Overview
The TIA-4000 is comprised of a fiber coupled InGaAs APD detector combined with a variable reverse bias voltage network and fast transimpedance amplifier. The output of the unit brought out to a type K female SMA connector. Light falling on the detector generates a positive-going proportional current. This current, multiplied by the transimpedance produces a voltage that is proportional to the light incident on the detector surface.
Normally the unit is used to drive a coaxial cable, this cable should have a 50 ohm characteristic impedance and be terminated with a 50 ohm load at the oscilloscope or other measuring device to be used.
The active area of the TIA-4000 is 30 microns in diameter. It is coupled to a single mode optical fiber. Typical optical return loss is 52 dB and is caused primarily by the FC/APC connector employed. The applied bias voltage controls the gain of the APD. This voltage in turn, is controlled by means of the two push buttons on the top panel. The rightmost button increases the gain and the leftmost button decreases the gain. There are 64 discrete gain settings that are retained in non-volatile memory when the power is turned off.
Thus the gain setting will be retained even though power is disconnected from the unit.
