Applications

Singlemode Filter WDM (980/1064)

       The Filter Wavelength Division Multiplexer is based on environmentally stable thin-film filter technology. The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality FT coating. These components have been extensively used in EDFAs, Raman amplifiers, WDM networks and fiber optical instruments.

Si带放大平衡光电探测器

高速光电探测器采用可靠高速电路设计,并应用高灵敏度光电二极管和一个超低噪声的互阻放大器,可以有效地减小电信号噪声和畸变。本系列探测器提供多种转换增益可选,满足客户的不同需求。各种不同增益的高速放大光电探测器配有一个SMA-K监测端口,监测互阻放大器上OUTPUT端电信号响应。该类探测器主要用于光谱检测、气体检测、模拟光信号接收、脉冲光探测和光纤传感测量等领域。

Si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(400-1100 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。
