Product Description
The Dell QSFP28-100G-PSM4-IR is a high-density, high-performance transceiver module designed for 100 Gigabit Ethernet networks. It utilizes the QSFP28 form factor, which is standard for 100GbE interfaces, enabling high bandwidth in a compact module. This transceiver supports the 100GBase-PSM4 standard, which employs parallel single-mode fiber optics. PSM4 uses multiple single-mode fibers (typically 8 fibers for transmit and 8 for receive, totaling 16, but the MPO connector is often 12-fiber for specific configurations) to achieve its high data rate over distances up to 500 meters. This makes it ideal for short-reach, high-bandwidth links within data centers, such as switch-to-switch or switch-to-server connections. The module operates at a wavelength of 1310nm and requires a 12-fiber MPO connector for its optical interface. The use of single-mode fiber provides excellent signal integrity and lower dispersion compared to multi-mode fiber over these distances. The QSFP28-100G-PSM4-IR is a key component for building high-performance data center fabrics and backbone networks.
