Bridge the AI Fiber Explosion

GPX13 Ultra-High-Density Splice Panel — Bring up to 576 outdoor armored fibers into your data center with managed, low-risk maintenance access.

The 4RU solution for campus interconnects that pre-terminated cables can't touch.

576 Fibers

4RU Height

1.5m Service Reach

576 Fibers in 4RU

As AI clusters push fiber counts higher, GPX13 delivers 144 fibers per rack unit, enabling ultra-high-density outdoor-to-indoor handoff without wasting rack space. Built to scale with campus, POP, and DCI fiber growth.

Low-Risk Maintenance at the Splicing Table

The integrated tray extends up to 1.5 m to a dedicated splicing table, avoiding cramped in-rack work. Its coiled service loop keeps signal deviation below 0.2 dB during movement, enabling maintenance or expansion without disrupting active AI workloads.

Flexibility for Brownfield and Greenfield

One chassis, two architectures: GPX13-Single (576F, book-style cassettes) for precise single-fiber re-splicing in brownfield networks, or GPX13-Ribbon (288F, flat cassettes) for fast rollout of high-count ribbon cables in greenfield AI backbones.

Built for OSP Reality

Built for the trench-to-rack transition, GPX13 secures armored outdoor cables with dedicated strain relief and guided routing, then cleanly splices to SC/LC pigtails with <0.15 dB typical loss—rugged outside, precision inside.

Deployment Configurations

Training Clusters That Span Buildings

Your AI workload doesn’t fit in one building. The GPX13 bridges the fiber gap between compute halls—handling the massive spine fiber counts (288-576 fibers) needed for GPU-to-GPU communication across campus. Outdoor armored cable survives the trench between buildings; the GPX13 brings it into your indoor patching infrastructure at ultra-high density, leaving rack space for the compute that matters.

Meet-Me Room Density

Connecting to cloud gateways, IXPs, or DCI nodes requires high-fiber-count handoffs from outdoor carrier cables. In meet-me rooms where SC connectors still dominate for their consistent 2.5mm performance, the GPX13-SC configuration manages 288 fibers in 4RU—terminating carrier armored cables cleanly and leaving room for cross-connect growth. No pre-term solutions that violate OSP specifications.

Evolve Without Replacing

Your existing campus has legacy single-fiber cables, but your new AI wing needs ribbon efficiency. Deploy GPX13-Single cassettes for the existing plant re-splicing, and GPX13-Ribbon cassettes for the new high-count backbone—all in the same 4RU chassis. The 1.5m service reach means you can add the new fibers to the same tray without disturbing the existing live links you’re migrating.
