1811-FC-AC Fiber-Optic Receiver

The 1811-FC-AC InGaAs Fiber-Optic Receiver is a FC connectorized, 900 to 1700 nm photoreceiver offering a well-balanced combination of gain, bandwidth, and low noise over the 25 kHz to 125 MHz frequency range. Because of its high transimpedance gain and low noise-equivalent power (NEP), it offers the best in sensitivity for signals with rise and fall times as short as 3 ns. This high sensitivity, combined with its high-level output, reduces the effects of downstream noise sources. For mounting there is an 8-32 thread, and we include an M4 thread adapter and tool.

An external ±15 VDC power supply, which must be purchased separately, is required. Power supply cables 0923 and 0924 are included with each detector.

High Transimpedance Gain and Low Noise

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 3 ns. This high sensitivity, combined with their high-level output, reduces the effects of downstream noise sources.

RF Shielding

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