What aspect does the X Coupler specifically deal with in optical fibers?

The X Coupler is specifically designed to divide optical power between two output fibers, making it instrumental in optical networks that require splitting signals to reach multiple destinations. This functionality is vital because it allows for efficient use of the optical signal, ensuring that the transmitted data can be distributed without significant losses.

By utilizing a coupler, the optical system can maintain high performance levels while accommodating multiple outputs, which is essential in applications such as point-to-multipoint configurations in fiber optic networks. The operation of an X Coupler is based on the principle of passive splitting, effectively distributing the light from one input fiber to two output fibers, each receiving a portion of the power.

Other options refer to distinct functionalities. Checking for fiber continuity is a separate testing process, measuring loss due to Rayleigh backscatter involves understanding signal degradation instead of splitting, and providing termination for Blown Optical Fibers relates to the physical termination process rather than signal division. The X Coupler’s role in power division is what clearly distinguishes it, making it an integral part of optical fiber configurations where multiple connections or branches are needed.
