1310/1550nm Free Space Dual Stage Isolator

The fiber isolator made by Faraday rotation effect is composed of isolator core, branch fiber collimator and sleeve. External magnet tube and other components. Rotating magnetic cores with different working wavelengths can be designed according to needs. If the isolation of single-stage iron core is not enough, double-stage isolator core can also be made. Idealphotonics can provide 1310nm/1550nm free space single/double-stage isolators.

Product features：Wavelength optional 1310/1550nm、 Low insertion loss、 High isolation and high stability

Application area：Doppler laser radar、 Fiber application system、 Laboratory research、 R-OTDR fiber, OFDR fiber
