1550nm Polarization Maintaining In-Line Polarizer
1550nm Polarization Maintaining In-Line Polarizer is a compact fiber-optic polarizing component designed to transmit light along one defined polarization axis while strongly suppressing the orthogonal polarization. Integrated with polarization maintaining fiber, it provides stable linear polarization output, high extinction ratio, and low insertion loss for 1550nm optical systems. This in-line polarizer is suitable for fiber lasers, coherent optical systems, interferometers, fiber sensors, fiber amplifiers, fiber optic communication systems, and other polarization-sensitive applications. Custom optical power levels, input/output fiber types, pigtail lengths, pigtail diameters, and connector options are available.
Specifications
Parameter | Unit | Value |
|---|---|---|
Center Wavelength | nm | 1550 |
Operating Wavelength Range | nm | ±50 |

Max Optical Power (CW) | W | 0.5/1/3/5/10 |
Input Fiber Type | - | SMF-28e or PM1550 |
Output Fiber Type | - | SMF-28e or PM1550 |
Tensile Load (Max.) | N | 5 |
Package Dimensions | mm | Φ5.5 x L35 (≤5W) or 60 x 12 x 8 (≥5W) |
Operating Temperature | °C | -5 to +70 |
