1550 nm Motorized Variable Optical Delay Line
Motorized Variable Optical Delay Line provides precision optical path length adjustment of up to 500 ps. Driven by a stepping motor, the MDL has a delay resolution about 10 μm (34 fs). In addition, its advanced motion design guarantees longevity for long-term continuous operation. Low insertion loss and high reliability make this device ideal for integration in optical coherence tomography (OCT) systems, network equipment and test instruments for precision optical path length control or timing alignment.

Motorized Tunable Fiber Delay Line MDL-02-33
Optical Delay Lines
Shconnet
Operating Wavelength Range (Single-Mode Fiber): 1260 ~1650 nm Operating Wavelength Range (Polarization-Maintaining Fiber): 1310±50 or 1550±50 Optical Delay Range: 0~330 ps
The MDL-02 motorized tunable fiber delay line precisely adjusts optical path length over a 560ps delay range. A DC motor and integrated encoder provide drive control, with delay precision better than 0.3μm (1fs) and backlash <8fs. The motor design supports long-term continuous operation. Low insertion loss and reliability suit network and test equipment requiring precise optical-path or signal-timing control, as well as laboratory research. One version has a separate controller and optical-delay module for integration; another is an integrated unit for desktop instruments. Front-panel keys or remote RS232 control operate the device. Single-mode or PM-fiber pigtail inputs/outputs are typical, with free-space versions also available.
