The OPDL product line can provide time delay capabilities for Radio Frequency (RF) input sig-nals with instantaneous bandwidths from DC to over 60 GHz, are packaged in modular en-closures, as well as rack chassis configurations, and can support time delays exceeding 5 ms. The distance the light travels in free space is precisely controlled, either by controlling the separation between the input and output optics, or by. High Performance Fiber Optic Delay Lines Enable Accurate Time delays from picoseconds to 5 milliseconds. The Microwave Photonic Systems Optical / Photonic Delay Line (OPDL) family of products ex-hibits industry leading performance with the smallest volumetric footprints available at eco-nomical. We provide a full range of best-in-class optical and microwave delay solutions, including ultra-fast nanosecond variable delay, motor-driven delay lines, customer-defined fiber coil length selective delay, high-resolution digitally switching delay lines, RF integrated delay systems. We produce. Piezoelectric driven switches are especially designed for high switching speeds in the millisecond range. It provides an expert-curated supplier directory, buyer-focused technical background information, and structured selection criteria to support professional procurement decisions.
