The GKER Singlemode Broadband Coupler Series delivers high performance with exceptionally low insertion loss, minimal polarization dependence, and superior environmental stability. Designed for precise signal management, it offers coupling ratios ranging from 50/50 to 1/99 with excellent uniformity across a broad wavelength range.

This coupler operates effectively at standard wavelengths of 1310 nm and 1550 nm, or other specified wavelengths, and provides reliable performance with a maximum insertion loss of 21.5 dB for 1 × 2 configurations and 7.5 dB for 2 × 2 configurations. Its low polarization dependent loss (PDL) of 0.10 dB ensures consistent signal quality, while its high return loss of 50 dB maintains signal integrity.

Engineered for robustness, the coupler handles continuous wave optical power up to 300 mW and remains stable within an operating temperature range of -5°C to +70°C, with storage capabilities from -40°C to +85°C. Ideal for use in optical communication systems, it excels in power splitting and monitoring applications, providing reliable and efficient performance in various setups.
