Introduction

The 2x2 Single Mode FBT Coupler are used to stretch two or more fibers to both sides when melting at high temperatures. They are mainly used in PON networks, network communication systems, optical fiber sensing systems and measuring instruments. Secondly, they are the most important passive components. More importantly, our products are made of high-quality raw materials and have the characteristics of durability. Finally, if you are interested in our products, please contact us in time.

Feature

The 2x2 Single Mode FBT Coupler structure is simple, there are no other structural components, relatively speaking, FBT can be very convenient to connect and integrate with the transmission optical fiber, and the loss is also very low. Secondly, we are characterized by ultra-low insertion-dependent losses and high return losses. More importantly, our core material is high purity silica, the cladding material is doped silica, and the coating layer is mainly to protect the optical fiber. Finally, our products are of good quality.
