单模光纤耦合器分为拉锥式和膜片式,用于将单模光纤的输入按既定的分光比分成两个输出,广泛应用于光纤激光器、光纤放大器,光纤通信以及光纤传感等领域,具有体积小、低插入损、低偏振相关损耗、高稳定性。

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.
