9. the novel double double packaging technologies for receiving single fiber four-way optical device of hair of one kind according to claim 6, it is characterised in that:
High temperature roasting glue described in step 6 is cured as epoxy resin adhesive curing, and temperature is controlled at 85 DEG C ± 10 DEG C, 80~100 points of the time
Clock.
10. the novel double double packaging technologies for receiving single fiber four-way optical device of hair of one kind according to claim 6, feature exist
In: temperature cycles described in step 7 recycle between -40 DEG C~85 DEG C, wherein -40 DEG C and 85 DEG C of thermostatic hold-time is at least
30 minutes are a cycle period, and circulation is no less than 40 periods every time.
