Fiber-Optic Receiver, 900-1700 nm InGaAs, 30 kHz to 850 MHz, FC/PC, AC-Coupled

The Silicon model (1601) provides wavelength coverage from 320-1000 nm, and the InGaAs model (1611) provides coverage from 900-1700 nm. This enables wide bandwidth, low-noise detection of signals distributed over fiber-optic cables or found in high resolution spectroscopy, fiber-optic sensors, optical metrology, and many other applications.

Because of their high transimpedance gain and low noise-equivalent power (NEP), they offer the best in sensitivity for signals with rise and fall times as short as 0.5 ns. This high sensitivity, combined with their high-level output, reduces the effects of downstream noise sources.

These photoreceivers are AC-coupled with a low-frequency roll-off at 30 kHz. A convenient DC-photocurrent monitor output makes alignment easy. The monitor output has a 20-kHz bandwidth and a transimpedance gain of 10 V/mA.

Careful RF shielding and filtering of power-supply inputs eliminate electromagnetic interference, even in laboratories with Q-switched lasers and other noisy equipment.
