The Optiva OTS-ODLS, 18 GHz Internal Fiber Delay Line System is designed for use with Optiva OTS-2 18 GHz transmitter, receiver, optical switches, and EDFA’s. The optical switches allow for up to four separate delays to be used with a maximum delay time of 40 μs. The system delivers unmatched performance for radar testing, signal processing, phased array antennas and phase noise testing with greater flexibility than traditional coax or waveguide solutions.
EMCORE’s fiber optic delay lines provide bandwidth that is essentially independent of fiber length, losses or delays, and triple transit signals that are immeasurable. In addition to enhanced electrical performance, the delay lines provide several mechanical advantages. EMCORE’s technology takes advantage of the rigid yet flexible properties of fiber optic cable to provide repeatable enhanced phase and group delay characteristics. The Optiva OTS-ODLS provides convenient RF input/outputs to connect to the OTS-2 RF transmitter and receiver. Internally, the RF signal is converted to an optical signal and transmitted over a fiber optic link to the receiver and provides the required signal delay time. Delay length and link performance requirements can be tailored over a range of performance levels to meet specific requirements. The Optiva OTS-ODLS system allows for a long delay in a relatively compact package with the superior temperature stability of fiber.
EMCORE’s Optiva OTS-ODLS 18 GHz internal fiber delay line system can be supplied as a complete solution with all modules mounted in a 19” Optiva rackmount enclosure utilizing standard AC power. The Optiva OTS-ODLS family of internal fiber delay lines also includes 22 GHz and 40 GHz frequency options and external Optiva fiber delay line systems for greater delay lengths are available.
