Terahertz TIA-525I-ST - InGaAs, DC to 125 MHz O/E Converter with ST Fiber Interface

The TIA-525 optical receiver is a convenient, easy to use O/E converter. It is extremely useful in a variety of laboratory and fi eld service situations where a quick check of the operation of a laser source, optical transmitter, or the output of a fi ber optic communications link is required. The unit conveniently mounts directly on the vertical input BNC connector of your oscilloscope, digitizer, or other readout device.

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 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 confi gurations and exceeds 35 MHz in the highest gain confi guration.

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 unmounted detector is optionally available so that the unit may be used with free space beams. Powered by an internal 9V Lithium battery, or its universal power supply, the TIA-525 is handy to use and store.

The ease of use and convenience 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 and guarantee of satisfaction.
