visibility into operational parameters, helping to detect issues early before they affect uptime.
