Battery Operation (not included)
The TIA-950 is comprised of a fiber coupled detector and two amplifier stages. The first amplifier is a transimpedance
stage which converts the detector output current to a voltage by passing it through a resistor of 1 200 . Additional amplification
is optionally provided by the second stage which also serves to provide 50 ohm drive capability.
Either AC or DC coupling between the stages may be selected. The overall bandwidth of the unit is determined by the first stage
transimpedance. It is in excess of 750 MHz when the Gain switch is in the 1200 position and is 250 MHz in the 12000 position.
The overall responsivity of the unit in terms of Volts/Watt is the current responsivity of the detector multiplied by the transimpedance
and further multiplied by the second stage gain.
For example, the sensitivity of the unit at a wavelength of 1300 nm would be 0.8A/W x 1200 V/A x 10 = 10 000V/W.
The selection of AC interstage coupling is useful when the user needs to examine a small signal in the presence of a large DC
optical component, (e.g. baseband fiber optic video). This will preclude the last stage from saturating on the DC component.
Otherwise, DC coupling should be employed.
When using the TIA-950 mounted on an oscilloscope, the scope should have its input set to either 50 ohm 1 Meg ohm input
impedance(bandwidth will be maximum when using 50 ohms). If driving a coaxial cable, the cable should have a 50 ohm characteristic
impedance and be terminated with a 50 ohm load.
Note that the signal amplitude will be reduced by a factor of two whenever the load is 50 ohms..
