HP 1990-4116

Aruba 1990‑4116 1000BASE‑LX SFP LC Transceiver module(GigE)

The HP Aruba 1990‑4116 is a 1000BASE‑LX SFP Transceiver module engineered to deliver stable Gigabit Ethernet over single-mode fiber up to 10 km. Operating at 1310 nm with NRZ encoding, it uses a duplex LC connector and is fully compliant with Gigabit Ethernet SFP standards. As an OEM-certified module, it’s validated across Aruba /HP switch lines—such as the 6100, 6300, 5400 series—provided the firmware supports part number 1990‑4116 or variant. Designed for campus aggregation, data center uplinks, or long-distance fiber interconnects, it supports Digital Optical Monitoring (DOM) per SFF‑8472 for real-time diagnostics like transmit/receive power, voltage, and temperature

Features

Engineered to industry-standard SFP MSA specifications, the 1990‑4116 module supports up to 1 Gb/s (1000BASE-LX) over single-mode fiber. The optical transmission range works reliably up to 10 km over 9/125 µm SMF. Typical performance includes transmit power between –9.5 to –3 dBm and receiver sensitivity between –20 to –3 dBm, providing an optical link budget of approximately 7.5 dB.DOM (Digital Optical Monitoring) support enables proactive diagnostics—monitoring signal strength, temperature, and voltage via switch interface. This feature enhances network reliability through early detection of fiber attenuation or component degradation.

Advanced Options

Fully compatible with Aruba /HP switches when running firmware revisions that list 1990‑4116 in their supported part number (4×4) table—often firmware version 10.06.0130 or higher for CX platforms. Firmware must explicitly include this SKU to ensure correct operation.Available new or refurbished—price range varies from approximately $220 to $325 depending on condition and vendor. OEM-new units may offer extended or lifetime warranty coverage, while refurbished versions commonly carry a 90‑day warranty. Certified by HP /Aruba , this module offers dependable connectivity with consistent transmit power and sensitivity suitable for long-distance fiber links. The DOM functionality enables live monitoring of critical link parameters, helping avoid unplanned downtime by detecting degradation or contamination early.
