1580 New Focus 12-GHz Amplified Photoreceiver

The Newport / New Focus 1580 12-GHz Amplified Photoreceiver's high-speed measurements allow for measurements down to a few microwatts that are made easy. This module converts optical signals to electronic signals, in effect, giving any high-speed / high frequency instrument in your lab an optical input. The small size of the module allows you to connect it directly to your test instrument. This eliminates the need to follow the photoreceiver with coaxial cable, which can seriously distort picosecond pulses and attenuate microwave signals.

The Model 1580 uses a GaAs PIN photodiode designed for high responsivity in the 780-870-nm wavelength range. The internal 62.5-µm multimode fiber which delivers light to the photodiode permits the use of input fibers with cores of 62.5 µm or smaller, including single-mode fibers. The high-speed amplifier which follows the photodiode produces a clean impulse response with minimal ringing, making the Model 1580 ideal for digital communication measurements.

The Model 1580 has a negative conversion gain due to the inverting amplifier used. If you are using an oscilloscope and you want a positive output, use the 'scope's inverting x(-1) function.
