Optiva OTS-ODLS 22 GHz, 40 µs max Internal Fiber Delay Line System DATASHEET | APRIL 2014 MICROWAVE The Optiva OTS-ODLS, 22 GHz Internal Fiber Delay Line System is designed for use with Optiva OTS-2 22 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. Applications Radar System Testing Phase Array Antennas Signal Processing Electronic Warfare (EW) Systems Features 40 µsec Delays Max Switching Option Available Smaller Size and Less Weight - Conserve Rack Space 0.05 - 22 GHz Bandwidth Flat Phase Response Minimal Triple-Transit Echoes Low Link Loss Options Low Temperature Sensitivity Manually and/or Computer Controlled 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 22 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 18 GHz and 40 GHz frequency options and external Optiva fiber delay line systems for greater delay lengths are available. System Design The Optiva platform includes a wide range fiber optic transport solutions for satellite and microwave communications applications including transparent inter- and intra-facility links, video transport, antenna remoting, radar system testing, phased array antennas, signal processing, electronic warfare systems and other high-dynamic-range applications. Optiva is a completely modular, hot-swappable platform with a variety of rackmount or compact tabletop, or wall-mountable enclosures are available. The 3 RU 19” rack-mount, fan-cooled enclosure (Model OT-CC-16F) for the OTS-ODLS internal fiber delay line system can support up to 16 insert cards and utilizes two dual-redundant, hot-swappable, 200 watt power supplies. © 2014 EMCORE Corporation | REV 2014.04 +1 626-293-3400 [email protected] www.emcore.com Information contained herein is deemed to be reliable and accurate as of the issue date.
