How does a fiber optic splitter work? | Fibercan

A fiber optic splitter is a device used to divide an optical signal into multiple smaller signals. It works by using an optical coupler, which consists of a length of optical fiber with two or more splitters in the middle. The optical signal enters the coupler, and is split into two or more paths. Each of the paths is connected to an output port, which is then connected to a separate device. The splitter works by reflecting a portion of the signal back to the input port, while allowing the rest of the signal to continue through the output ports. The amount of signal that is reflected is determined by the ratio of the coupler, which is typically 1:2, 1:4, 1:8, or 1:16. This allows the signal to be divided into equal parts and sent to multiple devices. Fiber optic splitters are typically used in applications such as telecommunications, cable television, and audio/video systems. They are used to connect multiple devices to a single optical signal, and can also be used to increase the number of devices that can be connected to a single signal. 

The splitters are typically made of fused biconic taper (FBT) technology and are designed to reduce signal loss and maintain signal integrity. The FBT technology works by taking the input signal and splitting it into two parts, each with a different transmission path. The splitters are designed to be used in both single-mode and multi-mode fiber optic networks. They are commonly used in fiber optic networks for splitting signals for multiple destinations, such as for distributing signals to multiple users. They are also used in fiber optic systems for reducing signal loss and improving signal integrity.

Additionally, they can be used to extend the range of a signal, as the signal can be split and sent to multiple locations, allowing for longer distances between devices.
