The 1550nm SM Isolator & Band Pass Filter Hybrid Combination is a combination of a BPF and a low power isolator in a single compact package. All input and output fibers are polarization independent. It guides optical light in one direction and block out unwanted noise signals, eliminates back reflection and back scattering in the reverse direction. This product offers integrated solution to fiber laser and fiber amplifier application by combining more functions into a very compact package.

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.
