Fiber Optics Built for the Real World
When performance, precision, and durability matter, stock cables just don’t cut it. That’s why engineers across industries choose Cables Unlimited for custom fiber optic cable assemblies—built to exacting specifications, tested for rugged environments, and backed by over 30 years of manufacturing expertise.
Whether you’re prototyping a high-frequency system or installing backbone infrastructure, we help bring your vision to life—fiber by fiber.
Why Custom? Why Cables Unlimited?
Our clients don’t compromise. From mission-critical data transmission to fiber networks that must endure vibration, moisture, and EMI, they need engineered assemblies—not improvised ones.
Here’s why teams trust us:
-
Tailored to Application – Every cable is designed for its end-use environment, whether that’s a medical device, tactical radio, or robotic sensor.
-
Fiber Type Matching – We support OM1–OM5 multimode, OS1/OS2 singlemode, bend-insensitive, polarization-maintaining, and more.
-
Connector Precision – Terminated to spec with LC, SC, FC, MTP/MPO, TFOCA, ST, and hybrid/military connectors.
Engineered for Performance
We don’t just build fiber optic cables—we engineer them for real-world demands:
- Low Insertion Loss – Polished endfaces and matched components to minimize optical degradation
- Environmental Resistance – Outdoor-rated jackets, armored construction, and sealed terminations
- EMI Protection – Hybrid copper/fiber shielding options for mixed-signal applications
- High-Flex & Tension Strength – For robotics, manufacturing, and high-cycle motion systems
Every cable is tested in our facility before it leaves the floor, ensuring reliable field performance.
