Faraday mirror, 1550nm, rotate the light by 45°, 0.6 dB insertion loss, without a connector.
The Faraday rotator is produced as an important part of the EDFA instrument. It can rotate the light signal by 45° or 90° and it has only one port. The input is the output but the light signal is different.
Features:
Wavelength: 1550nm
Rotation angle: 45°
Insertion loss: ≤0.6dB
Structure: 1x0 port
Applications:
Sensor system
EDFA
Fiber laser
