T he TIA-525 optical receiver is a convenient, easy to
use optical to electrical converter.
It is extremely useful in a variety
of laboratory and field service
situations where a quick check of
the operation of a laser source,
optical transmitter, or the output
of a fiber optic communications
link is required.
The use of surface-mount
construction techniques permits
the unit to be mounted directly on
the vertical input BNC connector
of your oscilloscope or digitizer.
Simply energize the battery powered unit and the optical signal
presented to the fiber input port
is faithfully reproduced on the oscilloscope screen.
Both Silicon and Indium-

Gallium-Arsenide detectors are
available to cover respectively the
400 to 1000 nm or the 900 to 1700
nm spectral regions.
Gains are switch selectable
and provide peak responsivity values of approximately 1000 to
100,000 volts per watt.
AC coupling between stages
may be introduced in order to examine weak high frequency optical signals in the presence of a
strong DC optical component.
The TIA-525 electrical bandwidth exceeds 125 MHz in the low
and medium gain configurations
and exceeds 35 MHz in the highest gain configuration.
The unit’s output stage is fully
capable of driving a 50 ohm coaxial cable terminated in its characteristic impedance.

Fiber connector options include
either ST or FC receptacles. An
unconnectorized detector is available as an additional option so
that the unit may be used with free
space beams.
Powered by an internal,
readily available, 9V Lithium battery, or its universal power supply, the TIA-525 is handy to use
and store. Its low noise performance results from the use of a
shielded case plus its inherent isolation from power lines and ground
loops.
The ease of use and
convienience of this instrument
are matched only by the high performance-to-price ratio that is
typical of products from Terahertz
Technologies. It is also backed by
our standard two year warranty.
