Description

Custom multimode fiber cables and assemblies based on Optran® optical fibers are designed for integration into demanding optical systems.

Fiber cables and bundles can be configured according to application-specific requirements, covering a wide range of wavelengths from UV to NIR depending on the selected fiber type. Assemblies can be manufactured using all Optran® fiber types, including UV, VIS-NIR, broadband and high numerical aperture fibers. Detailed specifications of the individual fiber types, including spectral performance and material properties, are available in the corresponding Optran® fiber listings.

Design parameters such as core diameter, numerical aperture and fiber composition are selected based on the optical requirements of the application. This allows assemblies to be tailored to specific wavelength ranges, transmission characteristics and coupling conditions.

A wide range of customization options is available, including cable length, connector types, protective tubing and multi-fiber configurations. Bundles can be configured for light distribution into multiple individual fibers or structured multi-leg assemblies.

Additional customization options include selection of protective tubing and jacketing materials such as stainless steel, PTFE or polymer coatings, depending on environmental and mechanical requirements. Fiber end preparation can be adapted to the application, including polishing and customized end-face geometries for optimized coupling and system integration.

Assemblies can also be designed for applications involving high optical intensities. Configuration parameters such as core size, fiber type and connector interface are adapted to the specific requirements of laser delivery and high-power optical systems.

Optran® fiber assemblies are used in spectroscopy, laser systems, analytical instrumentation and industrial sensing applications where reliable and application-specific optical performance is required.

Frequently Asked Questions

What types of industrial optical fibers does CeramOptec offer?
CeramOptec offers a broad portfolio of more than 500 silica-based fibers and assemblies for industrial, medical, and research applications. Main product families include: Optran WF and Optran WFNS (all-silica, low OH), Optran UV and Optran UVNS (all-silica, high OH for UV), Optran UVNSS (stabilized high-OH UV fibers), Optran UVWFS (broadband all-silica with low OH and no Cl₂), Optran HUV and HWF (silica core with fluoroacrylate cladding), Optran PUV and PWF (silica core with silicone cladding), Optran WFGE (GeO₂-doped silica), fiber tapers, multi‑core fibers, non‑circular core fibers (UVNCC, WFNCC), safety fibers, metal‑coated fibers, single‑fiber cables, fiber bundles (including fused-end bundles), and custom medical fiber probes.
What is the difference between low OH and high OH all‑silica fibers like Optran WF and Optran UV?
Low OH (low hydroxyl content) fibers such as Optran WF and WFNS are optimized for transmission in the visible and near‑infrared range, with reduced OH absorption bands and low attenuation from about 400 nm up to the IR. High OH fibers such as Optran UV and UVNS intentionally contain more hydroxyl groups, which improves transmission and radiation resistance in the deep UV and UV‑visible range but limits performance further into the infrared. In practice, choose low OH fibers for broadband VIS‑NIR power delivery and sensing, and high OH fibers for UV curing, spectroscopy, fluorescence excitation, and other UV‑intensive applications.
What are the advantages of Optran UVNSS and UVWFS broadband fibers for UV applications?
Optran UVNSS fibers are all‑silica, high‑OH fibers that are additionally stabilized to enhance UV durability and reduce solarization (permanent transmission loss caused by UV exposure). They are suited for long‑term UV power delivery and repetitive pulsed UV laser applications. Optran UVWFS broadband fibers are all‑silica with low OH and manufactured without chlorine (Cl₂‑free), which yields broad spectral coverage from UV through visible to near‑IR with minimized absorption peaks. This combination makes them attractive for broadband spectroscopy, metrology, and multi‑wavelength laser delivery where both UV and VIS‑NIR performance are important.
What are CeramOptec multi‑core and non‑circular core optical fibers used for?
Multi‑core optical fibers from CeramOptec can be made with concentric or individually arranged cores in a common cladding, enabling applications such as multi‑channel sensing, imaging, beam combining/splitting, and structured light delivery. Non‑circular core fibers (Optran UVNCC, WFNCC) feature shapes such as square, rectangular, or polygonal cores. These fibers are commonly used to homogenize beam profiles, improve coupling into rectangular or slit‑shaped apertures, enhance mixing in spectroscopic systems, and optimize power delivery in materials processing where a top‑hat or line‑shaped beam is desired.
What jacket and coating options are available for CeramOptec silica fibers?
CeramOptec offers a wide range of fiber jackets to match mechanical, chemical, and thermal requirements. Options include standard polymer jackets, high‑temperature and abrasion‑resistant jackets, colored jackets for channel identification, and specialty jackets for harsh industrial environments. The company also supplies metal‑coated silica fibers, where the all‑silica fiber is coated with metals such as aluminum, copper, or gold for improved heat dissipation, vacuum compatibility, and robustness in extreme environments. Additionally, anti‑reflection (AR) coatings can be applied to fiber endfaces, and medical fibers and probes can be sterilized and jacketed according to medical device standards (ISO 13485).
Does CeramOptec provide custom fiber geometries, assemblies, and medical probes?
Yes. Beyond standard stock fibers, CeramOptec specializes in customized solutions across the entire value chain—from preform design (via POVD and PCVD methods) to drawn fibers and final assemblies. Customization options include non‑standard core sizes, numerical apertures, non‑circular core geometries (square, rectangular, polygonal), specific jackets and markings, fiber tapers, multi‑core designs, and complex fiber bundles (including fused‑end bundles). For medical and life‑science applications, CeramOptec develops custom fiber probes, instrument interfaces, and sterilizable cable assemblies under ISO 13485, including integration of AR‑coated endfaces and specific connector systems.
How does CeramOptec ensure quality and reliability of its industrial fiber optics?
CeramOptec controls the full manufacturing chain from all‑silica preforms (produced by POVD and PCVD plasma processes) through fiber drawing and final assemblies. This allows tight control over core/cladding geometry, numerical aperture, and material purity, which directly affects attenuation and long‑term stability. Manufacturing is certified to ISO 9001 and ISO 14001 for quality and environmental management, and ISO 13485 for medical devices. Fibers are characterized for attenuation (with comparison charts across product families), and assemblies can be supplied with test data on transmission, NA, and endface quality. This integrated approach is designed to provide repeatable, high‑reliability performance in demanding industrial, medical, and research environments.
