The HPE JL485A (also known as the Aruba 25G SFP28 LC eSR transceiver) is a hot-pluggable 25 Gb/s module crafted for short-reach multimode fiber networks. Adhering to the 25GBASE-ESR Ethernet standard, it utilizes an 850 nm VCSEL over empirical duplex LC connectors and supports up to 300 m on OM3 and 400 m on OM4 multimode fiber. The transceiver supports bidirectional 25.78 Gb/s links, operates on a single 3.3 V supply with under 1 W power consumption, and includes integrated Digital Optical Monitoring (DOM) for real-time diagnostics. Rated for commercial environments (0 °C to 70 °C), it’s designed for seamless compatibility with HPE Aruba switches and typically carries a lifetime warranty through third-party vendors.
