LINDEN-SPE-7090 STFOC 500um is a slim, lightweight, singlemode Strong Tether Fiber Optic Cable designed for applications where small diameter, flexibility, strength, and reliable optical performance are important. With a compact 0.500 mm / 0.020 inch outside diameter, this cable is suitable for precision tethering, compact fiber deployment systems, underwater communication links, sensing systems, and other demanding environments where a standard fiber cable may be too bulky or fragile.
The cable uses Linden’s proprietary jacket design with LCP primary strength coating, giving it improved mechanical durability while maintaining a very small profile. It is designed to deliver stable singlemode optical transmission at common telecom wavelengths, with attenuation values of less than 0.45 dB/km at 1310 nm and less than 0.35 dB/km at 1550 nm.
Product Overview
The LINDEN-SPE-7090 STFOC 500um cable is built for projects that need a strong but extremely thin fiber optic tether. Its 500 micron diameter makes it well suited for compact systems where cable size, weight, and payout behavior matter. Unlike conventional ruggedized fiber cables that can be too large for miniature systems, this STFOC cable provides a practical balance between fiber protection, tensile strength, and flexibility.
This cable is especially useful where a fiber must be deployed, pulled, wound, or routed through limited space while still maintaining dependable optical performance. The singlemode fiber construction supports long-distance, low-loss data transmission for communications, sensing, and control applications.
