HPE1990-4608

Aruba1000BASE-LX SFPLC Transceiver module

The HPEAruba1990-4608 is a 1000BASE-LX SFPTransceiver module engineered for single-mode fiber applications, supporting Gigabit Ethernet over distances up to 10 km. Operating at a wavelength of 1310 nm using standard NRZ encoding, this mini-GBIC module is compatible with Aruba, HPE, and ProCurve 1 Gb ports that support LX optics. With a duplex LC connector interface, it delivers reliable link performance and integrates seamlessly into access, distribution, or campus aggregation layers requiring long-reach fiber connectivity. The module supports Digital Optical Monitoring (DOM), allowing administrators to track transmit/receive optical power, temperature, and voltage for proactive link diagnostics.

Features

Designed to industry-standard SFPMSAs, the 1990-4608 module is fully supported across many Arubaand HPEswitches, including the 5400, 6100, 6200, 6300 series and more, provided correct firmware is installed. Per Arubacompatibility matrix, the supported "4×4 part numbers" include 1990-4762, 1990-4802, 1990-4891 for this LX variant × the 1990-4608 SKU is listed under these supported strings in switch software version 10.06.0130 or later on 6100/6300 platforms.The optical transmitter powers range from approximately -9.5 to -3 dBm, with receiver sensitivity of -20 to -3 dBm, offering an optical budget of around 7.5 dB×suitable for distances up to 10 km over 9/125 µm single-mode fiber. DOM support via SFF-8472 enables real-time monitoring of link health parameters such as temperature, voltage, and optical power, enhancing proactive maintenance.Available from multiple resellers×including Headset Zone, HardDiskDirect, and Compudevices×the module is sold both new and refurbished with typical price range from $215 to $275. OEM-certified versions provide full support and compatibility; third-party equivalents like JL746A (TAA compliant) are alternative SKUs with matching performance.

Advanced Options

Engineered for enterprise deployments, this Aruba/HPE-certified module delivers stable performance for single-mode link applications requiring extended distance and reliability. Its consistent optical power levels and high receiver sensitivity ensure clean, low-loss links even in challenging fiber environments.DOM capability enables network teams to monitor and alert on key link metrics such as transmit/receive power, voltage, and temperature×supporting early detection of fiber degradation or connector contamination before critical loss occurs. Hardware compatibility is guaranteed on supported platforms when paired with the appropriate Arubasoftware revision (e.g., 10.06.0130 or higher for JL746A-related support).
