Fiber Optic Delay Line

We introduce a new product made by OptiXs – a Fiber Optic Delay Line. This device is designed to allow a precise variation of the optical path length which is widely used in many application areas such as interferometry, signal processing, telecommunications, etc.

Depending on the selected type, our delay line offers an optical delay range of 330 ps or 660 ps with an unprecedented resolution of < 0.33 fs across the whole range.  You can choose between operating wavelengths of 1550 nm and 2000 nm. In either case a polarization-maintaining (PM) fibers with FC/APC connectors placed on the front face of the case are used. Single mode (SM) fibers are also available.

The delay line comes with a high-resolution stepper motor and a controller which enables a computer based remote operation of the device. For basic use we include an intuitive customized web interface, while ethernet and USB connections provide options for more advanced communication and automatization. Available as a standalone unit or as modular inserts for a standard 19” rack system. This together with state-of-the-art optical performance makes our delay line ideal for advanced applications in coherent beam combining, optical coherence tomography (OCT), or time division multiplexing (TDM).
