The Fiber Optic Splitter, also named beam splitter, is based on a quartz substrate of integrated waveguide optical power distribution device, the same as coaxial cable transmission system, The optical network system also needs to be an optical signal coupled to the branch distribution, which requires the fiber optic splitter, Is one of the most important passive devices in the optical fiber link, is optical fiber tandem device with many input terminals and many output terminals, Especially applicable to a passive optical network (EPON, GPON, BPON, FTTX, FTTH etc.) to connect the MDF and the terminal equipment and to achieve the branching of the optical signal.
According to the Fiber Optic Splitter principle, it can be divided into FBT Splitter and PLC Splitter.
Splitting Ratio principle
- FBT SPLITTER makes two (two or more) fibers removed the coating layer gather in a certain way, stretched to both sides under the heating zone at the same time, form a double cone’s special waveguide structure finally for getting a different splitting ratio via controlling length of the fiber torsion angle and stretch
- PLC SPLITTER is a micro-optical element using photolithographic techniques to form optical waveguide at medium or semiconductor substrate for realizing branch distribution function
- FBT SPLITTER: Operating wavelength, Operating bandwidth, typical additional loss, insertion loss, polarization dependent loss, uniformity and directivity and splitting ratio
- PLC SPLITTER: Operating wavelength, insertion loss, uniformity, return loss and polarization dependent loss
