HPE 1990-3816 

Aruba 1000Base‑T SFP (RJ‑45) Transceiver module

The HPE Aruba 1990‑3816 is a copper-mode SFP Transceiver module that enables 1 Gigabit Ethernet via RJ-45 Cat‑5e/Cat‑6 cabling over distances up to 100 meters. Ideal for environments lacking fiber infrastructure, this module allows flexible integration into Aruba or HPE switches and routers with SFP ports. This plug‑and‑play module offers a cost-effective copper uplink alternative with reliable performance, making it suitable for campus networks, small business wiring, edge deployments, and server connectivity.

Features

Operating under the IEEE 1000Base‑T standard, this module transmits over standard twisted‑pair copper cabling, offering up to 1 Gbps data throughput. It’s designed for seamless interoperability with Aruba and HPE networking devices that support SFP SFPRJ‑45 modules. With a compact SFPform factor, the module is hot‑swappable and easily installed without disrupting network operations. The module features support for QoS and adheres to RoHS/WEEE compliance, adding sustainability to its deployment credentials. Typical use scenarios include uplinking access-layer switches, connecting server ports, or bridging copper-based segments in fiber transitions

Advanced Options

This Transceiver module is built for reliable, consistent gigabit performance over existing copper cabling. With power consumption under 1 W, it minimizes thermal stress and allows dense port configurations without overheating. Its SFP design enables easy hot‑swappable installation and deployment in production environments without downtime.
