Description
The GKER Polarization Maintaining Fused Coupler (GK-PMC Series) is a high-performance optical component designed for precision and reliability across a broad wavelength range of 488 nm to 2100 nm. This coupler excels in applications requiring low excess loss, high polarization extinction ratio (ER), and exceptional environmental stability.
Engineered with advanced fusion technology, the GK-PMC Series offers typical excess losses as low as 0.2 dB and a high polarization extinction ratio up to 20 dB, ensuring minimal signal degradation and superior performance in polarization-sensitive applications. The coupler is available in coupling ratios from 0.01/99.99 to 50/50, catering to various needs from fine power splitting to high power handling.
Designed for durability, this coupler supports continuous wave optical power up to 2 W and maintains high performance within an operating temperature range of -5°C to +70°C and a storage temperature range of -40°C to +85°C. Its low thermal sensitivity, with a stability of ≤ 0.005 dB/°C, ensures reliable operation in diverse environments.
The GK-PMC Series is ideal for critical applications such as fiber amplifiers, fiber gyroscopes, and coherent communication systems, providing the precision and stability needed for advanced optical testing and monitoring.
