Description

Introducing the FiberTech® LD-80 Laser Cables, a pinnacle of innovation in the realm of industrial lasers. These cables are expertly designed to meet the demands of high-power laser applications, offering unparalleled performance and reliability. Each cable is crafted with precision, featuring LD-80 freestanding fiber connectors that ensure optimal laser beam delivery. The robust construction is complemented by a PVC-coated steel-armored protection tube, providing exceptional durability and protection in even the most challenging environments.

The core of the FiberTech® LD-80 Laser Cables is a copper-based high-accuracy fiber ferrule, designed for effective heat removal and high fiber centricity. This ensures that the laser beam is delivered with precision, maintaining alignment and minimizing energy loss. Suitable for laser beam delivery of up to 800 W, these cables are engineered to handle high power with ease, making them ideal for a wide range of industrial applications.

Each cable is constructed using VIS-IR all-silica (silica/silica) step-index fiber, with a numerical aperture (NA) of 0.22, ensuring excellent light transmission and minimal signal degradation. For those with specific requirements, a numerical aperture of 0.12 or graded-index fiber options are available upon request. The connectors are designed with a Ø 4 mm x 10 mm size, featuring a key for anti-twist functionality, a free-standing fiber tip, and a hex nut for secure attachment.

The FiberTech® LD-80 Laser Cables are engineered with all copper alloy parts, enhancing heat removal capabilities and ensuring long-lasting performance. With a fiber centricity of less than 5 µm from the fiber core to the ferrule, these cables offer precision and reliability in laser beam delivery. The squarelock, green PVC-coated protection tube not only provides robust protection but also adds a layer of electrical isolation from end to end, ensuring safety and efficiency in operation.

Frequently Asked Questions

What are LEONI FiberTech LD-80 laser cables and what are they used for?
FiberTech LD-80 laser cables are industrial laser delivery cables designed by LEONI Fiber Optics for safe and efficient transmission of high-power laser radiation. They use VIS-IR all‑silica step‑index fibers with numerical aperture (NA) 0.22 and are suitable for average laser powers up to 800 W. Typical applications include industrial material processing, welding, cutting, marking, and general high‑power laser beam delivery where robust, flexible, and thermally stable fiber cables are required.
What core sizes and standard cable lengths are available for the LD-80 laser cables?
The FiberTech LD-80 series is offered with fiber core diameters of 100 µm, 200 µm, 400 µm, 600 µm, 800 µm, and 1000 µm. Standard catalog cable lengths are 2 m, 3 m, and 5 m, each with corresponding part numbers (e.g., FCL30-10200-2000, FCL30-10300-2000, FCL30-10500-2000 for 100 µm core at 2 m, 3 m, and 5 m). Other lengths are often available on request from LEONI or distributors, provided the optical and thermal limits remain within specification.
What is the maximum laser power and wavelength range supported by FiberTech LD-80 cables?
FiberTech LD-80 laser cables are specified for average laser powers up to 800 W in continuous operation, assuming proper cooling and system integration. They use VIS-IR all‑silica (silica core/silica cladding) step‑index fibers, meaning they cover the visible to infrared wavelength range commonly used by industrial solid‑state, fiber, and diode lasers (e.g., around 808 nm, 940 nm, 980 nm, 1030–1080 nm, and similar). For operation very close to power or wavelength limits, LEONI or your laser manufacturer should confirm compatibility with your specific laser model.
What connector type and protection tube do LD-80 laser cables use?
These cables are equipped with LD-80 freestanding fiber connectors featuring 4 mm × 10 mm bodies with a keyed anti‑twist design and a hex nut for secure mounting. The fiber tip is free‑standing for efficient beam delivery. The protective jacketing is a squarelock steel‑armored tube with a green PVC coating, providing mechanical robustness, abrasion resistance, and flexibility. Metal connector cuffs provide a secure mechanical interface to the armored tube while maintaining full electrical isolation from end to end.
How do LD-80 laser cables manage heat and maintain beam quality?
LD-80 laser cables use copper‑based high‑accuracy fiber ferrules and all copper alloy connector parts to enable efficient heat removal from the fiber end faces, which is critical at powers up to 800 W. Fiber centricity is specified to be < 5 µm from fiber core to ferrule, ensuring precise alignment, low coupling losses, and stable beam quality. This makes them comparable to other high‑power industrial laser delivery cables used with fiber and solid‑state lasers, where thermal management and alignment accuracy directly affect lifetime and performance.
What numerical aperture (NA) options are available and can I request different fiber types?
The standard FiberTech LD-80 cables use a VIS‑IR all‑silica step‑index fiber with NA = 0.22, which is typical for many industrial laser delivery applications. An NA of 0.12 is available on request for systems that require a lower divergence, and graded‑index (GI) fiber versions are also available upon request. When ordering, you can specify the desired NA and fiber type so the cable will match your laser’s output optics and your beam quality requirements.
In which industrial environments are FiberTech LD-80 cables typically used?
Due to their steel‑armored, PVC‑coated protection tube and high‑power handling capability, FiberTech LD-80 cables are suited to harsh industrial environments such as automated production lines, robot‑guided laser workstations, cutting and welding cells, and general machine tool integration. The squarelock armor provides crush and bend protection, while electrical isolation from end to end supports safe integration into systems where grounding and electrical separation are important. Always respect the minimum bend radius and mounting recommendations provided by LEONI to ensure long service life.
