A 1x4 optical splitter is a passive device that distributes a single optical signal from an input fiber to four output fibers. It operates without the need for power or electronics, using internal waveguide technologies to divide the light signal.
A 1x4 splitter uses a 1x2 stage followed by two 1x2 stages, creating four equal outputs. Ideally, each output receives 25% of the input power, minus splitting loss (~6 dB) and excess loss (~0.2–0.4 dB). 1x4 Nadi...
