Single
Mode

Single mode 5µm core fiber

Low fiber loss from 400 nm to 1700 nm
Single-mode at all wavelengths
Radiation hard pure silica fiber
Wavelength independent MFD

This single-mode photonic crystal fiber is optimized to exhibit
low loss across the widest possible wavelength region from 400
nm to above 1700 nm while keeping an almost constant mode
field diameter.
The fiber is endlessly single-mode with no higher order mode
cut-off and delivers excellent mode quality at all wavelengths.
The fiber has a standard 125 µm outer diameter and is compatible with all common fiber tools.

Applications

-

Single-mode high power delivery
Mode filtering
Single-mode pigtailing
Short pulse delivery

Typical spectral attenuation and dispersion

This product is also available in a polarization-maintaining version
as the LMA-PM-5.
