Request InfoOZ Optics LimitedOz Optics Ltd.'s variable fiber optic delay lines can create delays of up to 0.3 ns with 30-fs resolution. By adjusting the distance between the fiber optic collimator and the focuser, which are mounted on a movable translation stage, users can control the delay time within the device. The delay lines are hand-adjustable with either lead screws or micrometers; motorized versions using either servo- or stepper motors also are available. Insertion loss is 1.5 dB over the travel range, and available wavelengths range from 400 to 1625 nm.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 Issue800G and 0dBm 400G TransceiversThe 800G ZR+ and 0dBm 400G ZR+ from Lumentum are compact transceivers that enable IP over DWDM by directly plugging into switches and routers.
