The Polarization Maintaining Isolator &BPF, a two port micro-optic device built with PM panda fiber is a combination of a BPF and an isolator in a compact package. The PM BPF&isolator features low insertion loss, high isolation, high extinction ratio and high reliability and stability. The device guides optical light in one direction and block out unwanted noise signals, eliminates back reflection and back scattering in the reverse direction. The device can be built with bare fiber, or 900um jacket cable. The PM Panda Fiber BPF Isolator is widely used in amplifier systems, fiber optic systems and fiber lasers.

If you do not see a standard BPF&isolator that meet your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed. OPC PHOTONICS can respond to custom requirements with short lead times.

  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 transmits through the connector less than 2W.
  3. For this 1030nm Isolator, Due to high IL, it is recommended to use average power of <100mW. If you need higher handle power, please look for our 1064nm High power isolator.

For this 1064nm Isolator, Due to high IL, it is recommended to use average power of <300mW for single stage and <200mW for dual         stage. If you need higher handle power, please look for our 1064nm High power isolator.

  1. If there is pulse application, please be sure to inform us of pulse energy and peak power.
