HPE JL309A - 100 Gb QSFP28 MPO SR4 Multimode Fiber Transceiver
The HPE JL309A is a 100 Gigabit-Ethernet QSFP28 optical transceiver built for high-density, short-reach multimode-fiber links×typically between switches, aggregation to core in data-centers or campus backbones. If you're running a 100 G capable switch and need a reliable link over multimode fiber, this module provides up to 100 m reach on OM4 or around 70 m on OM3 fiber. It uses the SR4 (4-lane of 25 Gb) approach over a 12-fibre MPO connector and supports digital optical monitoring (DOM). It suits deployments where you want 100 Gb links without committing to single-mode or long-haul optics.
Key Features
100 Gbps aggregate data rate (4×25 Gb) in a QSFP28 form factor for high-capacity interconnects.
MPO-12 connector with SR4 multimode fiber support×up to ~100 m on OM4 and ~70 m on OM3 fiber.
Digital optical monitoring (DOM) capability for real-time performance and diagnostics.
Low power consumption (~3.5 W typical) reduces thermal load in dense switch setups.
Compatible with HPE/Aruba switches that support QSFP28 SR4 optics, enabling seamless integrations in enterprise data-centres and campus fabrics.
