1550nm Tap Coupler/Isolator Hybrid Combination

DK Photonics’s 1550nm Tap Coupler/Isolator Hybrid Combination is a combination of a tap coupler and an isolator in a compact package. All input and output fibers are polarization independent. This product has an extremely a very stable tap-coupling ratio, high isolation, and hight return loss. This product offers integrated solution to fiber amplifier application by combining more functions into a very compact package.
