FBT coupler 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.SZOPT provides a whole series of 1xN and 2xN splitter products that are tailored for specific applications. All products meet GR-1209-CORE and GR-1221-CORE.Both tree and star type inline couplers/splitters are available.Our items provide a reliable solution to split/combine signals.Single,dual,and tripple wavelength windows(1310/1490/1550nm) are available.
Fiber Optic FBT Coupler 1X2 1X3 SC/LC/FC/ST UPC APC
To keep the whole quality of our couplers are under strict quality control system,including all the incoming raw materials and every process during the production,only one has passed all the tests can be shipped to our customers.
