The GKER Multimode Fiber Filter Coupler Series delivers outstanding performance with its minimal excess loss, broad operating wavelength range, and high stability. Designed for precision and reliability, this coupler is available in both 1 × 2 and 2 × 2 configurations to suit various needs. It efficiently handles wavelengths of 1310 nm and 1550 nm, with a tolerance of ± 40 nm, making it versatile for different applications.

Engineered to support various tap ratios including 5 ± 1.0% and 50%, or specified ratios, the coupler ensures optimal signal distribution. Its high uniformity, ranging from 0.6 to 0.8 dB, guarantees consistent performance across different setups. Compatible with multimode fibers such as 62.5/125 µm, 50/125 µm, and 105/125 µm, it adapts to various fiber types and environments.

The coupler operates reliably within a broad temperature range of -5°C to +70°C and withstands storage conditions from -40°C to +85°C. With a maximum continuous wave optical power handling of up to 300 mW, it is well-suited for demanding applications in LAN networks, multimode fiber communication systems, fiber sensors, and testing instruments.
