Frequently Asked Questions

What are FiberTech CuSMA laser cables and what are they used for?
FiberTech CuSMA laser cables are industrial laser delivery cables from LEONI featuring F‑SMA (SMA905) freestanding fiber connectors and a PVC‑coated, steel‑armored protection tube. They use VIS‑IR all‑silica step‑index fibers (NA = 0.22) and are designed for reliable laser beam delivery up to 400 W average power. Typical applications include material processing (cutting, welding, marking), laboratory laser delivery, and integration into industrial laser systems where robust, flexible fiber delivery is required.
Which fiber core diameters and standard cable lengths are available for the CuSMA laser cables?
Standard CuSMA laser cables are available with fiber core diameters of 100 µm, 200 µm, 400 µm, 600 µm, 800 µm, and 1000 µm. The datasheet lists typical cable lengths of 2 m, 3 m, and 5 m (for example: CLS0100IR08/08.0bl23/23‑0200cm100 for 2 m, ‑0300cm100 for 3 m, and ‑0500cm100 for 5 m). Other lengths are usually available on request, similar to comparable industrial SMA905 fiber cables offered on FindLight and by other laser fiber manufacturers.
What is the maximum average laser power these CuSMA fiber cables can handle?
FiberTech CuSMA laser cables are specified for average laser powers up to 400 W. This rating assumes correct connector handling, proper cooling and cleanliness, and operation within the fiber’s numerical aperture. For powers close to 400 W, many integrators choose larger core diameters (e.g., 600–1000 µm) to reduce power density at the fiber input, consistent with common practice for high‑power SMA905 delivery fibers listed on FindLight.
Which wavelengths and fiber types are supported by these CuSMA laser cables?
The CuSMA cables use VIS‑IR all‑silica (silica core/silica cladding) fibers, suitable for visible to near‑infrared wavelengths typically in the 400–2200 nm range, covering common industrial laser lines such as 532 nm, 808–980 nm, and 1 µm class fiber and diode lasers. The standard design is a step‑index fiber with NA = 0.22. On request, versions with NA = 0.12 or graded‑index fibers are available, as is typical for high‑quality SMA905 laser delivery fibers used in industrial and research environments.
What are the key mechanical and thermal advantages of the CuSMA design?
CuSMA laser cables combine several features optimized for industrial use: (1) Copper‑based, high‑accuracy fiber ferrules provide effective heat removal from the connector, improving reliability at high power; (2) Fiber centricity better than 5 µm (core to ferrule) ensures precise beam alignment at the SMA905 interface; (3) A squarelock, blue PVC‑coated steel‑armored protection tube offers high crush and bend resistance similar to other armored high‑power laser cables on the market; (4) Metal connector cuffs and end‑to‑end electrical isolation enhance mechanical stability and safety when integrating the cable into machines and laser systems.
What connector types are used and are keyed SMA905 options available?
Standard FiberTech CuSMA cables are supplied with SMA905 (also called F‑SMA) connectors featuring freestanding fiber tips and hex nuts. This is the de‑facto standard connector for many industrial and research laser delivery fibers and is widely compatible with laser sources and collimator heads found on FindLight and from other vendors. On request, keyed SMA905 (F‑SMA) connectors are available to maintain a fixed rotational orientation of the fiber, which is useful when coupling into asymmetric optics or systems requiring repeatable alignment.
How do I select the right CuSMA cable (core size and NA) for my laser application?
Selection should be based on (1) Laser power: For higher average powers approaching 400 W, choose larger core sizes (e.g., 600–1000 µm) to reduce power density at the fiber input face; (2) Beam quality and spot size: Smaller cores (100–400 µm) support tighter focus and higher brightness but require better beam quality and alignment; (3) Numerical aperture: The standard NA = 0.22 matches most industrial diode and fiber lasers. If your laser has a smaller divergence or you need improved beam quality, an NA = 0.12 or graded‑index version (available on request) may be advantageous; (4) Cable length and routing: Shorter lengths (2–3 m) minimize optical loss and are suitable for compact systems, while 5 m and longer custom lengths are useful for flexible machine layouts. When in doubt, consult the laser manufacturer’s fiber coupling specifications and match core size, NA, and connector type to their recommended parameters.
