DK Photonics Fibre Optical fused Couplers are the key elements in fibre-optic networks for the redistribution of optical signals. Fibre coupler devices are used as small components within various optical modules and systems for long-distance signal transmission, signal amplification, monitoring, and conditioning. These devices are used extensively in fiber amplifier power control, and in transmission equipment for performance monitoring and feedback control. Our ultra-low polarization dependent loss couplers offer low levels of sensitivity to polarization, enable more effective monitoring and management of optical networks.
