Switchable RF optical fiber delay


delay/P is a switchabe optical RF fiber delay. It is a system that introduces a user configurable time delay in an RF signal. This delay is introduced using a Radio-over-Fiber system that offers much higher performance than acoustic or coaxial delay lines. RoF systems provide constant delay and repeatable phase and group delay in a broad frequency range. Moreover, the use of optical fibers also delivers EMI immunity, high stability against temperature changes and high mechanical flexibility.
delay/p provides 2^N switchable delays (number of bits N) whose values depend on the fiber reels lengths connected to the system (N+1 fiber reels). In addition, these fiber reels are user accessible and fully replaceable for maximum flexibility and reconfigurability.
delay/p is available in OEM version that provides a direct user interface (with no microcontrollers or intermediate communication protocol) based in a DB15 connector that includes monitoring signals, control signals and power supply so easy and flexible integration as subsystem is allowed.
Custom specifications are supplied upon request.
