HPE JL780A 

Aruba 1 Gb Ethernet SFP LC SX Transceiver module

The HPE Aruba JL780A is an industrial-temperature small form-factor pluggable (SFP ) Transceiver module  designed for Gigabit Ethernet over multimode fiber. Operating at 850 nm using the 1000BASE‑SX standard, it supports single-lane speeds up to 1.25 Gbps, compatible with 1 Gb/s Ethernet and Fibre Channel lines. Certified for rugged environments, it can operate reliably from –40 °C to +85 °C, making it suitable for outdoor or industrial deployments. With an LC duplex connector and reach up to 500 m over OM2 fiber (or 550 m on OM4), it's a dependable choice for campus backbone links, switch uplinks, or access point backhaul. Integrated Digital Optical Monitoring (DOM) allows real‑time diagnostics of optical power, temperature, and voltage via SFF‑8472 protocol, supporting preventive maintenance and link integrity monitoring.

Features

This Transceiver module conforms to industry-standard SFP MSA specifications and is fully OEM-certified for HPE and Aruba networking equipment. It delivers reliable short-reach fiber connectivity, ideal for linking switches, access points, or servers across structured cable installations in enterprise and industrial networks . The module supports a 7.5 dB optical budget, with transmit power ranging from –9.5 dBm to 0 dBm and receiver sensitivity around –17 dBm, ensuring clean signal integrity up to 500 m over multimode fiber Certified for use with Aruba CX 6000, 6100, 6300, 6400 series switches and various Aruba AP models, support includes industrial-temperature variants to handle extreme ambient conditions . When deployed in critical environments, its DOM support via I²C allows administrators to monitor link status, optical performance metrics, and preemptively detect degradations. The module is plug-and-play with automatic identification by compatible platforms, simplifying deployment. Its rugged design—with operating range from –40 °C to +85 °C—makes it well-suited for outdoor wireless backhaul, manufacturing floor cabling, or unheated telecom closets

Advanced Options

Built to withstand industrial temperature extremes, this module ensures stable performance in harsh conditions without sacrificing signal integrity. The optical budget (~7.5 dB) and sensitivity specs support reliable fiber links over 500 m, with transceiver performance tolerant of moderate fiber impairments OEM validation with HPE /Aruba networking gear ensures compatibility and full support for fleet management features such as Sharp firmware updates, configuration consistency, and device interoperability—even in mixed-vendor environments. DOM diagnostics enable real-time monitoring of link parameters, helping identify issues like fiber bend loss or connector contamination before service disruption occurs.
