HPE Aruba 200G SR4 QSFP56 – QSFP56 SR4 Optical Transceiver

About HPE Aruba 200G SR4 QSFP56 Optical Transceiver in Bangladesh

The HPE Aruba Networking 200G SR4 QSFP56 MPO12 100m MMF Transceiver is a high-speed 200Gbps optical transceiver designed for high-density data center and enterprise networking environments. The official HPE product number is S4B43A.

Using the QSFP56 form factor and 200G SR4 optical architecture, the transceiver provides four parallel 50Gbps PAM4 optical lanes for an aggregate data rate of 200Gbps. It operates at an 850nm optical wavelength over multimode fiber and uses an MPO-12 UPC optical connector.

The HPE Aruba 200G SR4 is designed for short-reach data center connectivity. HPE specifies a maximum distance of 70 meters over OM3 multimode fiber and 100 meters over OM4 or OM5 fiber, making it suitable for switch-to-switch, rack-to-rack, leaf-spine, and other high-bandwidth short-distance network connections.

HPE Aruba 200G SR4 QSFP56 Optical Transceiver Specifications & Overview

Overview

The HPE Aruba 200G SR4 QSFP56 transceiver provides 200Gbps optical Ethernet connectivity through a compact QSFP56 interface. It is designed for high-density networking environments where substantial bandwidth is required over short multimode fiber links.

The 200G SR4 architecture uses four parallel optical lanes, with each lane carrying 50Gbps using PAM4 modulation. Together, the four lanes deliver an aggregate 200Gbps optical connection.

Operating at 850nm over multimode fiber, the transceiver supports up to 70 meters over OM3 fiber and up to 100 meters over OM4 or OM5 fiber according to HPE Aruba Networking specifications. This makes it suitable for short-reach data center links where single-mode fiber is not required.

The module uses an MPO-12 UPC optical connector. Correct connector type, fiber polarity, lane mapping, and multimode fiber grade must be verified before deployment.

HPE specifies Digital Optical Monitoring (DOM) for the S4B43A, allowing supported networking equipment to monitor optical operating parameters. The specified power requirement is 10W.
