We produce a family of ultra-broadband fiber optical isolators operating over a broad wavelength of up to 160nm. These circulators are polarization-independent, having a flat >25dB typical isolation over the ultra-wide wavelength range, as indicated in the graph below. We offer three wavelength bands centered at 1310nm, 1550nm, and 1900nm. This unique performance attribute makes it an ideal choice for broadband light sources and other optical fiber sensing systems. They are available for SM, MM, and PM transmissions. Agiltron has a volume circulator production operation for making custom-designs meeting special applications or cost requirements. The wavelength and range not listed can be specially ordered.
