Build 10 GbE links that stay consistent across your multimode fiber plant. The HPE Aruba JL748A SFP+ transceiver is built for short-reach optical connectivity over LC duplex MMF, with support for up to 300 m. It fits naturally into access and aggregation layers, as well as server uplinks, where teams need a compact optic that keeps port density high and cabling straightforward. For organizations standardizing on Aruba switching, this module offers a clean way to extend 10 Gigabit Ethernet without changing the physical fiber infrastructure. The SFP+ form factor supports dense switch designs, while the 10 Gbps data rate is well suited to virtualization hosts, storage traffic, and high-throughput user segments. It is a practical upgrade path when you want predictable performance and a familiar optical footprint. Choose the JL748A when you need a hardware-matched transceiver that aligns with enterprise deployment standards and preserves the value of installed MMF. It is the kind of component that earns its place in networks where uptime, compatibility, and cable plant efficiency matter.
