Buying Large-core Fibers
Optical fibers are available with particularly large fiber cores. Some of them also have large mode areas, while others are highly multimode. These fibers are used in applications requiring high power transmission and low nonlinearity.
Making Good Purchase Decisions
As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.
NEW: Structured Decision Process
Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

The large mode area prevents nonlinear effects and material damage. With standard fibers, you trade large mode areas for single-mode operation. With our large mode area fibers, you get single-mode operation in a wide range of wavelengths. Also available in a polarization-maintaining version. Product-specific web page |
