JL287A — Aruba 40G QSFP+ LC LR4 10km SMF xcvr

The JL287A is an HPE Aruba 40 Gbps QSFP+ transceiver for single-mode fiber, compliant with the 40GBASE-LR4 standard. Through WDM multiplexing across four wavelengths and an LC duplex connector, it delivers a 10-kilometer reach — ideal for long-distance links between network equipment.

Unlike BiDi SR modules (150 m over MMF), the JL287A covers interconnects between remote data centers or between nodes in a metropolitan network. It is designed for infrastructures equipped with SMF fiber that require stable 40G aggregation over long distances. Genuine HPE Aruba hardware, manufacturer warranty.
