HPE 1990-4750

Multi‑mode 1 Gbps SFP LC SX Transceiver Module

The HPE Aruba1990‑4750 is a 1 Gbps SX SFP Transceiver Module designed for multi‑mode fiber (MMF) networks over OM2 / 50 µm cabling. With LC duplex connectors and support for up to ~500 meters (1640 ft), it enables short‑haul fiber links for edge switches and server aggregation. Ideal for HPE Aruba Instant On or OfficeConnect environments, it offers plug‑and‑play operation and clean integration into fiber uplinks. This module is tailored for SMBs, campus networks, and branch deployment, delivering reliable gigabit speed with minimal latency and low power consumption.

Features

This multimode fiber SFP transceiver supports IEEE 1000Base‑SX standards and operates at an 850 nm wavelength. With compatibility for OM2 fiber type, it reaches distances up to approximately 500 m (when using 50/125 µm fiber) or about 400 m on OM3, translating to around 1640 feet maximum reach . It includes Digital Optical Monitoring (DOM) support for real‑time RX/TX power and temperature readings, aiding diagnostics and proactive maintenance The compact SFP form factor ensures compatibility with standard fiber ports on Instant On and Aruba switches, with hot‑swap capability and IEEE networking compliance.

Advanced Options

This SFP transceiver is engineered for reliable gigabit performance in multi‑mode fiber environments. Operating under 1 W power consumption, its low‑power design helps maintain switch thermal stability. DOM functionality allows network administrators to monitor link health,
