Characteristics and applications of high performance, tunable, fiber Fabry-Perot filters

The unique characteristics (stable optical performance, inherently pigtailed, insertion loss <2 dB, finesse >100) of tunable, fiber Fabry-Perot (FFP) filters allow diverse optical signal processing necessary for third-generation wavelength division multiplex (WDM) systems and wavelength division multiple access (WDMA) networks. After describing the FFP characteristics, the author discusses the WDM long-haul field experiment and the prototype IBM Rainbow WDMA network. Other applications for this filter technology are EDFA noise filters, channel switches, and signal processors for extremely broadband ISDN (integrated services digital network) and digital high-definition TV distribution systems.<
