Abstract
Methods, systems, apparatus and devices for a variable fiber optic delay line that includes an electro-optic modulator for receiving and modulating an input signal, a switchless discrete long time delay module for injecting a long time delay into the modulated signal to produce a long delayed signal, and a switchless analog variable short delay module injecting a variable short time delay into the long delayed signal for a delayed output signal having a delay approximately equal to the long plus the short time delay. The module may also include non-dispersive single mode fibers for transmission between components and a circulator coupled for routing the input signal to the discrete long time delay module and routing the first delayed output signal to the analog variable short delay module. The VFODL can be used for Radio Frequency, digital electrical signals requiring time delay and amplitude processing or optical signal processing.
