HPE 1990-4395 

Aruba 1990‑4395 ProCurve LC SX SFP Transceiver Module

The HPE Aruba 1990‑4395 (ProCurve X121) SFP Transceiver Module provides reliable Gigabit Ethernet connectivity over multimode fiber. Designed for use with Aruba and HPE ProCurve switches and select network equipment, it operates at 1 Gb/s using the 850 nm wavelength and LC duplex connector. Supporting distances up to 550 m over OM2 fiber and 275 m over OM1, it’s ideal for enterprise campus backbones, server uplinks, or switch-to-switch links in building networks. With built‑in Digital Optical Monitoring (DOM), administrators can monitor optical power and temperature in real time—allowing proactive maintenance and enhanced link reliability. The compact, hot-pluggable SFP design ensures ease of deployment and flexibility in dense rack environments.

Features

This module supports the IEEE 1000BASE‑SX standard, transmitting at 850 nm over multimode fiber using LC duplex connectors. It achieves reliable link performance up to 550 m on OM2 fiber and approximately 275 m on OM1 fiber strands . DOM functionality enables live tracking of optical parameters—such as transmit/receive power levels and internal temperature—which helps in maintaining link health and operational efficiency Compatible with a wide range of HPE and Aruba switches, including the Aruba2530, 2920, 2930F, and 3810M series, the transceiver integrates seamlessly into existing network topologies As a gigabit fiber optic module, it reduces electromagnetic interference and supports secure, high-quality data transmission over existing multimode cable plants—making it a cost-effective upgrade for expanding fiber links or transitioning from copper fabrics.

Advanced Options

This plug-in SFP module is hot-swappable, allowing live insertion or replacement without shutting down connected devices. Its compact form factor conserves space while enabling flexible port configuration across switch units. Compliance with RoHS, WEEE, and REACH standards also ensures it meets environmental and regulatory guidelines Overall, this transceiver is well-suited for IT professionals seeking OEM-certified optical modules with broad compatibility and simple diagnostics.
