Newport125 MHz Fiber-Optic Receivers
These 125 MHz fiber-optic receivers offer a well-balanced combination of gain, bandwidth, and low noise over the DC–125-MHz frequency range. 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. They have been engineered to eliminate most common sources of noise and drift, and have enough gain to pick up even very weak signals making them ideal optical front ends for systems requiring a low-noise input.

高跨阻增益和低噪聲
具備高跨阻抗增益和低噪聲等效功率 (NEP) 的特點,可提供佳信號靈敏度,上升沿和下降沿時間短 3 ns。這種高靈敏度,結合其高階輸出,可減少下游噪聲源的影響。
直流耦合版本
利用的直流耦合,這些光接收器對瞬態信號給出線性響應,而沒有人工振蕩、尾部或其它異常。
交流耦合版本
具有 25 kHz 低頻衰減的交流耦合版本。這些光接收器可用于測量大型 cw 組件上的小交流信號。為了使對準更容易,交流耦合版本配備了直流光電流監測器輸出。監視器輸出具有 50 kHz 帶寬和 1 V/mA 的增益。
射頻屏蔽
即使在使用調 Q 激光器和其它噪聲設備的實驗室中,縝密的射頻屏蔽和電源輸入濾波也能消除電磁干擾。
