The function of single mode fiber optic coupler is that it could make the signal transferring in optic fiber coupling in the couple section, and redistribute the optic power.The main structure including: star and tree, main technical perform-ance parameter including center wavelength, band-width, excess loss, couple ratio and polariza
-tion dependent loss, etc. FOE's product are manufactured using FBT(Fusing Biconical Taper) techinics. It is a coupler was made of whole optic fiber and has excellent application characteristic .

Features:
1.Low polarization dependent loss
2.Low excess loss
3.Excellent directivity
4.Environmentally stable
5.Multi type of structure: standard, flat, broadband, star, tree.

Application:
1.Fiber optic communication system
2.Optical fiber CATV
3.EDFA
4.Optical fiber access network
5.M onitoring system
6.O ptical sensor
7.P hotosource Distributor
