Delay Line

The YESWEHAVE Variable Optical Delay Line supports continuous, high-precision adjustment of up to 1200 ps (equivalent to 36 cm optical path length), with additional models providing 300 ps - 1200 ps ranges to suit diverse application needs. Delay can be intuitively and reliably controlled via a sliding delay indicator or a motorized system, making it ideal for integration into network equipment, test instruments, and laboratory systems requiring precise optical path length control and timing alignment. Options for single-mode fiber or polarization-maintaining fiber interfaces are available, with wavelength ranges selectable at 1060 nm, 1310 nm, or 1550 nm to match specific system requirements.

Operating Principle

The optical delay line operates based on the principles of refraction and reflection, precisely controlling the propagation time of optical signals by altering the optical path length. Optical signals enter the free-space delay path from the input fiber through a collimating lens, and the delay time is finely adjusted by changing the distance between the input and output ends or by moving a reflective mirror. This design ensures high stability and reliability during operation.

Product Types

Manual Version:
Delay time is adjusted via a manual sliding indicator, providing a simple and stable solution for experimental setups and test platforms requiring flexible control.

Motorized Version:
Driven by a DC servo motor, it supports computer-based remote control and high-repetition-rate scanning, enabling automated testing and long-term stable operation.

The YESWEHAVE Variable Optical Delay Line is an ideal solution for controlling the timing and optical path length of optical signals in high-speed communications, precision measurements, and optical research, providing a stable, flexible, and easily integrated platform for delay adjustment.
