TiniFiber, a U.S.-based provider of high-performance digital infrastructure solutions, has launched a new Direct Burial version of its patented Micro Armor Fiber optical cabling, engineered for enhanced durability, installation efficiency, and environmental resilience.
The newly released cable extends TiniFiber’s Micro Armor product line, which incorporates a patented steel-Kevlar® armoring technology. The latest Direct Burial (DB) variant delivers protection against moisture, rodents, chemicals, and mechanical stress while maintaining an ultra-small, ultra-light, and ultra-flexible profile. With a diameter of just 7.5 ±0.5 mm, the cable supports up to 24 fibers and is available in both single-mode and multimode configurations.
Designed to meet ANSI/ICEA S-87-640, Telcordia GR-20, and ANSI/TIA-568.3-D standards, the cable features a dry water-blocked core, rugged steel armor, and a high-density polyethylene (HDPE) outer jacket infused with UV additives, enabling use in both direct burial and aerial lashing installations.
TiniFiber emphasized that the enhanced Kevlar volume and advanced HDPE compound casing were key to maintaining protection and flexibility in a compact footprint. The combination of steel and Kevlar armoring aims to deliver higher resilience against accidental cuts, crush forces, and rodent intrusion—common risks in buried and exposed deployments.
“With the Direct Burial cable, we’re pushing the boundaries of what micro-armored fiber can do in real-world conditions,” said Tom Artinian, CEO of TiniFiber. “This product embodies our mission to offer smaller, lighter, and more durable alternatives to legacy fiber cable systems—ultimately helping our customers reduce installation costs while maximizing network uptime and throughput.”
The new cable is positioned to support deployments in data centers, municipal networks, critical infrastructure, and telecom systems exposed to harsh environmental conditions.
TiniFiber is the exclusive manufacturer of Micro Armor Fiber cabling, known for its innovation in compact armored fiber optics tailored for modern digital infrastructure needs.
