The 1811-FS InGaAs Optical Receiver is a free space, 900 to 1700 nm photoreceiver offering a well-balanced combination of gain, bandwidth, and low noise over the DC to 125 MHz frequency range. Because of it's 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 it's high-level output, reduces the effects of downstream noise sources. For mounting it has a 8-32 mounting thread, and we include an M4 metric adaptor and tool.

1811-FS InGaAs光学接收器是一个自由空间，900到1700 nm的光接收器提供了一个平衡的组合增益，带宽，低噪声在125mhz频率范围。由于它具有较高的跨频增益和较低的噪声等效功率(NEP)，所以它对信号的灵敏度最好，其升降时间短至3纳秒。这种高灵敏度，加上它的高输出，减少了下游噪声源的影响。为了安装它有一个8-32安装线程，我们包括一个M4米制适配器和工具。
