Lightel Provides Faraday Rotator Mirror with Integral Time Delay



RENTON, Wash., June 17, 2019 — Lightel Provides Faraday Rotator Mirror with Integral Time Delay

Faraday Rotator Mirrors (FRMs) are used in a number of applications including fiber optic interferometric sensor systems. In order to provide optimum performance, it is desirable to match the optical length between the sensing and reference arms to eliminate the phase difference between the two arms.

Lightel now offers a FRM with a built-in adjustable time delay. The device allows the technician to adjust the optical path length of one of the arms of the interferometer (up to 16mm) to effectively provide zero phase delay. The component is available at 1310nm or 1550nm wavelengths with 250 micron bare fiber or 900 micron loose tube and FC, SC, or LC ultra and angle polished connectors.
