1030nm/1064nm 1×4, 1x 8 PM Fiber Splitter Modules (1xN)
1064nm Polarization maintaining splitter /coupler modules combine multiple incoming optical fiber inputs into one output, while maintaining the polarization state of the light. It can also be used as a PM splitter.
Our PM coupler modules are assembled using thin-film filter-based 1×2 and 2×2 PM optical fiber couplers, with center wavelengths at 1310nm or 1550nm or 1064nm, and bandwidth of +/-30nm.The Polarization Maintaining Coupler is available in a wide range of coupling ratio. PM couplers are widely used in fiber optic communication systems, Raman Amplifiers and other fiber instrument applications.
DK Photonics offers a large selection of PM Fiber Coupler Module. These devices can handle powers rang from 300mW to 2W or other on request, available in 1xN and 2xN (N<10) types, and have center operating wavelengths ranging from 980 nm to 1650nm.
If you do not see a standard PM Fiber Coupler Module that meets your needs, we welcome the opportunity to review your desired specification and quote a custom PM Fiber Coupler Module. Requests for custom fiber pigtails, differebt, coupling ratio different wavelengths and handling power of operation or other specific needs will be readily addressed.

- above specifications are for device without connector. All parameters are tested at room temperature.
- If tap port coupling ratio is ≤ 5%, ER will be 2dB lower; for ≤1% tap port, ER is out of concern.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
- For >10W high power applications, we will use heat sink package, contact DK Photonics for details.
- If there is pulse application, please be sure to inform us of pulse energy and peak power.
