Aruba 100G QSFP28 SR4 – QSFP28 SR4 Optical Transceiver

About Aruba 100G QSFP28 SR4 Optical Transceiver in Bangladesh

The Aruba 100G QSFP28 SR4 is a high-speed 100Gbps optical transceiver designed for short-reach data center and enterprise networking applications. The official Aruba product number is JL309A, identified by HPE Aruba Networking as the Aruba 100G QSFP28 MPO SR4 100m 12-fiber MPO MMF Transceiver.

Using the QSFP28 form factor and 100GBASE-SR4 optical architecture, the transceiver provides four parallel 25Gbps optical lanes using NRZ signaling for an aggregate 100Gbps Ethernet connection. It operates at an 850nm optical wavelength over multimode fiber.

The Aruba 100G SR4 uses an MPO-12 PC optical connector, with eight of the twelve available fibers used by the four optical lanes. HPE Aruba specifies a maximum transmission distance of 70 meters over OM3 fiber and 100 meters over OM4 fiber.

Aruba 100G QSFP28 SR4 Optical Transceiver Specifications & Overview

Overview

The Aruba 100G QSFP28 SR4 optical transceiver provides 100Gbps Ethernet connectivity through a compact QSFP28 interface. It is designed for high-density data center environments where reliable 100GbE connectivity is required over short multimode fiber distances.

The 100GBASE-SR4 architecture uses four parallel optical lanes, with each lane carrying 25Gbps using NRZ signaling. Together, the four lanes provide the 100Gbps aggregate data rate.

Operating at 850nm over multimode fiber, the JL309A supports up to 70 meters over OM3 and up to 100 meters over OM4 fiber. It is therefore suitable for rack-to-rack, switch-to-switch, leaf-to-spine, and other short-reach data center connections.

The module uses an MPO-12 PC optical connector. HPE Aruba specifies that the transceiver uses eight fibers within the 12-fiber MPO interface. Correct MPO polarity, connector type, fiber grade, and cabling configuration should be verified before installation.

HPE Aruba specifies Digital Optical Monitoring (DOM) support and a 3.5W required power level for the JL309A.
