Fiber optic splitter
Fiber optic splitter is device with at least three or more fiber optic ends; The function of fiber optic coupler is to split the input fiber optic light into several parts to the output fiber ends at a certain ratio. The fiber optic coupler can be made with single mode fiber optic coupler can be made with single mode fiber optic cable or muti mode fiber optic cables, the multimode fiber optic cable transmission distance and transmission bandwidth is less than single mode fiber cable.

There are single window fiber optic splitter and dual window fiber optic splitter. Single window means single wavelength with a narrow wavelength window, dual window fiber optic splitter is with two wavelengths with a wide wavelength window for each. Fiver optic coupler specification include the numbers of input and output, usually input is one cable port while output is many cable ports, the fiber optic splitter can be with different kinds of fiber optic connectors, usually it is with DC/PC, SC; APC, or LC fiber optic connectors. Input and output cables length is also optional, for example, 1 meter input cable length and 1 meter for each of the output cable length. Insertion loss refers to the attenuation caused by insertion of fiber optic components.
