There is two fabrication process for single mode fiber wavelengthdivision multiplexer base on fused biconical taper (FBT) technology and on thin-film filter technology, The couplersallows a single fiber input to be split into 2 outputs based on coupling ratioand it is ideal for fiber laser、fiber amplifier、fiber communication and fiber sensor. Csrayzer’s Coupler has low Insertion、compacted configuration、high return loss、high stability and reliability.
