About Aruba JL484A 25GBASE-SR SFP28 Optical Transceiver in Bangladesh
The Aruba JL484A is a 25Gbps SFP28 optical transceiver designed for short-reach Ethernet connectivity over multimode fiber. HPE Aruba identifies JL484A as the Aruba 25G SFP28 LC SR 100m MMF Transceiver.
The module uses a single 25Gbps NRZ optical lane operating at 850nm. It is designed for 50/125µm multimode fiber and uses a duplex LC optical connector, providing a compact and cost-effective solution for high-speed data center and enterprise network connections.
HPE Aruba specifies a transmission distance of up to 70 meters over OM3 fiber and up to 100 meters over OM4 fiber. This makes JL484A suitable for rack-to-rack, switch-to-switch, leaf-to-spine, server-to-switch, and other short-distance 25GbE connections.

Overview
The Aruba JL484A 25GBASE-SR SFP28 optical transceiver provides 25Gbps Ethernet connectivity through a compact SFP28 interface. It is designed for high-density networking environments requiring short-reach optical connections over multimode fiber.
The SR architecture uses a single 25Gbps NRZ optical lane at 850nm. The module connects to the network through duplex LC fiber and is optimized for OM3 and OM4 multimode infrastructure.
With a specified reach of 70 meters over OM3 and 100 meters over OM4, JL484A is well suited to data center rack-to-rack links, server-to-switch connectivity, top-of-rack deployments, and short-distance switch interconnections.
HPE Aruba specifies 50/125µm multimode fiber with 2000 MHz·km modal bandwidth for OM3 and 4700 MHz·km for OM4. The transceiver is not intended for OM1 or OM2 multimode fiber because 25G SR/eSR operation is not supported over those fiber grades.
The module uses duplex LC connectivity and supports PC or UPC connector polish. HPE Aruba specifies a 1.2W power requirement and commercial operating temperature from 0°C to 70°C.
