Hole is respectively fixed with a Loose tube by glue in through-hole, and there is connector in the Loose tube end by plug connection, under described
Shell top left side is equipped with fixing seat by bolt, is provided with concave groove at the top of the fixing seat, is inlaid with Loose tube in concave groove,
Set casing is fixed with by glue at the top of the lower casing, Mux/demux component, the Mux/ are socketed with inside the set casing
Demux component left side wall has an AWG line by plug connection, and the AWG line is placed in the Loose tube on the left of lower casing, described
By plug connection there are four FA line, the FA line is placed in the Loose tube on the right side of lower casing Mux/demux component right side wall, and four
FA line bottom passes through fixed at the top of glue and lower casing.
Preferably, the FA line corresponds to a Loose tube on the right side of lower casing.
Preferably, FA line bottom surface is lower than AWG line bottom surface.
Preferably, the upper casing bottom has been bolted fixing seat, the fixing seat of the upper casing bottom and lower casing top
The fixing seat in portion contacts.
Compared with prior art, the utility model has the beneficial effects that the setting of the CWDM4 wavelength division multiplexer, structure are set
Meter rationally, in lower shell upper portion is equipped with Mux/demux component, and point of CWDM4 wavelength signals is realized in the use of Mux/demux component
Involve multiplex.
