Twaron Tape is designed for optical fiber cables (OFC), which are crucial in modern communications. Traditionally, indoor cables use multiple strands of high-modulus, high-strength aramid yarn to protect the core. However, the market is evolving with demands for higher data transmission over longer distances. Twaron Tape, a patented solution by Teijin Aramid, allows for the production of cables as small as 1.2mm in diameter, offering significant space savings and increased capacity for optical distribution frames by 30-50% compared to 1.6mm cables. Additionally, thinner cables require less cooling power, reducing costs and emissions.

Twaron Tape enhances cable production speed, saving time. Cables reinforced with Twaron Tape are easier to handle, install, strip, and connect. This innovation exemplifies how Teijin Aramid adds functionality through advanced finishes.

The FTTx market (Fiber To The Home, Fiber To The Business, etc.) demands optical fiber cables that fit into smaller spaces, are strong, crush-resistant, and easy to install. Twaron Tape D2800, a slim, strong ribbon of aramid fiber, addresses these needs. It consists of a single, spread aramid yarn impregnated and fixed with a matrix material, with a typical width of 2.9mm and thickness of 100 µm, supplied on 25km flange bobbins. Its mechanical properties match those of high-modulus aramid yarn.

As optical fiber cables become smaller, protecting their core becomes challenging. Twaron Tape offers better coverage and optimal force and crush resistance, providing three to five times better crush resistance than ordinary aramid fiber protection.
