PM Couplers (Polarization Maintaining Couplers)

As the number of channels increases with DWDM, the higher intensity of light in a fiber induces various non-linear effect of light, causing signal distortion in a long span. Fujikura have developed FutureGuide®-LA, which is designed for inhibiting non-linear effect with non-zero dispersion characteristic at 1530-1565nm region and with large effective area, offering for long distance DWDM transmission in C and L bands.

Pump LD wavelength stabilizer is used for external cavity of pump Laser Diode. 980nm and 1420-1490nm wavelength ranges are available.

Fujikura PANDA fibers have a superior optical property in polarization-maintaining because of the symmetrical accuracy in cross section and the uniform constitution of stress applying parts. Based on Fujikura's fiber technology, PANDA fibers have a universal quality with not only low polarization-crosstalk and low attenuation but also the broad suitability for fusion-splice or optical connector.
