Multi-core Fibers – Buying Guide & Suppliers
Find all you need for professional sourcing of multi-core fibers:
- Technical background information – with RP Photonics quality
- Editable supplier selection criteria – define what you need
- Directory of suppliers – expert-curated, not limited to advertisers
Purchasing high-value photonics products is a substantial responsibility. Using a structured decision-making process and high quality supplier data helps a lot:
- Find all relevant suppliers (not limited to advertisers).
- Our interactive tool conveniently assists you in defining and applying your application-specific requirements.
Note that purchasing decisions based on just a few randomly picked suppliers and without carefully defined specifications are risky; therefore, we strongly recommend using our data and tool. See also:
You may consider using a general-purpose AI tool for supplier search, but you are usually better served here:
- Expert-curated comprehensive and regularly updated supplier lists instead of a quasi-random selection based on unknown, varying and possibly outdated data sources
- Consistent system of product categories and semantic search for finding the right categories
- Technical/scientific background information directly available where you need it
- AI-based assistant for defining your requirements and checking selected suppliers
Basically, human expertise plus tailored AI beats general-purpose AI.

Define Supplier Selection Criteria
It is essential to fully understand and clearly define your requirements before you purchase.
Here, you can define clear requirements according to your specific needs, beginning with some criteria suggested by RP Photonics:
| 1. |
| 2. |
| 3. |
| 4. |
| 5. |
| 6. |
You can later use these requirements for checking the suitability of found product offers of suppliers, for requesting quotations, and for documenting your supplier search.

34, Rue de la Croix de Fer 78100 Saint Germain-en-Laye France See us at Photonics West 2026 in San Francisco, Jan. 20–22 (booth 5039)! | ⚙ hardware  Based on our original telecom experience of making twin core fibers for add/drop multiplexers, Exail (formerly iXblue) in collaboration with Photonics Bretagne is now offering multi-core fibers for shape and temperature/strain sensing. Multi-core fibers can be used in a large variety of sensing application where the need to reduce the global footprint is also required for cables and connectors. Our multi-core fibers have photosensitive cores, allowing Fiber Bragg Grating (FBG) inscription, and can be tailored to match the exact customer specifications. Product-specific web page |
Innovation in every fiber Fibercore LimitedUniversity Parkway Chilworth Science Park Southampton SO16 7QQ United Kingdom See us at Photonics West 2026 in San Francisco, Jan. 20–22 (booth 5223)! | ⚙ hardware  Multi-core fibers provide a platform for the next generation medical shape sensing, data center transmission cables and temperature/strain sensing. They can be used to dramatically reduce the amount of space required for connecting to photonic integrated circuits, and other applications that require precise alignment of several optical cores in a small space. By combining multiple cores for multiple signals into a single multi-core fiber with a 125 micron diameter, designers have a new capability not offered by single fibers. In addition, the fiber has photosensitive cores, allowing fiber Bragg grating (FBG) inscription into each core. Product-specific web page |
Bannhaldenstr. 38 8500 Frauenfeld Switzerland | 💻 software  With the RP Fiber Power software, you can simulate details of multi-core fibers, e.g. the coupling between the different cores. Using a versatile Power Form, you can already cover many simulations out of the box. With a custom script, even very special things can be investigated. |
