* 产品描述

产品描述:

所述OP1021 启动条件分析仪是一种方便和紧凑的台式近场和远场扫描仪的光纤。 结合 Windows 应用程序OPL-LCA ,用户可以扫描并轻松绘制任何兼容光纤的近场和远场模式。除了将近场和远场模式与标准发射模板进行比较之外,还计算了环绕通量并将其与各种 IEC 模板进行了比较。


仪器的光学接口接受所有标准 2.5mm 插芯。可根据要求提供其他连接器尺寸。


OP1021可配有850nm的两个内部LED和1300nm的波长。内部 105/125µm、0.22NA 光纤允许在大多数应用中进行溢出测试。




产品特点:

近场

近场 (NF) 描述了辐射源表面或光纤末端的光功率密度。


该OP1021符合IEC 61280-1-4规范针孔的扫描机制来收集近场分布。  使用显微镜物镜,光纤端面被成像到一个平面上。一个直径为 100µm 的针孔位于该平面上的探测器前面,并在投影图像上进行机械扫描以收集近场分布数据。


该OP1021有3个软件控制定位,允许在移动所有3个空间维度。  一个允许将图像聚焦(z 轴),而两个允许系统扫描投影平面(x,y 轴)以实现居中目的。这款近场扫描仪具有 +/-250µm 的有效扫描范围和 0.1µm 的分辨率,能够分析大多数光纤端面和发射。


远处的荒(田)野

OP1021符合标准在TIA-455-177-B技术1指定用于从远场测量情节数值孔径。OP1021 中的远场扫描是通过沿径向运动将法线旋转到输入光纤端面而形成的半圆弧移动 100μm 芯光纤来执行的。  接收器是一根 100/250µm 光纤,放置在距离输入光纤端面约 5 厘米的位置,并且可以围绕径向中心从 -0.5 弧度旋转到 +0.5 弧度。


远场扫描说明了光纤的远场轮廓。对于多模光纤,如果被测光纤过满,远场扫描将产生数值孔径。


对于单模光纤,模场直径可以从远场剖面测量。  模场直径测量根据TIA/EIA-455-191A和IEC 60793-1-45 进行。所述OP1021使用直接远场方法来获得远场分布,这是模场直径的基准测试方法。  MFD 测量有助于单模光纤的开发和鉴定。

详细信息

Product Description:
The OP1021 start-up condition analyzer is a convenient and compact optical fiber for desktop near-field and far-field scanners. Combined with the Windows application OPL-LCA, users can scan and easily draw any compatible optical fiber near-field and far-field modes. In addition to comparing the near-field and far-field modes with standard emission masks, the surround flux was also calculated and compared with various IEC masks.


The optical interface of the instrument accepts all standard 2.5mm ferrules. Other connector sizes can be provided upon request.


OP1021 can be equipped with two internal LEDs of 850nm and a wavelength of 1300nm. The internal 105/125µm, 0.22NA fiber allows overflow testing in most applications.


Features:

Near field
Near field (NF) describes the optical power density on the surface of the radiation source or at the end of the fiber.


The OP1021 complies with the IEC 61280-1-4 specification pinhole scanning mechanism to collect near-field distribution. Using a microscope objective, the end face of the fiber is imaged onto a flat surface. A pinhole with a diameter of 100 µm is located in front of the detector on this plane and mechanically scans the projection image to collect near-field distribution data.


The OP1021 has 3 software controlled positioning, allowing movement in all 3 spatial dimensions. One allows the image to be focused (z axis), while two allow the system to scan the projection plane (x, y axis) for centering purposes. This near-field scanner has an effective scanning range of +/-250µm and a resolution of 0.1µm, capable of analyzing most fiber end faces and emissions.


The barren (field) fields in the distance

OP1021 conforms to the standard specified in TIA-455-177-B technology 1 for plotting numerical aperture from far-field measurements. The far-field scanning in OP1021 is performed by moving a 100μm core fiber in a semicircular arc formed by rotating the normal to the end face of the input fiber along a radial motion. The receiver is a 100/250µm fiber, placed about 5 cm away from the end face of the input fiber, and can be rotated from -0.5 radians to +0.5 radians around the radial center.


The far-field scan illustrates the far-field profile of the fiber. For multimode fiber, if the fiber under test is too full, the far-field scanning will produce a numerical aperture.


For single-mode fibers, the mode field diameter can be measured from the far field profile. The mode field diameter measurement is carried out according to TIA/EIA-455-191A and IEC 60793-1-45. The OP1021 uses the direct far-field method to obtain the far-field distribution, which is the benchmark test method for the mode field diameter. MFD measurement helps in the development and qualification of single-mode fiber.
