Product Description

Precise control of delay time via adjustment of optical transmission distance
Low insertion loss, multi-position delay, picosecond-level resolution
Single-mode fiber, FC/APCconnector

Manual Optical Delay Lines (ODL) consist of input and output fiber collimators along with a motion mechanism, designed to project light into free space and then collect it back into the fiber. By altering the propagation distance of light through the motion mechanism, the optical path delay time can be controlled. The distance between the input and output optical ports (single-pass) or by reflecting light from a movable mirror (double-pass) can precisely adjust the distance light travels in free space. LBTEK's adjustable optical delay lines feature low insertion loss, multi-position delay, and picosecond-level time resolution. They are suitable for applications such as PMD compensation in high-speed communication networks, interferometric sensors, coherent telecommunications, spectrum analyzers, and OCT systems.

Fiber core9 μm

Fiber ModeSingle-mode

Connector TypeFC/APC

Manual Adjustable Optical Delay Line, Single-Pass

Operating Wavelength: 1550 nm
Manually Adjustable Delay Range: 100 mm
Low Insertion Loss, High Return Loss

The LBTEK Manual Adjustable Optical Delay Line (Single Pass) is a device that precisely controls the delay time by altering the length of the delay path between the input and output optical ports. It uses air as the optical transmission delay medium, and the delay distance between the input and output optical ports is manually adjusted via a motion mechanism (i.e., a lead screw guide rail). The device features input and output ports each equipped with a 1 m single-mode fiber pigtail and FC/APC connectors. The manual adjustment range of the lead screw guide rail is 100 mm.

Manual Adjustable Optical Delay Line, Double-Pass

Operating Wavelength: 1550 nm
Manually Adjustable Delay Range: 50 mm
Low Insertion Loss, High Return Loss

The LBTEK manual adjustable optical delay line (double-pass) is a device that precisely controls the delay time by altering the length of the delay path of the movable mirror. It uses air as the optical transmission delay medium, and the delay displacement of the movable mirror is manually adjusted via a motion mechanism (i.e., a lead screw guide rail). The device features input and output ports each equipped with a 1 m single-mode fiber pigtail and FC/APC connectors. The manual adjustment range of the lead screw guide rail is 25 mm, providing a delay range of 50 mm.
