The 7-bit Solid State Series Fiber Optical Time Delay provides a variable time delay over a long range up to the millisecond.  This is accomplished by selectively routing optical signals through N fiber segments whose lengths increase successively by a power of 2.  Since each switching element allows the signal to either connect or bypass a fiber segment, a delay T may be inserted, which can take any value (in increments of ∆T) up to the maximum value T. This is achieved using a patent-pending non-mechanical 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 device is designed to meet the most demanding switching requirements of ultra-high reliability and fast response time.
