    for Use

The device is designed to solve the problem of optical communication lines compaction at a single wavelength. Principle of operation is based on the non-reciprocal rotation effect of the polarization plane in Faraday rotators. 

This device is implemented on micro-optical, birefringent, magneto-optical elements. The functional unit of the circulator is built on volume optics: YIG, rutile, prisms.

Features:

  • Vibration resistance
  • No fiber welding
