Features

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.

EMCORE’s fiber optic delay lines provide bandwidth that is essentially indepen-

dent of fiber length, losses or delays, and triple transit signals that are immea-

surable. 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 opti-

cal 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 sup-

plied as a complete solution with all modules mounted in a 19” Optiva rack-

mount 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 rack-

mount 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.
