DK Photonics uses unique fusing technique to build 1310~1550nm High power SM fiber Fused Coupler are used to split off a portion of light to allow for optical monitoring and feedback. These devices are used extensively in fiber amplifier power control, and in transmission equipment for performance monitoring and feedback control. High power SM fiber Fused Coupler is widely used for High Power Fiber Laser and High-Power Fiber amplifier.
If you do not see a standard High power SM fiber Fused Coupler that meets your needs, we welcome the opportunity to review your desired specification and quote a custom fused Coupler. Requests for custom fiber pigtails, different wavelengths, tap Ratio and handling power of operation or other specific needs will be readily addressed.
