Claim 0:
1. An optical integrated device, which is used to split a detecting light from a first pigtail into two split detecting lights, respectively couple the split detecting lights to a second pigtail and a third pigtail and couple the split detecting light returned from the second pigtail to the third pigtail, comprising:
a packaging outer shell;
a first collimator, an optical splitting device, a circulator assembly and a second collimator which are sequentially provided in the packaging outer shell;
the optical splitting device being provided close to the first collimator, being used to reflect a part of the detecting light from the first pigtail and couple the part of the detecting light to the third pigtail, and allowing the other part of the detecting light to pass through the optical splitting device;
the circulator assembly being provided close to the optical splitting device, the circulator assembly being used to couple the detecting light passing through the optical splitting device to the second pigtail, and couple the detecting light returned from the second pigtail to the third pigtail.
