HPE Networking X140 40G QSFP+ LC LR4L 2km SM Transceiver

The HPE JL286A is a 40 Gigabit Ethernet transceiver that lets you move large amounts of data quickly without overcomplicating your network. Designed for QSFP+ slots and built around LC connectors, it slips into compatible HPE switches or routers and is ready to carry traffic over single mode fiber up to 2 kilometers. If you are linking aggregation switches to the core, creating short inter-building runs on a campus, or giving your server cluster a faster backbone, this module delivers the bandwidth you need while keeping installation straightforward.

Because it speaks the same language as HPE Networking Comware devices, the transceiver integrates smoothly with existing management tools and firmware. The hot-pluggable design means you can add or replace it without shutting down critical equipment, a practical advantage when uptime is essential.

The module’s compact housing measures 12.45 x 22.61 x 6.35 centimeters and weighs just 0.18 kilograms, so it fits neatly into dense switch line cards or high-port-count environments. Once in place, it runs at full 40 Gb speeds with no extra configuration beyond standard optical settings, making it a dependable choice for data center teams that need performance and simplicity in equal measure.
