偏振消光比测试 (CUBE-ER100) 

CUBE-ER100是一种基于旋转偏振片的偏振消光比测试仪，可用于光纤产品和自由空间光检测。CUBE-ER100的消光比测量动态范围高达52dB, 角度分辨率为0.03°, 工作波长为600nm~1600nm。由于其紧凑的外形尺寸和高达每秒50次的快速测量速度，易于集成到保偏光纤自动对准系统中 。

CUBE-ER100装备有一个用于远程控制的全速USB 2.0端口，一个用于不同CUBE系列模块间互联的UART端口，两个用于保偏光纤自动对准系统闭环控制的模拟输出，以及两个用于测量和控制信号同步的通用TTL输入/输出。CUBE-ER100可以作为主单元来控制偏振优化仪（CUBE-PM100），以便在不连接在线偏振器和保偏连接器的情况下，对保偏光纤环圈和组件进行快速、准确的消光比和角度测量。

CUBE-ER100模块的默认输入为FC适配器，同时有多种输入匹配器供选择， 用来测量SC  或LC 连接器、保偏准直器、光纤阵列、PIC芯片、自由空间平行光束和自由空间点光源。多个CUBE-ER100模块可以组合在一起测量多端口器件， 如保偏耦合器、保偏隔离器、铌酸锂调制器等。

        工作波长可覆盖600~1600nm（波长范围广，可以实现目前市场上630nm、850nm、1064nm、1310/1550nm四台消光比测试仪功能）

The CUBE-ER100 is a rotating polarizer-based polarization extinction ratio (PER) meter for fiber and free-space optical applications. This PER meter has a 52dB PER dynamic range, 0.03 angular resolution, and wide operating wavelength range from 600nm to 1600nm. Because of its compact size and fast measurement speed up to 50 points per second, it can easily be integrated into PM fiber auto-alignment systems. It has one full-speed USB 2.0 port for remote control, one UART port for interconnection between different CUBEs, two analog outputs for the closed-loop control of PM fiber auto-alignment system, and two general-purpose TTL input/output for measurement and control synchronization. CUBE-ER100 can work with polarization maximizer cube CUBEPM100 to perform fast and accurate PER and angle measurements of PM fiber spools, coils, and components without splicing the inline polarizer and PM connectors. CUBE-ER100 module has an FC adapter as the default input; other input accessories are available for SC and LC connectors, PM collimators, fiber arrays, PIC chips, free-space parallel beam, and free-space point sources. CUBEER100 modules can also be stacked to simultaneously measure multiple outputs of PM coupler, PM splitter, Lithium Niobate IOCs, etc.
