Days vs. Weeks
Fúxī (Monolithic): Factory-cabled, scheduled production
Fúxī (Monolithic): Factory-cabled, scheduled production, maximum density. Standard counts (288/576/864F), several-week lead time, permanent infrastructure. Longma (Braided): Semi-automated braiding over sub-units, days-not-weeks delivery. Any fiber count (144F–864F+), field-modifiable, experimental topologies. Both share identical fiber specs and assemblies —performance parity, logistics flexibility. Whether you need certified plant precision or crisis-response agility, the same optical excellence applies.
3x Density with SN-MT & MMC
While competitors are still ramping, ADTEK has VSFF (Very Small Form Factor) assemblies in stock today. SN-MT and MMC provide triple the port density per rack unit versus legacy MPO/LC—critical for 800G and emerging 1.6T architectures. Paired with our ultra-slim 1.6mm fan-out legs, VSFF enables true high-density spine-leaf without the assemblies bottleneck. Available for both Fúxī and Longma series.
Pristine End-Faces After the Blow
AI switches are thermal choke points. Our 1.6mm VSFF fan-out legs reduce cross-sectional obstruction by 71.5% versus legacy 3.0mm cables based on geometric calculation—enabling improved laminar airflow through 1RU switch exhaust paths. The theoretical advantage is clear: 36 cables occupying just 72.4 mm² versus 254.5 mm² for traditional cabling. Less obstruction, lower fan power, reduced cooling OPEX. Designed for thermal optimization, engineered for AI density.
Custom Super-Trunks to 6,912F
Standard portfolio covers 288F–864F. Beyond that, our engineering team designs custom Super-Trunks—aggregating multiple 864F rollable ribbon sub-units into managed pathways of 3,456F or 6,912F. We’ve validated the assemblies processes and trained our design engineers for extreme density. Available as custom capability upon request for next-generation AI core backbones where standard products don’t exist. Note: Currently evaluating cable producers for 3,456F/6,912F; design and termination capability confirmed.

Deployment Configurations
Scheduled Precision for Maximum Density
New hyperscale data center, 10,000+ GPU cluster, scheduled build-out. Fúxī delivers maximum density with 17.0mm OD for 864F—smaller than competitors’ 576F offerings. Factory-terminated precision ensures consistent insertion loss for permanent infrastructure. VSFF SN-MT assemblies enable 800G DR8/1.6T spine-leaf architectures without patch panel congestion. Order 6-8 weeks ahead of installation window for coordinated delivery.
Supply Chain Agility in Days
Competitor lead times slipped, cluster expansion delayed, need 576F in days not weeks. Longma’s semi-automated braiding process uses pre-stocked sub-units assembled to order. No MOQ means you can order exactly 432F (not forced into 576F standard). Field-modifiable architecture allows mixed fiber types (SMF-28 + BendBright) in the same assembly. When “time-to-light” matters more than absolute minimum OD, Longma delivers.
Asymmetric Breakouts & Super-Trunks
Research lab testing new spine-leaf variant, need 432F with asymmetric fan-out (288F to Zone A, 144F to Zone B). Or hyperscale backbone requiring 6,912F custom Super-Trunk aggregation. Longma accommodates custom fiber counts, mixed assemblies types on same trunk, and multi-sub-unit aggregation. For extreme density, our engineering team designs 3,456F and 6,912F Super-Trunks using validated assemblies processes—available as custom capability upon request.
