Design of Narrow Bandpass Filter Used in DWDM System for Optical Fiber Communication

LI Fang, LIN Yong chang (Dept. of Optical Engineering, Beijing Institute of Technology, Beijing100081, China)  
To realize the multiplexing/demultiplexing function and avoid the isolation, by adopting the multi cavity F P filter, the narrow bandpass filter with rectangle passband, little ripple and high signal noise ratio is designed for the DWDM system. The designed filter has the qualified pass band width and little ripple, its low insertion loss and exact center wavelength meet the communication specification. And it is easy to be manufactured.
