Wherein in an embodiment, spectrum part 70 is planar light branch waveguide chip.
Wherein in an embodiment, spectrum part 70 comprises input end and output terminal, and input end comprises n passage, and output terminal comprises m*n passage.Wherein, n is positive integer, m be not less than 2 positive integer.In the present embodiment, m gets 2.
Wherein in an embodiment, as Figure 7-8, the input end of spectrum part 70 comprises 4 passages, and it is 8 passages that output terminal comprises.Particularly, encapsulate by 4 passage QSFP the input of passage as spectrum part that standard gets 4 road optical fiber of input part 10, meet 4 passage QSFP to make the joints of optical fibre and encapsulate standard.Spectrum part 70 is divided into two the light of each passage of input end, in the channel pitch preset and light splitting ratio, and the luminous power of parallel output 8 passage.The luminous power of adjacent two passages, wherein route first output terminal 75 transmitting optical signal is to efferent 30, is used as to continue transmitting optical signal; Another route second output terminal 77 transfers to photodetection portion, as real-time monitoring optical power and feedback.
