  • Product Detail

fbt splitter is a type of optical power management device that is fabricated using Fused Biconical Tape technology.
It features small size, high reliability, cheap cost and good channel-to-channel uniformity, and is widely used in PON networks to realize optical signal power splitting.
Anfkom provides whole series of 1xN and 2xN splitter products that are tailored for specific applications. All products meet GR-1209-CORE and GR-1221-CORE
Anfkom offers both tree and star type inline couplers/splitters. They provide a reliable solution to split/combine signals. The splitting ratio ranges from 1×2 to 1×4 ports for tree couplers, and from 2×2 up to 4×4 for star couplers. Available in single, dual, and tripple wavelength windows(1310/1490/1550nm).
