Q1: What are the operating wavelength and splitting ratio of this 2×2 PM Filter Coupler?
A: This product operates at a wavelength of 850nm, with a bandwidth of ±20nm and a standard splitting ratio of 50/50. It is suitable for dual-port polarization-maintaining optical path distribution applications in the 850nm band.
Q2: What are the main performance characteristics of this product?
A: This product features low insertion loss, high extinction ratio, dual-axis operation capability, and high stability and reliability. Its insertion loss is ≤4.3dB, return loss is ≥45dB, and maximum power handling is ≤500mW, meeting the needs of medium-power polarization-maintaining optical systems.
Q3: Does this 850nm PM Filter Coupler support customization?
A: Customization is supported. Different operating wavelengths, splitting ratios, package sizes, fiber types, fiber lengths, and connector types can be selected according to requirements. The standard configuration uses PM780-HP Fiber 900μm loose tube, with an optical fiber length of 1.0±0.05m, FC/UPC connector, and supports Dual Axis working.
