Optical Variable Time-Delay Line Module consists of groups of switches with several fiber segments of different lengths. Delay length is able to be tailored to meet specific requirements with. Optical Zonu offers varying types of fiber optic delay lines. The Switched Delay Line System is a highly configurable 19” rack mount system that supports up to 212 (4096) switched delays (assumes three J-Chassis J-OPS plug-in modules). The system digitally adjusts. 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.
