• Precision Polarization Control

Our Faraday Rotation Mirror offers a precise 45° single - pass rotation (with ±3° tolerance) for input light polarization. Using advanced tech, it ensures low insertion loss (typical 0.7dB, max 0.8dB) and stable performance across wavelengths (980/1064/1310/1550nm), critical for polarization - sensitive systems.

• Flexible Customization

We support diverse fiber types (125/250μm, 80/160μm fine diameter), package diameters (3.0x12mm, 2.5x12mm), and connectors (FC/UPC, FC/APC, etc.). Via the ordering system, you can tailor wavelength, tube type, and fiber length-no generic "one - size" limits.

• Harsh - Environment Reliability

With an operating temp range of - 5°C~+70°C and storage temp of - 40°C~+85°C, our FRM handles extreme conditions. Low polarization - dependent loss (0.1dB max) ensures consistent performance in telecom, laser, or sensing applications-reducing downtime risks.

 

 

Q1: How does the 45° rotation benefit my system?

A1: The 45° rotation (Faraday effect) helps in polarization - diverse setups (e.g., coherent detection, interferometry). It ensures light returns with a rotated polarization, minimizing signal fading and improving system stability-key for high - precision applications.

Q2: Can I use it with both standard and fine - diameter fibers?

A2: Yes! We support 125/250μm (standard) and 80/160μm (fine - diameter) fibers. Just select "1 - SMF - 28E" or specify fine - diameter in the ordering system-we'll match your fiber type.

Q3: Is it suitable for outdoor telecom networks?

A3: Yes. Its wide temp range (- 5°C~+70°C operating, - 40°C~+85°C storage) and rugged design (loose tube, bare fiber options) make it ideal for outdoor deployments. The low insertion loss also ensures reliable long - haul signal transmission.
