EMCORE has announced the introduction of the Optiva OTS-ODLS 18, 22 and 40 GHz Internal Fiber Delay Line Systems for delay times up to 40 microseconds.

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. They are ideal for applications such as radar system testing, phased array antenna systems, signal processing, and electronic warfare systems. EMCORE's fiber delay line technology takes advantage of the rigid yet flexible properties of fiber optic cable to provide repeatable enhanced phase and group delay characteristics.

EMCORE's Optiva OTS-ODLS series are the first fiber delay lines designed for the modular Optiva RF and Microwave Fiber Optic Transport System. They provide convenient RF inputs and outputs to connect to an Optiva 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 has a long track record of supplying the highest quality fiber delay lines in a variety of ruggedized form-factors for radar system testing, phase array antennas and electronic warfare systems," said Frank Weiss, EMCORE's Vice President of Advanced Systems. "We are very excited to bring this technology to the Optiva platform where it can be supplied as a complete solution with all modules mounted in a 19" rack-mount Optiva enclosure utilizing standard AC power," added Weiss.

The Optiva OTS-ODLS family of internal fiber delay lines includes 18 GHz, 22 GHz and 40 GHz optimized frequency options, and external Optiva fiber delay line systems for even greater delay lengths will be available soon.
