Factory Specifications for Ribbon Optical Cables

Ribbon optical cables are high-density fiber optic cables designed for mass-fusion splicing, offering fiber counts from 4 up to 6,912 fibers in compact, flat or flexible ribbon formats.

Key Features and Specifications

Ribbon fiber design: Ribbon cables organize multiple optical fibers in a flat, matrix-style ribbon, typically containing 4, 6, 8, or 12 fibers per ribbon. This configuration allows mass-fusion splicing, where all fibers in a ribbon can be spliced simultaneously, significantly reducing installation time and labor costs compared to traditional stranded loose-tube cables. Fiber counts and density: Ribbon cables support a wide range of fiber counts.

Standard offerings include up to 288 fibers in outdoor cables, while advanced technologies like Sumitomo's Freeform Ribbon® and Prysmian's FlexRibbon® can reach 6,912 fibers in a single cable. The compact design reduces cable diameter by up to 60% and optimizes duct space. Fiber types and standards: Ribbon cables can use single-mode fibers such as G.

652. D, G. 657.

A1, or G. 657. A2, with color coding following TIA/EIA-598 or YD/T standards.

Color sequences can be customized for high fiber counts. Construction and durability: Ribbon cables are available in outdoor, indoor, plenum-rated, air-blown, and armored designs. They are lightweight, durable, and often gel-free, which simplifies splicing and reduces maintenance.

Indoor plenum cables feature flame-retardant jackets and flexible dielectric members for easy installation in space-constrained areas.
