Non-Mechnical Variable Photonic Time Delay Module

The SSTD Series Photonic Time Delay Module selectively routes optical signals through N fiber segments whose lengths increase successively by a power of 2. The module therefore provides N bit resolution of digitally variable time delay with a maximum delay time defined by customer. This is achieved using a patented non-mechanical optical switching configuration and activated via an electrical control signal. Latching operation preserves the selected optical path after the drive signal has been removed. The solid-state configuration eliminates the need for mechanical movement and organic materials. The module has an input fiber and an out fiber.  Front panel LEDs indicates the chosen fiber loops in each operation state. PM and high power versions are also available.
