The E-Tek Integrated Dual Stage Isolator/WDM is a combination of a polarization independent optical isolator and a 1480nm/1550nm WDM combiner. The device is ideal for high-power applications. This integrated component has extremely low polarization sensitivity, low insertion loss, and high isolation. Designed for compact and easy installation, it eliminates splices, requires less fiber routing, and reduces losses when compared to discrete components.
