Demands for connectivity in the data center are rising, especially in hyperscale data centers where 1728- or 3456-fiber cables are becoming more popular. Connecting such high-fiber-count cables to servers and switches is the key challenge because there's only so much rack space available. Fiber patch panels are at the center of this challenge. To address this issue, the industry is increasing port density in patch panels to accommodate the ongoing thirst for bandwidth.
