Primanex Faraday rotating mirror uses experienced magneto-optical technology. This component verifies has low insertion loss and the degumivity in the environment, making it an ideal indicator in the fiber optic sensing system, the measurement system.

The electrically adjustable attenuator is based on the Faraday rotation effect, by using all solid-state magneto-optical technology, no mechanical moving parts, having ultra-fast response speed (up to 0.3ms), and more reliable performance, longer service life.

The single-mode fiber coupler is made by using the drawing technology. It can be used in Multi - terminal power distribution. It has the advantages of small volume, high stability, low additional loss and low polarization-related loss. It is widely used in optical fiber communication system, CATV systems, fiber-optic LAN and other fields.

The polarization maintaining fiber coupler is fabricated by a special polarization-maintaining fiber, which can divide the polarized light into two beams of the same polarization state as the input light. The product has passed the GR-1209-CORE and GR-1221-CORE reliability tests and various environmental tests, and product performance is very good, stable and reliable, having been in a number of national key projects in bulk applications.
