FBT Splitter with Low Insertion/PDL Loss and Splitting Ratio custmize available

Optical splitter: Like the coaxial cable transmission system, the optical network system also needs to couple, branch, and distribute optical signals, which requires an optical splitter. FBT optical splitter, also known as optical splitter, is one of the important passive components in optical fiber circuits, and it is an optical fiber junction device with multiple input ends and multiple output ends. MxN is often used to indicate that a splitter has M input ends and N output ends. The optical splitters used in fiber optic CATV systems generally have 1*2, 1*3 and 1*N optical splitters composed of them. Router. Features: (1) Low additional loss and low polarization-related loss, good stability; (2) Flexible working windows: single working window, double working window and three working windows; (3) High wavelength isolation (4) Optional split ratio (5) Small package size and small space occupation Applications
