Polarisation Extinction Ratio Meter

The ERM-202 is a dual channel polarisation extinction ratio (PER) meter specifically designed to simultaneously measure the PER and power ratio of a device with two polarisation maintaining (PM) outputs, such as a Y-branch fibre gyro IOC, PM coupler (PMC), or polarisation beam splitter (PBS), as well as evaluate the performance (output DOP) of depolarisers.

Features

• Two measurement channels
• Simultaneous PER & power ratio testing
• >50 dB PER range
• Bright OLED display
• High angular resolution
• Store and recall functions

Applications

• IOC PER & coupling ratio tests
• PMC & PBS PER & coupling ratio tests
