1480/1550nm WDM-Tap Coupler-Isolator Hybrid Combination
A 2x2 WDM device with a hybrid integration of isolators and splitters. Port 1 Connects to the erbium-doped optical fiber side. The input beam passes through a dual fiber collimator and the beam is collimated. The collimating beam passes through the double isolator core, and the beam is divided into two parts by the splitter prism, and enters the double fiber collimator port 3 and 4 respectively.
