SmartClass OLA-55M(光学电平衰减器)是SmartClass产品系列的最新设计。在该单元中,已向众所周知的SmartClass OLA-55添加了更多功能,该产品是用于系统测试,安装,维护和生产单模光纤的面向未来的仪器。由于最小化差分群延迟(DGD),SmartClass OLA-55M也适用于40 Gbps系统。
自动电平控制器模式
大多数应用需要定义的功率电平,而不是一定的衰减电平。标准衰减器仅允许设置衰减值。与此相对,SmartClass OLA-55M的电平控制器模式允许直接设置精确和定义的光功率电平。它集成了衰减器和功率计的功能,因此避免了使用单独的功率计调节功率水平的额外步骤。在这种模式下,衰减器会自动平衡输入功率电平变化的变化,并提供稳定的输出电平。

The SmartClass OLA-55M (optical level attenuator) is the latest design of the SmartClass product range. In this unit more functions have been added to the well known SmartClass OLA-55, which is a future-proof instrument for system testing, installation, maintenance, and production of singlemode fibers. Due to minimized differential group delay (DGD), the SmartClass OLA-55M is also suitable for 40 Gbps systems.
Automatic level controller mode
Most applications require a defined power level rather than a certain level of attenuation. A standard attenuator only allows the setting of an attenuation value. Against it, the level controller mode of the SmartClass OLA-55M allows direct setting of a precise and defined optical power level. It integrates the function of an attenuator and a power meter and therefore avoids extra steps to adjust the power level with a separate power meter. Being in this mode the attenuator is automatically counterbalancing the changes of varying input power level and provides a stable output level.
