Electrical and Manual Variable Optical Delay Line

The Variable Optical Delay Line is designed for controlling the optical path delay precisely. These devices are based on based on our unique optical alignment technology. Manual optical delay lines with model number OEVDL-50​, OEVDL-100 and OEVDL-200​ will provide 25 mm, 50 mm and 100 mm air-path variation, corresponding to optical delays of up to 165 ps, 330 ps, and 650 ps respectively. Corresponding electrical version are available with model numbers OEVDL-50E​, OEVDL-100E​ and OEVDL-200E​. This product is an ideal solution for network equipment, test instrument and lab testing applications.
