Dell Q28-100G-SR4 – QSFP28 SR4 Optical Transceiver

About Dell Q28-100G-SR4 QSFP28 SR4 Optical Transceiver in Bangladesh

The Dell Q28-100G-SR4 is a high-speed 100Gbps optical transceiver designed for short-reach Ethernet connectivity in modern data center and enterprise networking environments. Using the compact QSFP28 form factor and 100GBASE-SR4 parallel optical technology, it provides high-bandwidth connectivity over multimode fiber.

The Dell Q28-100G-SR4 uses four parallel optical lanes to provide an aggregate 100Gbps Ethernet connection. Operating around the 850nm optical wavelength over multimode fiber, it is designed for short-distance connections such as switch-to-switch, spine-to-leaf, server uplinks, and data center interconnects.

The transceiver uses a parallel-fiber MPO interface and is suitable for compatible Dell 100GbE switches, routers, network adapters, and other networking platforms supporting QSFP28 SR4 optics. Actual reach depends on the multimode fiber grade, optical budget, cabling, connected equipment, and installation conditions.

Dell Q28-100G-SR4 QSFP28 SR4 Optical Transceiver Specifications & Overview

Overview

The Dell Q28-100G-SR4 delivers 100Gbps optical Ethernet connectivity through a high-density QSFP28 interface. It is designed for data center networks that require high bandwidth, efficient switch-port density, and reliable short-distance fiber connectivity.

The 100GBASE-SR4 architecture uses four parallel optical lanes, each providing approximately 25Gbps, for an aggregate 100Gbps connection. The 850nm multimode optical design makes the module particularly suitable for short-reach data center links.

With compatible OM3 multimode fiber, the link can typically reach up to approximately 70 meters, while OM4 fiber can provide up to approximately 100 meters under suitable conditions. This makes the Q28-100G-SR4 suitable for rack-to-rack, top-of-rack to aggregation, and spine-leaf connections.

The parallel optical interface requires compatible MPO fiber cabling with correct polarity and lane mapping. Proper cabling selection is therefore important for successful deployment.
