Hyperscale assemblies NAI has introduced a series of new fiber optic cable harnesses designed specifically for hyperscale computing in data centers. The cables are pre-terminated at one end with LC or MPO connectors, although customers can specify any fiber optic connector, and the harness is then spooled onto a crate reel at customer-specified lengths. The length limit is generally defined by the reel dimensions needed for safe handling and transportation. The pre-terminated end reduces field terminations and eases installation, especially in data centers where operating space is limited. Various assemblies and fiber counts are available. A pliable, single-mode ribbon cable is OFNR riser rated and suitable for high density space requirements, while a flame-retardant PVC sheath provides a rugged yet flexible cable for indoor riser applications. The UV acrylate coated fibers are color coded per TIA-359 and TIA-598. Each fiber ribbon consists of 12 primary fibers aligned in parallel. The ribbon is intermittently separated for pliability. All

ribbons are placed in a single, non-filled, flame-retardant PVC buffer tube. A cable sheath covers the buffer tube and consists of a layer of fiberglass yarns and a layer of rigid FRP strength elements.

The PVC jacket is colored yellow for single- mode designation.

The form factors of hyperscale data centers are designed to optimize performance and reduce costs. NAI has engineered its special cable assembly solutions to accommodate this application in data centers.
