Page 6: Intended Use
The ERM200, ERM210, and ERM220 devices are used in photonics re- search and development applications. The ERM200, ERM210, and ERM220 devices are designed for laboratory use only. These devices may not be used or integrated into equipment that is applied in pharmaceutical, medical or military applica- tions. -
Page 7: Introduction
PM fibers or pigtailing of laser diodes with PM fibers. The ERM2xx series models cover different wavelength ranges from 400 nm up to 2500 nm. The ERM200 module is optimized for 600 nm to 1600 nm, the ERM210 module for 400 nm to 700 nm, and the ERM220 module for 1200 nm to 2500 nm. -
Page 8: Getting Started
Fiber Connector Adapters To accommodate for the use of the ERM2xx modules with different PM fiber connectors, Thorlabs of- fers 6 different adapters for the connectors noted in parentheses: ERM2F (Wide-Key FC/PC), ERM2F2 (Narrow-Key FC/PC), ERM2A (Wide-Key FC/APC), ERM2A2 (Narrow-Key FC/APC), ERM2L (LC/PC), and ERM2S (SC/PC). -

2. Connect the ERM2xx module to the power network using the supplied power cord. 3. Identify the fiber adapter for the ERM2xx module which matches the connector on the fiber un- der investigation. The available Thorlabs fiber adapters for the ERM2xx series are listed in the chapter Ordering Codes and Accessories. -
Page 10: Adapter Mounting
SC/PC Mounting steps 1. Push the adapter with the side labeled "Thorlabs" onto the fiber adapter connection port. 2. Screw the locking ring on the adapter to the port to secure the connection. 3. Mount the fiber connector to the adapter on the ERM2xx device. -

Then press RETURN. The minimum ER value measured at that moment is then displayed in the ERmin display. 3. ERmax shows the maximum extinction ratio in dB since the last ERmax-monitor reset was per- formed. It also shows the corresponding misalignment angle in degrees: Rev: 1.0, 24-Jul-2023 © 2023 Thorlabs Page 7... -

Page 18: Operating Principle
40.0 43.0 50.0 If the DOP posts a challenge in a particular PER measurement application, a more complex measure- ment system like Thorlabs' Polarization Measurement System PAX1000 Series is required. PER and PM fibers As long as the linearly-polarized light of a broadband source travels along the slow (or fast) axis the po- larization is maintained and the ERM2xx module will show a high PER. -
Page 19: Light Source Considerations
3. Rotate the PM fiber relative to the laser diode until the displayed ER value is at a peak. To receive more stable readings, increase averaging. Rotate the fiber only slightly relative to the laser diode. 4. To determine and set the ERmin value, change to the ERmin mode. Rev: 1.0, 24-Jul-2023 © 2023 Thorlabs Page 15... -
Page 20: Aligning A Pm Fiber Patch Cable
This section describes how to use the ERM2xx module to align a PM fiber patch cable. For this, Thorlabs recommends using an SLD or ASE as a light source rather than a laser diode. The Extinction Ratio measurement of a PM fiber with an SLD can be done in the following way: 1. -
