Optical Connectivity 1 DENALI ™ Splice Cassettes DENALI Splice Cassettes deliver flexible, high-density splice management for evolving data center and enterprise networks. Designed for rapid field termination, each cassette supports 250-micron single fiber or ribbon pigtails. A snap-in splice sleeve cradle keeps both single and ribbon fibers neatly organized, and the cassette design allows front or rear installation for efficient Moves, Adds, and Changes (MACs) without disrupting adjacent connections. Globally available, DENALI Splice Cassettes simplify splicing, reduce installation time and maintain consistent network performance. Features • High-Density Splicing - Up to 12 LC ports (24 fibers) per cassette - Supports Base-12, Base-16 and Base-24 configurations • Seamless Integration - Pre-loaded and pre-routed pigtails - Single fiber or ribbon fiber splicing - 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 • Consistent Performance at Global Scale - Maintains low-loss, high-density performance across global deployments - Compatible with DENALI’s sliding tray system for efficient cable management • Fast, One-Person Installation - Faster patching with shuttered adapter - Splice work can take place conveniently away from the rack - 60-75% faster field splicing with ribbon pigtails and mass-fusion splicing 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.

Part of the Denali™ platform, Splice Cassettes include 250 micron preterminated single fiber pigtails (or one bare ribbon pigtail), that are loaded within the cassette and can be spliced directly to loose (or ribbon) fiber cable.

All Splice Cassettes feature VFL-compatible shuttered LC adapters with up to 12-fiber capacity. Available in single-mode and multimode fiber types, cassettes leverage a snap-in splice sleeve cradle to securely manage both single and ribbon fiber arrangements.

Splice Cassettes are compatible with all BASE-12 DENALI housings and can be independently installed easily from the front or rear onto a sliding tray system. This allows access to individual connections while minimizing disruption to other fiber connections.
