Which cable design is used for small size cables with many fibers laid into rows?

• A. Loose Tube
• B. Tight Buffer
• C. Ribbons
• D. Microcable

Answer: (C)

Maximizing fiber density in a compact cable is achieved by using flat ribbons where many fibers are arranged in a single plane. When a cable needs a large number of fibers but keeps a small diameter, the ribbon design packs fibers efficiently in rows, making it easier to handle, splice, and terminate. The fibers are built into flat, flexible ribbons that can be stacked or aligned in connectors, which helps achieve high fiber counts without a bulky round cross-section. Other designs organize fibers differently and don’t emphasize row-based packing. Loose tube places fibers loosely inside gel-filled tubes, prioritizing protection and environmental sealing over dense row alignment. Tight buffer surrounds each fiber individually in a protective layer, but without forming a flat, multi-fiber row structure. Microcables focus on small overall diameter, often with fewer fibers, and don’t inherently optimize for many fibers laid in rows.
