Data Center
DYS high-density fiber optic cable assemblies are built for the port density of 400G, 800G and 1.6T AI data center fabrics. The range covers VSFF MMC and SN-MT assemblies, MT ferrule interconnects for transceivers and silicon photonics, LC Uniboot patch cords, pre-terminated cables with 12 to 144 fanouts, fiber array units (FAU) for chip coupling, and shuffle patch cords, flex boards and boxes that re-map optical paths across multi-plane spine-leaf networks — with fiber counts, lengths and mappings built to your drawing.

Where DYS data center assemblies are used
- AI and GPU clusters — shuffle patch cords and Shuffle Boxes spread each server's traffic across multiple switches and network planes, with the fiber mapping fixed in the factory.
- Inside 800G / 1.6T switches and CPO engines — Fiber Shuffle flex boards route up to 1,200 fibers between optical engines and front-panel ports; fiber arrays couple fiber to the photonic chip.
- Transceivers and active optical cables — MT ferrule assemblies connect QSFP, SFP+ AOCs and parallel optical modules.
- High-density structured cabling — VSFF MMC connectors deliver 3× the port density of MPO; SN-MT and LC Uniboot save space at panels and switch faceplates.
- Equipment connections — pre-terminated cables join trunk cables or transfer modules to equipment ports, 100% tested in the factory.
Choosing the right product
Match the assembly to the job:
- More ports per panel → MMC (16F or 24F) or SN-MT (16F) VSFF assemblies.
- Breakout to equipment → pre-terminated cable (12–144F, MPO / LC / SC / FC) or LC Uniboot duplex patch cords.
- Optics and photonic chips → MT assemblies (2–24F ribbon) or fiber array units in single-mode, multimode or PM fiber.
- Traffic across network planes → shuffle patch cords, a Fiber Shuffle flex board (12–1,200 fibers) or a 1U–4U Shuffle Box.
