Integrated 1/spl times/32 PLC-splitter with 32 WDM couplers for fiber line testing at 1.65 /spl mu/m

A novel silica-based PLC-splitter integrated with couplers is proposed for a PDS transmission system with fiber line testing. A 1/spl times/32 splitter with 32 WDM couplers formed using 1.65 /spl mu/m-reflecting thin film filters is demonstrated.
