The invention provides cascaded Fabry-Perot filters having a plurality of optical fibers within a single F-P cavity. Of particular interest are cascaded FFPs having two, three or four optical fiber paths in the filter. An all-fiber FFP filter has a ferrule assembly having two or more aligned fiber ferrules, each having a plurality of optical fibers bonded into axial bores. Mirrors within the ferrule assembly transverse to the fibers from the F-P cavity. The FP filters can be fixed wavelength or tunable by changing an air gap within the cavity. The invention also provides ferrule holders useful for maintaining alignment of and for tuning the air gap of ferrule assemblies. The holders are particularly useful for construction of cascaded F-P filters.
