Fiber optic splitter 1x2 SC/APC mini G657A1,1m

A fiber optic splitter, also referred to as an optical splitter, PLC splitter, or beam splitter , is a passive optical device that splits incoming light signals into multiple signals.Basically, there are two types of optical fiber splitters. That is a PLC splitter (planar lightwave circuit splitter) and an FBT splitter (fused biconical taper splitter). They are used for PON networks. 

PLC splitter is based on Planar Lightwave Circuit technology. It divides signals equally and is denoted with a 1xN or 2xN split ratio, where the first number is the number of inputs and N is the number of outputs.  Fiber optic splitters are high-quality with low failure rates that offer precise equal splitting for 1260 nm to 1650 nm operating wavelengths. In addition, PLC splitters are available in a variety of split ratios, for example, 1x4, 1x8, 1x16, 1x32, and 1x64, etc. Ratios are selected depending on factors such as required speed, distance, and number of users.

Sometimes Fiber optics plitters PLC come with two incoming signals, such as 2x8, 2x16, etc. These splitters  are used for redundancy where the two incoming signals come from separate OLTs or line cards within an OLT.

By package, there are several types, such as bare fiber optic splitter, blockless optical splitter, ABS module fiber splitter, LGX splitter PLC, PLC splitter 19-in rack,and universal splitter module (USM). You can read the article “How much do you know about fiber optic splitter?” for more information about optical splitters.

How Does Fiber Optic Splitter Work?

Fiber optic  splitter acts like a traffic divider for light signals in fiber networks.It’s main components include input port(s), output ports,couplers, fiber array,and a protective shell.

Do you know how does it work? When an optical signal enters the input port, the coupler inside the splitter can help split the signal into multiple paths that lead to the output ports of the splitter. An optical splitter allows the split signal to exit the device and safeguard stable transmission along separate channels. The distribution of the signal is determined by the splitting ratio, which varies with different splitter configurations.

Specifically speaking, the fiber optic splitter can split, or separate, an incident light beam into several light beams at a certain ratio. For example, a 1x8 PLC splitter will equally divide the input optical signal energy into 8 parts, with each part having an optical signal that is 1/8 of the original input signal power.
