D-Link 40GBase-LR4 QSFP+ Single-Mode Transceiver, 10km

The D-Link 40GBase-LR4 QSFP+ transceiver module represents a critical component for high-density, high-speed network infrastructure, specifically engineered for demanding enterprise and data center environments. This module facilitates 40 Gigabit Ethernet connectivity over extended distances, leveraging advanced optical technology to ensure robust and reliable data transmission. Its design adheres to the QSFP+ form factor, a standard recognized for its compact size and high port density, allowing network architects to maximize bandwidth within limited rack space. The 'LR4' designation signifies its suitability for Long Reach applications, utilizing four distinct wavelengths for data transmission, which is key to achieving its impressive range and capacity.

With a maximum reach of 10 kilometers over single-mode fiber, this D-Link transceiver is an ideal solution for connecting dispersed network segments, inter-building links, or backbone connections within large campus networks. The utilization of single-mode fiber optic cable is crucial for maintaining signal integrity over these extended distances, minimizing dispersion and attenuation. This makes it a cost-effective and high-performance choice compared to alternatives that might require intermediate amplification or more complex signal regeneration. Its compatibility with standard QSFP+ ports ensures broad integration capabilities with a wide array of switches, routers, and network interface cards from various manufacturers, underscoring its role as a versatile building block in modern networking architectures.
