Description

Ascentta, Inc. offers a compact and high-performance three-port fiber optic circulator designed specifically for polarization-maintaining (PM) applications. This optical device efficiently transmits signals from port 1 to port 2 and from port 2 to port 3 simultaneously.

It is ideal for use in optic sensing systems with fiber gratings and other reflective components. Ascentta also provides multiport circulator modules with a maximum of N<=8 ports. 

Ascentta's 405nm PM circulator can be tuned to required wavelength as well. For other wavelength such as 532nm, 650nm, 785nm, or 850nm, please make inquiries.
