Single Clad Fibers

Germanium-doped single-clad fiber spool

Single clad fibers

The SC-250/14-PM-Ge is a truly single-mode, all-solid-core step-index single-clad fiber.

Based on a unique refractive index control, the 14 μm polarization-maintaining core delivers diffraction-limited output in a single mode. The mode quality is stable over time and independent of coiling.

The fiber offers mode-matching with our DC-135/14-PM-Yb fiber and is spliceable to commercially available pump/signal
combiners.

The Single-Mode Advantage

All our fibers are single-mode, leading to several advantages compared to standard multimode LMA fibers:

  • Better output stability
  • Excellent beam quality
  • No need for tight coiling
  • No coiling-induced mode area compression

If you want more details about how to handle optical fibers: Strip, cleave, and couple them, we have some application notes for you.

Optical fibers require proper handling to ensure a long lifetime and prevent fiber breaking. Read this guideline to learn how to handle optical fiber to keep both the fiber and the operator safe.

Read this application note if you want to learn how to handle our optical fibers, e.g., including how to strip the protective coating, how to cleave the fibers, and how to couple light to and from the fibers.
