HPE JW091A 

Aruba 10GBase-SR SFP+ transceiver module

The HPE Aruba JW091A is a high-performance 10GBase-SR SFP+ transceiver module engineered for short-reach, high-bandwidth optical connectivity in modern networks. Designed for enterprise and data center environments, it seamlessly integrates with Aruba switches and compatible SFP+slots to deliver reliable 10 Gigabit Ethernet connectivity over multimode fiber. Operating at an 850 nm wavelength, this module supports transmission distances of up to 300 meters over OM3 fiber (and up to 400 m over OM4), making it ideal for rack-to-rack, switch-to-switch links. Its SFP+ compact form factor, hot-pluggability, and adherence to industry standards such asSFP+ MSA and SFF-8432 ensure easy deployment and interoperability. With digital optical monitoring (DOM) support, network administrators gain real-time insight into operational parameters—bolstering manageability and enabling proactive diagnostics. JW091A fulfils demanding network performance needs with a blend of speed, compatibility, and ease of use.

Features

In modern IT environments—such as data centers, campus networks, and enterprise backbones—the demand for scalable, high-speed interconnects is critical. The JW091A placeholder fits seamlessly into this ecosystem by offering 10 Gigabit Ethernet links via SFP+slots. Once inserted, it automatically negotiates with the host device and establishes a robust optical connection—eliminating manual configuration hurdles. Its duplex LC interface supports multimode fiber infrastructure, enabling flexible topology design across network closets, aggregation layers, or edge switches.Beyond basic connectivity, JW091A’s compliance with SFP+ Multi-Source Agreement (MSA) specifications ensures compatibility across various vendor platforms. This is especially valuable in heterogeneous setups using Aruba , Cisco, NetApp, Supermicro, and other hardware. With DOM capabilities (as supported in compatible versions), the module provides crucial metrics like optical power and temperature—empowering IT teams to monitor the health of fiber links in real-time. The module’s hot-swappability also means you can insert or remove it without shutting down the system, minimizing downtime during maintenance or upgrades. Technical robustness, adherence to safety standards, and ease-of-use combine to make this transceiver a reliable backbone component in demanding network infrastructures.

Advanced Options

The JW091A module is built for long-term reliability in diverse operating conditions. Its robust metal housing and VCSEL/PIN photodiode optics provide consistent performance while minimizing EMI interference. With an operating temperature range of 0 °C to 70 °C, this transceiver suits standard data center environments—and industrial-grade variants may extend this further
