What is the relationship between optical splitters and optical fibers
An optical splitter is a crucial passive fiber optic device that splits and combines optical signals. It can distribute the optical energy transmitted through a single fiber to two or more fibers in a predetermined ratio or combine the optical energy from multiple fibers into one. Fiber optic splitters are essential passive devices in modern optical communication systems, enabling the division of a single light signal into multiple outputs or combining multiple signals into one. It can divide the input optical signal into multiple output optical signals to meet the fiber optic access needs of multiple terminal devices. -
