INSTRUMENTS

Generating programmable time delay from nanoseconds to milliseconds is
important for various applications ranging from wireless communications to
radar, optical communications, and measurement systems. General Photonics’
TimeRITETM programmable optical delay generator is the first such product on the
market. With a total delay range up to 0.25 ms (75 km) and a delay resolution
up to 12 bits, this easy-to-use instrument features low insertion loss (~0.5 dB
per bit), low delay dependent loss (DDL<0.2 dB), low polarization dependent loss,
and fast delay changing speed (<0.5 ms). When operating in manual mode, different delay values can be selected and stepped up
and down with a dialing knob. When in auto mode, the instrument scans through a set of delays with user-defined range, starting and
stopping values, step size, and time interval between delay changes. The instrument also features a double-pass mode to double the
total delay range by passing the light through the optical path twice. A polarization maintaining option is also available for the doublepass input and output ports. By connecting a fiber optic RF or digital transmitter at the input and a fiber optic RF or digital receiver at
the output, programmable delay for RF or digital signals can be readily obtained. At General Photonics, we manage delay to make your
timing right.
