Optical Connectivity 1 DENALI ™ Patch Cassettes DENALI Patch Cassettes enable high-density, high-performance fiber interconnects for data center and enterprise environments. Designed for seamless integration with MPO Trunk Assemblies, Patch Cords, and Fanouts, these Cassettes simplify network scaling while maximizing rack space. DENALI Patch Cassettes are fully compatible with all DENALI Housings. Front and rear adapter access supports efficient cross-connection, while the compact footprint enhances fiber management in high-density deployments. Globally available in a variety of configurations, DENALI Patch Cassettes streamline installation, reduce infrastructure complexity, and deliver consistent network performance. Features • High-Density Connectivity - Up to 12 LC ports (24 fibers) per cassette - Base-8, Base-12, Base-16, and Base-24 configurations • Designed for Seamless Integration - Front or rear cassette loading for flexible installation - Shuttered LC Adapters to improve laser safety and reduce dirt/ contamination ingress Benefits • Scalable by Design - Enables speeds from 10G to 800G and beyond - Modular form factor supports incremental or full-scale growth - Future-ready for equipment upgrades and parallel optic architectures • Optimized for Plug-and-Play Simplicity - Faster patching with shuttered adapters (LC only) and optimized finger access • Consistent Performance at Global Scale - Maintains low-loss, high-density performance across global deployments - Compatible with DENALI sliding tray system for efficient cable management Applications • AI/ML • Hyperscale • Colocation • Campus Networks • Central Office and Office Backbone Optical Performance Connector Mating Insertion Loss Average Insertion Loss Max Return Loss LC Premium Low Loss (MM) 0.08 dB 0.15 dB N/A LC Premium Low Loss (SM) 0.12 dB 0.15 dB ≤ - 60 dB 2 AFLglobal.com 1 (800) 866-7385 © 2025, AFL, all rights reserved.
