This 1550±15nm dual-stage polarization-maintaining fiber isolator uses Corning PM1550 polarization-maintaining fiber and is specifically designed for C-band optical systems requiring unidirectional light transmission, reverse light suppression, and stable polarization. The dual-stage optical structure provides isolation of at least 45dB, reducing the impact of reflected light on lasers, amplifiers, and other sensitive optical components.
Q1: What is the main function of a two-stage polarization-maintaining isolator?
A two-stage polarization-maintaining isolator allows optical signals to propagate in a specified direction while suppressing reflected optical signals. It can be used to reduce the impact of reflected light on lasers, optical amplifiers, and other polarization-sensitive devices.
Q2: What are the main optical parameters of this product?
Specifications
| Parameter | Value |
|---|---|
| Operating Wavelength | 1550±15nm |
| Insertion Loss | IL≤0.9dB |
| Isolation | ISO≥45dB |
| Extinction Ratio | ER≥21dB |
| Return Loss | RL≥55dB |
| Maximum Optical Power | 500mW |
Q3: What is slow-axis operation and fast-axis blocking?
This device only allows polarized light aligned with the specified slow axis to pass through; light orthogonal to the fast axis is blocked. During installation, ensure that the input light polarization axis is aligned with the device's slow axis.
Q4: In which direction should the optical signal be connected?
The steel tube surface has arrows indicating the permissible forward light transmission direction. Reverse installation will prevent the device from achieving the specified insertion loss and isolation performance.
Q5: What fiber and connectors does the product use?
The product uses Corning PM1550 polarization-maintaining fiber, equipped with FC/APC fan-port connectors at both ends.
Q6: What are the product length and package dimensions?
Total length including connector: 100±10cm
Steel tube encapsulation size: φ5.5*38mm
Sleeve specification: 0.9mm blue sleeve
Q7: What is the operating temperature range?
The specified operating temperature range for the product is −5°C to 70°C.
Q8: What precautions should be taken when using 500mW optical power?
In actual use, ensure that the input wavelength, polarization axis direction, connector end face cleanliness, and heat dissipation conditions meet the requirements. The maximum optical power is 500mW and should not be exceeded.
Q9: Is a test report provided?
A neutral English test report is provided, which can be used to record insertion loss, isolation, extinction ratio, return loss, and other test items confirmed by both parties.
Q10: How is the product packaged?
The product is packaged in a blister pack with a numbered tube for easy port identification, transportation protection, and batch management.
