What is the function of the optical fiber splitter
Wave splitting involves dividing a light beam into multiple streams. The daughter streams can be equal or in some other ratio. The FBT splitter uses two (or more) fibers. The fibers' coating layer is removed. Both fibers, at the same time, are stretched under a heating zone thus forming a double cone. This special waveguide structure allows control of the splitting ratio via controlling length of the fiber torsion angle and stretch.

How to connect a Huawei single-mode module to an optical fiber
Use a single-mode fiber jumper for a single-mode optical module. Determine the optical connector type based on the interface type. Unidirectional single-fiber communication enables a device to send but not receive packets or, conversely, to receive but not send packets. Enter system view, return user view with return command. A single fiber means that two optical modules are connected by only one fiber, and unidirectional communication means that packets can be sent in only one. A switch must use optical or copper modules that have been certified for use on Huawei switches. Non-certified optical or copper modules cannot ensure transmission reliability and may affect service stability.
