HPE1990-4414

Aruba1000BASE-LX SFPLC Transceiver module

The HPEAruba1990-4414 is a 1000BASE-LX SFPtransceiver designed for long-range single-mode fiber connections up to 10 km over 9/125 µm SMF. Operating at 1310 nm with NRZ signaling, it delivers stable Gigabit Ethernet performance using a duplex LC connector. Fully compatible with Aruba, HPE, and ProCurve switches that support X121/LX optics (firmware versions with 4×4 part numbers like 1990-4414), this module is ideal for campus uplinks, data center interconnects, and remote switch backhaul links. It features Digital Optical Monitoring (DOM) per SFF-8472 for real-time tracking of power, temperature, and voltage×helping administrators proactively maintain fiber health and avoid link degradation.

Features

The 1990-4414 is engineered to meet SFPMSA standards and is fully supported across Aruba/HPEswitch lines including Aruba6100, 6300, 5400, and HPEFlexNetwork models, provided firmware supports the 1990-4414 part number or its revisions, such as J4859D. Compatibility often requires software version 10.06.0130 or newer on CX-based switches.Optical performance delivers a transmit power range of approximately -9.5 to -3 dBm, and receiver sensitivity of -20 to -3 dBm, yielding an optical link budget of ~7.5 dB×suitable for spans up to 10 km in typical SMF deployments. DOM telemetry enables monitoring of critical link metrics for proactive management.These transceivers are available new and refurbished. Resellers report pricing from $160 to $325, with genuine OEM units often offering longer warranty coverage or lifetime assurances via select vendors.

Advanced Options

This module provides dependable long-distance connectivity backed by HPE/Arubabrand reliability. With a solid optical power profile and receiver sensitivity that supports signals over degraded or aged fiber, links remain consistent across sustained use. DOM monitoring enables early detection of issues like connector contamination or fiber attenuation, improving uptime for critical backbone links.Using OEM-certified modules ensures compatibility with advanced switch diagnostics and management features, plus support for firmware updates and vendor maintenance. For existing Aruba/HPEswitch fleets, firmware revisions that list part number 1990-4414 guarantee full interoperability. Beware of third-party optics lacking certification, which may cause compatibility or warranty issues.
