产品介绍：
Santec OTF-930是一款台式，可选择多种滤波轮廓的可调谐滤波器。OTF-930有多种滤波类型及滤波结构可对应多种光纤光学应用。Santec独有的"Linear Sliding"技术，可实现低 PDL 及 低 PMD。OTF-930带GPIB and RS-232C控制外部接口，可实现远程控制及数据收集。
可编程薄膜诱电性可调谐滤波器：
80nm 调谐范围, 0.01 nm 分辨率
低PDL (< 0.1 dB) & PMD (< 0.1 ps)
峰值搜索功能
特点：
80 nm调谐范围
低插损
低PDL ( < 0.1 dB) & PMD (< 0.1 ps) 整体调谐范围
0.01 nm 分辨率
支持GPIB
应用：
ASE噪抑制
当光信号用EDFAs放大，不需要的放大自发辐射等级(ASE)能降低信噪比。OTF-930有08-S1, 08-S2 或12-S2滤波器，能去除ASE噪，并减少受损。
波长通道选择
03-S2滤波器特别适合从100 GHz grid选择单DWDM波长。其他滤波器可以选择其他ITU grid间隔信号。
非相干光源
当搭配宽带光源用时，OTF-930可以作为一个可调谐光源。虽然输出功率相对低 (- 30 to - 20 dBm)，但是非相干光对于受相干共振影响或者非线性干扰影响的应用，特别有用。

Application:
ASE noise suppression
When optical signals are amplified with EDFAs, unwanted amplified spontaneous emission levels (ASE) can reduce the signal-to-noise ratio. The OTF-930 has 08-S1, 08-S2 or 12-S2 filters to remove ASE noise and reduce damage.
Wavelength channel selection
The 03-S2 filter is ideal for selecting single DWDM wavelengths from the 100 GHz grid. Other filters can select other ITU grid spaced signals.
incoherent light source
When used with a broadband light source, the OTF-930 can be used as a tunable light source. Although the output power is relatively low (- 30 to - 20 dBm), the incoherent light is especially useful for applications affected by coherent resonances or non-linear interference.
