In-line Polarizer在线起偏器:the In-line Polarizer is designed to pass the light with the specified polarization,blocking the others.the function is tranform non-polarized light into linearly polarized light, for the high extincton ratio.It is also used to enhance the extinction ratio of the signals of precision measurement system, fiber sensor, high speed test instrumentations where the high extinction ratio prosper is required.

InGaAs带放大平衡光电探测器

F-tone Networks生产这些平衡光电探测器相当于平衡接收器,通过两个光学输入信号相减消除共模噪声,这样可以从干扰噪声本底中提取时减小光信号路径中的变化。探测器包含两个平衡的光电二极管(PIN)和一个超低噪声、高速跨阻放大器。两个光电二极管相互匹配,具有极佳的共模抑制比(CMRR),从而更好地降低噪声。请参靠下表中各型号指标了解更过信息。所有探测器都都具有3个母头SMA电连接端口,用于减少噪声,除跨阻放大器的RF OUT端口外,Monitor+和Monitor-端口可以单独监控每个光电二极管的响应。

InGaAs雪崩光电探测器

F-tone Networks提供雪崩光电探测器(APD)比带放大光电探测器（PIN）,同样带宽下具有更高的灵敏度和更低的噪声,因此非常适合用于低光功率应用,一般而言,雪崩光电二极管利用内部增益机制提高灵敏度。在二极管上施加高反向偏压产生强电场。当一个入射光子产生一个电子空穴对时,电场使电子加速,导致由碰撞电离产生次级电子。所产生的电子雪崩将产生几百倍的增益,用乘法因子M表示,M因子与反向偏压和温度有关。M因子随温度降低而增大,随温度升高而减小。因此我们所有雪崩光电探测器都提供温度补偿,无需外置温控。目前我们只提供光纤耦合的雪崩光电探测器(APD),这些探测器的集合覆盖从可见到近红外(1100-1700 nm)的感应范围；请参考下表我们每个光电二极管指标,了解每个探测器的确切探测范围。

Integrated Tap Photodiode Isolator

           The Integrated Tap Photodiode Isolator (TPDI) integrates the functionality of a miniature polarization insensitive isolator with a tap photodiode for power monitoring in one package. The product provides a more compact solution in EDFA or other modules where both Isolator and monitoring function are needed.
