High Speed and High Dynamic Range

In Model 1474-A (shown left) an InGaAs PIN photodiode (shown) is followed by a low-noise, linear, high-bandwidth amplifier to provide a 38 GHz bandwidth. In Models 1484-A and 1484-A-50 a larger GaAs photodiode is followed by the same amplifier to provide a 22 GHz bandwidth.

Singlemode or Multimode Fiber

In models with single-mode fiber the optical signal is delivered to the PIN photodiode through a 0.1 m, 9-um core optical fiber, while in the Model 1484-A-50 the signal is delivered through a 50-µm core graded-index multimode fiber of the same length. An internal lens in the 1484-A-50 focuses the light onto the small high-speed PIN photodiode.

Instrument Quality in a Small Package

The small size of the modules allows you to connect them directly to your test instrument or another high-speed component. This eliminates the need to follow the photoreceiver with coaxial cable, which can distort time-domain waveforms and attenuate CW microwave signals.

Low-Noise Amplifier

The amplifier combines moderate gain and low noise to reduce the input-referred noise floor of your system. It also maintains linearity at high output levels, providing a high dynamic range.
