The High-power Isolator &BPF is a combination of a BPF and a TGG based isolator in a single package. The BPF & isolator features low insertion loss, high isolation, high extinction ratio (PM) 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 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. DK Photonics can respond to custom requirements with short lead times.

Performance Specifications

1. Above specification are for device without connector, and may change without notice. Other center wavelengths and bandwidths can also be customized, but MOQ is required, please contact us.
2. IL is 0.3 dB higher and RL is 5 dB lower, ER is 2dB lower (PM type) for each connector added.
3. The pass optical power is 2 W only for connector added, the connector is only used for performance testing at low power, higher power requires splicing fibers.
4. Type B: Both axis working, Type F: Fast axis blocked, the default is Type B if without request (Only for PM type).
5. If there is pulse application, please be sure to inform us of pulse energy and peak power.
6. For high continuous power, we will add a port to export the blocked forward signal light to reduce the heat dissipation of the device. The user only needs to export it to the heat dissipation shell when using it.
