JDS
Uniphase偏振相关损耗的万用表都是最快和最准确的可用光万用表。他们测量偏振相关损耗（PDL）单模光纤组件可以使用内部或外部源激光。万用表测量设备的损失为四独立输入偏振态测试下。利用缪勒矩阵计算了PDL全偏振态的平均损失，在IEC国际标准化（613）00-3-12。
万用表容易和迅速改变测量PDL和插入损耗（IL）来测量回波损耗（RL）或权力。测量和显示同时在不到两秒钟的PDL和IL。万用表有一个复杂的光学设计，弥补了在内部参考探测器的光功率的变化。设计保证精确的损耗测量无论在漂移的源动力或输入光耦合效率通过偏振态控制器。综合客运专线标准源检定流量计的标定是特别方便。可以选择一个外部的可调谐激光或双固定的激光源，用于各种波长测量。万用表对PDL敏感元件是理想的，如隔离器，dwdms，光纤布拉格光栅（FBG），光学环行器，开关，衰减器，耦合器，和其他设备的测试精度高和最佳的生产速度是至关重要的。

The JDS Uniphase Polarization Dependent Loss Multimeters are the fastest
and most urate optical multimeters available. They measure polarisation
dependent loss (PDL) of single-mode fibreoptic components using either an
internal laser or an external source. The multimeters measure the loss of a
device under test for four independent input polarisation states. The PDL and
the average loss over all polarisation states are calculated using the Mueller
matrix, internationally standardized under IEC (613)00-3-12.
The multimeters easily and rapidly change from measuring PDL and insertion
loss (IL) to measuring return loss (RL) or power. The PDL and IL are measured
and displayed simultaneously in less than two seconds.The multimeters have a
sophisticated optical design that compensates for changes in optical power at
the internal reference detector. The design ensures urate loss measurements
regardless of drift in the source power or the coupling efficiency of the input
light through the polarisation state controller. The integrated PDL standard
source is particularly convenient for verifying the meter's calibration. An
external tunable laser or two fixed laser sources can be selected for various
wavelength measurements. The multimeters are ideal for PDL-sensitive components,
such as isolators, DWDMs, fibre Bragg gratings (FBGs), optical circulators,
switches, attenuators, couplers, and other devices for which high test uracy and
optimum production speed are crucial.
