PLC Splitter ABS Cassette

     The PLC optical splitter is a core passive component in the FTTH system. Optical splitter, is an integrated

waveguide optical power distribution device that can split an input optical signal into two or more output

optical signals, and the optical input power is evenly distributed on all output ports.

     For example, an optical splitter with a splitting ratio of 1:4 can divide an optical signal into four evenly, and

then transmit it in four different channels. At present, the splitting ratio of the optical splitter is generally 1:N

or 2:N, such as 1:4, 1:8, 1:16, 1:32, 2:16, 2:32.

     The working principle of the optical splitter is: when a single-mode fiber conducts optical signals, the energy

of the light is not completely concentrated in the core and a small amount is transmitted through the cladding

close to the core, that is to say If the cores of the two optical fibers are close enough, the mode field of the light

transmitted in one optical fiber can enter the other optical fiber, and the optical signal is redistributed in the two

optical fibers.
