Project Description

2μm Polarization Maintaining Tap Isolator Hybrid

The 2000nm Polarization Maintaining Tap Isolator combines a tap coupler and polarization maintaining isolator into a single compact package, which splits the light from the input PM fiber into two output PM fibers, and blocks the reflected light from the terminal, with a single compact package and low cost and lower insertion.  It has high extinction ratio, low insertion loss and high isolation. The component is ideal for fiber amplifier and fiber optic system where signal monitoring is required.

If you do not see a standard PM Tap Isolator Hybrid that meets your needs, we welcome the opportunity to review your desired specification and quote a custom PM Tap Isolator Hybrid. Requests for custom fiber pigtails, different wavelengths, tap Ratio and handling power of operation or other specific needs will be readily addressed.

  1. Above specifications are for device without connector.
  2. 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 transmit through the connector less than 2W.
  3. For >10W high power applications, we will use heat sink package, contact DK Photonics for details.

Package Dimension

*Due to ongoing design improvements, the package size is subject to change. Please contact DK Photonics for confirmation.
