9N51Y DELL 100GbE QSFP28 10km LR4 LC SMF Gen 3 Transceiver

9N51Y Overview

The is a Dell 100GbE QSFP28 LR4 optical transceiver designed for long-range data transmission over single-mode fiber. It operates using the 100GBASE-LR4 standard, employing four LAN-WDM wavelengths around 1310nm to deliver high-speed connectivity over extended distances.With support for distances up to 10 kilometers over SMF, this module is ideal for inter-building connections, campus networks, and long-distance data center interconnects.The transceiver uses wavelength-division multiplexing (WDM) to combine four 25Gbps optical lanes into a single duplex LC fiber pair, ensuring efficient fiber utilization and reliable high-bandwidth performance.
