Dell QSFP-40G-SR4 – QSFP+ SR4 Optical Transceiver

About Dell QSFP-40G-SR4 QSFP+ SR4 Optical Transceiver in Bangladesh

The Dell QSFP-40G-SR4 is a high-speed 40Gbps Ethernet optical transceiver designed for short-reach fiber connectivity in data centers, enterprise networks, and high-performance networking environments. Using the QSFP+ form factor and 40GBASE-SR4 parallel optical technology, it provides reliable 40GbE connectivity over multimode fiber.

The transceiver uses four parallel optical lanes, each carrying approximately 10Gbps, to provide an aggregate 40Gbps Ethernet connection. Operating at an 850nm optical wavelength, the module is designed for short-distance multimode fiber links between compatible switches, routers, servers, and other 40GbE networking equipment.

The Dell QSFP-40G-SR4 uses a parallel MPO-12 optical interface and is suitable for high-density switch-to-switch connections, server uplinks, spine-leaf networking, data center aggregation, and other short-reach 40GbE applications. Actual link distance depends on fiber grade, optical budget, cabling, connectors, and connected equipment.

Dell QSFP-40G-SR4 QSFP+ SR4 Optical Transceiver Specifications & Overview

Overview

The Dell QSFP-40G-SR4 provides 40Gbps optical Ethernet connectivity through the compact QSFP+ form factor. It is designed for data center and enterprise networks that require high-speed connectivity over short multimode fiber distances.

The 40GBASE-SR4 architecture uses four parallel optical lanes, each operating at approximately 10Gbps, to deliver a total 40Gbps connection. Its 850nm multimode optical design makes it suitable for short-reach network links where high bandwidth and efficient port density are important.

With compatible OM3 multimode fiber, the module can typically support distances up to approximately 100 meters, while OM4 fiber can extend the link to approximately 150 meters under suitable conditions.

The parallel optical design uses an MPO-12 interface and requires compatible fiber cabling with correct polarity and lane mapping. Proper selection of MPO cabling is essential for reliable operation.
