Variable RF/Microwave Delay Line Module

Turn-Key solution for all applications

The VODM Series Optical Delay Module selectively routes an input 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 and resolution defined by customer. We offer several switching choices of non-mechanical high reliability switching; ultra-fast nano-second switching; and low loss MEMS switching. PM fiber and integrated optical amplification versions are also available. The module utilizes our unique low loss fiber coil winding technology. The module front has an input fiber and an output fiber and LEDs indicating the chosen fiber loops in each operation state. The driving electronic is packaged inside and interfaces with a GUI computer through RS232, RS485, USB, or RJ45.
